4DI 2DO Three Phase Panel Mounted Multi-function Panel Meter for Electricity Distribution

Product Overview

The Smart X96-5G is a three phase panel mounted multi-function panel meter for electricity distribution. It is designed for panel board installation and is built around a 96 mm by 96 mm front profile, a widely used size for industrial and commercial electrical cabinets. Its depth is approximately 92 mm, and it weighs about 420 g, making it compact enough for integration into new distribution panels and retrofit projects.

The instrument measures and displays key electrical parameters in single and three phase systems, including voltage, current, frequency, power, active energy, reactive energy, apparent power, power factor, maximum demand, harmonic distortion, and imported or exported energy. The product supports 1P2W, 3P3W, and 3P4W electrical networks, giving engineers flexibility when standardizing panel instrumentation across different project types.

The meter’s rated current input is 5 A, making it suitable for CT-operated installations. The measurable current range can be scaled through CT ratio settings, allowing applications from small distribution circuits to large feeders. The product supports a maximum current value display or configuration range up to 9999 A, a minimum current of 0.25 A, and a starting current of 20 mA. This combination helps the device respond to both low-load and normal operating conditions in a practical electrical distribution environment.

For voltage measurement, the meter supports measured voltage ranges of 50 V to 600 V in 3P4W networks and 50 V to 480 V in 3P3W networks. The auxiliary power supply is available as 230 V L-N AC or 120 V to 380 V DC, supporting common control panel power arrangements. Such flexibility reduces engineering constraints and simplifies specification across multiple markets.

One of the most important aspects of this product is its multi-function nature. Instead of using separate meters for energy, power, demand, harmonics, and alarms, a panel builder can use one compact instrument. This improves panel appearance, reduces wiring complexity, decreases component count, and provides centralized data through RS485 Modbus RTU communication.

Key Technical Features

The meter is engineered for RMS measurement including harmonics on three phase AC systems. This is important because non-linear loads are now common in commercial and industrial facilities. Variable frequency drives, switch-mode power supplies, LED lighting systems, UPS equipment, EV charging infrastructure, and modern automation equipment can create harmonic distortion. A meter that measures only fundamental values may not provide enough information for troubleshooting power quality. By measuring harmonics up to the 63rd order, this meter gives users deeper visibility into electrical behavior.

The product provides multi-parameter measurement, including voltage, current, power, energy, frequency, power factor, demand, and harmonics. It also supports bar graph indication for power, giving operators a quick visual understanding of load condition without needing to interpret multiple numerical values. The backlit LCD display is designed for wide viewing angles, improving readability in panel rooms where lighting and viewing position may be less than ideal.

Communication is provided through an RS485 port using Modbus RTU. The interface is two-wire half duplex, with baud rates of 2400, 4800, 9600, 19200, and 38400 bps. The address range is 1 to 247, parity options include none, even, and odd, and stop bit settings include 1 or 2. These options enable integration with building management systems, energy management platforms, PLCs, data concentrators, gateways, and SCADA systems.

The product includes 4 digital inputs and 2 digital outputs. Digital inputs can be used for external signal counting or status monitoring. Digital outputs can be used for external device control or alarm-related functions, depending on system design. This I/O capability is a strong advantage compared with basic panel meters that provide measurement only. In many applications, DI/DO functions reduce the need for separate I/O modules, simplify wiring, and make the meter more valuable as part of a smart distribution system.

The product can support multi-tariff functions when the real-time clock option is available. Multi-tariff metering is valuable in energy cost allocation, tenant billing support, time-of-use analysis, and facility energy optimization. When energy tariffs vary by time period, the meter’s ability to separate consumption into tariff periods helps operators understand when power is being used and how costs can be controlled.

Event recording is another practical function. The meter can provide SOE recording with time information. Sequence of events records help maintenance teams understand what occurred and when. In a distribution panel, this can support fault analysis, alarm investigation, and operational review. The product can also support alarm parameter configuration, with 30 types of parameters available for alarm setting, helping users transform electrical measurements into actionable notifications.

Measurement Accuracy and Practical Value

Accuracy is one of the most important purchasing criteria for a panel mounted multi-function meter. Inaccurate measurement can lead to wrong decisions, incorrect energy allocation, poor demand management, and unreliable system diagnostics. The Smart X96-5G provides high accuracy for energy and electrical parameter measurement, including active energy accuracy according to IEC 62053-22 Class 0.5S and IEC 62053-21 Class 1.0.

For active power, reactive power, and apparent power, the measurement accuracy is 1.0% of range maximum. Current and voltage accuracy are 0.5% of range maximum, while frequency accuracy is 0.2% of mid-frequency. Power factor accuracy is 1% of unity, or 0.01. Total harmonic distortion measurement is 2% up to the 63rd harmonic. These specifications make the meter suitable for electricity distribution monitoring where a balance of accuracy, cost-efficiency, and multi-function capability is required.

Class 0.5S active energy measurement is especially valuable for distribution panels that support cost allocation, operational benchmarking, efficiency programs, or sub-metering. Compared with lower accuracy instruments, Class 0.5S performance helps reduce uncertainty, particularly under lower load conditions. For building managers and industrial operators, this can provide better confidence in monthly energy analysis and long-term energy saving projects.

Accuracy is not only a laboratory value. It also depends on reliable design, stable electronics, proper isolation, quality components, manufacturing process control, calibration, and testing. Eastron Electronic Co., Ltd. supports product reliability through its professional laboratory, which is capable of performing EMC, LVD, accuracy, and environmental tests according to IEC, EN, GB, and UL-related standards. This in-house test capability helps ensure that products are not merely designed to meet specifications, but are also verified under controlled procedures before reaching customers.

Harmonic Measurement up to the 63rd Order

Harmonic measurement is an important advantage of this panel meter. Many basic meters provide voltage, current, power, and energy, but do not offer detailed harmonic visibility. Others may provide only total harmonic distortion or limited harmonic order measurement. The ability to measure up to the 63rd individual harmonic distortion gives the user a more complete view of power quality.

In modern facilities, harmonic distortion can cause transformer heating, neutral conductor overload, nuisance tripping, capacitor bank stress, motor vibration, reduced equipment life, and energy losses. Harmonics are often introduced by non-linear loads. These loads draw current in pulses rather than smooth sinusoidal waveforms. Without harmonic data, a maintenance team may see symptoms but not understand the cause.

With harmonic analysis up to the 63rd order, the meter supports better troubleshooting. For example, if a facility experiences overheated transformers or unexpected neutral current, the meter can help identify whether specific harmonic components are present. If variable frequency drives or UPS systems are producing distortion, electrical engineers can use harmonic data to evaluate mitigation strategies, such as passive filters, active harmonic filters, line reactors, or system redesign.

This is a competitive advantage over simpler panel meters that focus only on billing-style energy measurement. The Smart X96-5G provides both energy data and power quality insight, allowing the user to make better technical decisions from a single panel device.

Digital Inputs and Outputs for Smarter Panels

The inclusion of 4 digital inputs and 2 digital outputs gives the meter strong application flexibility. A traditional panel meter is often a passive measuring device. It displays values and perhaps sends measurements to a monitoring system. A meter with digital inputs and outputs can interact more directly with the electrical environment.

Digital inputs can be used to collect external status signals. For example, they may monitor breaker status, relay state, pulse outputs from other devices, door contacts, or operating signals from electrical equipment. In some applications, they can be used for external signal counting. This allows the meter to act as a compact data acquisition point inside the panel.

Digital outputs can support alarm indication or external device control. When certain electrical parameters exceed configured limits, output signals can be used to trigger alarms, communicate with external relays, or integrate with control logic. The availability of 30 types of alarm parameter settings increases the practical value of these outputs. Instead of waiting for a central system to process all conditions, some local responses can be configured at the metering level.

Compared with competing basic meters that require additional modules for field signal integration, the 4DI 2DO configuration reduces system cost and wiring complexity. It also saves panel space, which is often a decisive advantage in retrofit projects. For OEM panel builders, fewer components can mean faster assembly, less wiring labor, fewer terminal points, and reduced risk of installation error.

RS485 Modbus RTU Communication

RS485 Modbus RTU remains one of the most widely used communication solutions in electrical distribution monitoring. It is cost-effective, robust, and compatible with a broad range of gateways, PLCs, data loggers, energy management systems, and supervisory platforms. The Smart X96-5G supports RS485 Modbus RTU through a two-wire half-duplex port, making it practical for multi-drop networks in commercial and industrial installations.

The meter supports communication baud rates of 2400, 4800, 9600, 19200, and 38400 bps. Device addresses from 1 to 247 allow many meters to be placed on a network, depending on system design and RS485 limitations. Parity options include none, even, and odd, and the stop bit setting can be configured as 1 or 2. These choices make the instrument adaptable to existing communication environments.

In energy monitoring applications, Modbus RTU communication enables automatic data collection. Rather than sending personnel to read each panel, the facility can collect energy, demand, voltage, current, power factor, harmonic, and alarm-related data remotely. This supports energy dashboards, fault diagnosis, predictive maintenance, and power usage reporting.

From a competitive standpoint, a meter with standard Modbus RTU offers easier integration than proprietary communication devices. System integrators prefer open and familiar protocols because they reduce commissioning time and software development effort. The meter’s communication flexibility makes it well suited for energy management systems in factories, commercial buildings, campuses, data centers, distribution cabinets, and infrastructure projects.

Display, Installation, and Panel Integration

A panel meter must be easy to read, easy to install, and reliable in service. The Smart X96-5G uses a backlit LCD display designed for full viewing angles. This matters in real installations because operators may view the panel from the side, from below, or in low-light electrical rooms. A clear display improves daily usability and reduces reading errors.

The bar graph for power indication provides rapid visual feedback. Operators can quickly understand whether a feeder is lightly loaded, moderately loaded, or heavily loaded. While numerical data is important, visual indicators can speed up inspection and reduce the mental effort needed to interpret the panel condition.

The meter uses a push-in installation and plug-in connection concept, improving installation efficiency. Panel builders benefit from faster assembly and easier maintenance. Plug-in connection can also simplify replacement, testing, and servicing. In high-volume panel manufacturing, installation convenience can reduce labor time and improve consistency. In field retrofit work, it can shorten downtime.

The product’s 96 mm by 96 mm front size is a standard format for panel instrumentation. This makes it compatible with common panel design practices. A standardized size reduces mechanical design risk and allows the meter to replace or upgrade older instruments in many existing cabinets.

The mechanical design includes a self-extinguishing meter case material rated according to UL 94 V-0. This is important in electrical cabinets where fire safety and material behavior under heat or fault conditions are critical. Shrouded screw-clamp terminals help provide secure electrical connections and reduce accidental contact risk during installation and maintenance.

Environmental and Mechanical Reliability

The product is designed for demanding distribution environments. It operates from -25 °C to 55 °C and can be stored from -40 °C to 70 °C. Humidity tolerance is less than 95% RH at 50 °C, non-condensing. The pollution degree is 2, and the altitude rating is 2000 m. The front display protection is IP51 according to IEC 60529.

These specifications make the meter suitable for many indoor electrical distribution panels in commercial, industrial, and infrastructure environments. Temperature range is especially important because panel rooms can be warm, poorly ventilated, or affected by seasonal conditions. Storage range also matters for distributors and project sites where equipment may be stored before installation.

Mechanical reliability is supported by a compact structure and practical terminal design. The 420 g weight reduces mechanical burden on the panel door, and the 96 mm by 96 mm format provides sufficient display area without excessive panel space usage. The use of self-extinguishing UL 94 V-0 material contributes to safety-oriented design.

Competitive Advantages in Electricity Distribution

The Smart X96-5G stands out from many competitor products because it combines several functions that are often separated into different instruments. It is not simply a kWh meter, not only a power meter, and not only a harmonic analyzer. It is a panel mounted multi-function instrument with energy measurement, power quality visibility, communication, digital input and output, alarm setting, and event recording capability.

One major advantage is the combination of Class 0.5S active energy accuracy and up to 63rd harmonic measurement. Some competing meters provide accurate energy measurement but limited power quality analysis. Others provide power quality functions but may be larger, more expensive, or less convenient for panel installation. This product balances measurement depth and panel practicality.

A second advantage is the 4DI 2DO configuration. Many standard panel meters do not provide multiple digital inputs and outputs as a built-in feature. When a project requires external status monitoring or control outputs, users may need to purchase additional modules. The integrated DI/DO design can reduce cost, save space, and improve system simplicity.

A third advantage is Modbus RTU support with flexible serial settings. Because Modbus RTU is widely accepted, the meter can fit into many existing energy management and automation systems without locking the user into a proprietary ecosystem. For integrators, this means faster commissioning and lower technical risk.

A fourth advantage is user-friendly installation and operation. The push-in installation, plug-in connection, backlit display, bar graph indication, and compact 96 mm by 96 mm form factor all contribute to real-world usability. Competitor products may offer similar measurements but lack the same balance of installation efficiency and operator readability.

A fifth advantage is the manufacturer’s specialized focus on energy measurement solutions. Eastron Electronic Co., Ltd. develops and produces electricity meters, power analyzers, current sensors, communication modules, and management systems. This focused product ecosystem allows the company to understand the needs of panel builders, energy monitoring specialists, and distribution equipment suppliers.

Application Scenarios

The meter is suitable for electricity distribution panels in commercial buildings, industrial plants, public facilities, data rooms, infrastructure cabinets, renewable energy auxiliary systems, and energy monitoring projects. Its combination of voltage, current, energy, power, harmonic, and communication functions makes it useful wherever electrical performance needs to be understood.

Commercial Buildings

In commercial buildings, energy costs are often divided by floor, tenant, department, or functional area. The meter can support sub-metering and energy analysis by measuring active and reactive energy, demand, and power factor. With Modbus communication, the data can be collected by a building management system or energy management platform.

Industrial Facilities

Industrial plants often include motors, drives, welding equipment, compressors, pumps, and automation systems. These loads can create fluctuating demand and harmonic distortion. The meter’s harmonic measurement up to the 63rd order and maximum demand information can help engineers identify problem loads, evaluate system loading, and plan improvements.

Panel Board Manufacturing

For panel builders, the meter provides a compact and feature-rich option. Its 96 mm by 96 mm format, CT input, RS485 communication, digital inputs, digital outputs, plug-in connection, and broad measurement capabilities make it suitable for standardized panel designs. Using one multi-function device can simplify bill of materials management.

Energy Management Projects

Energy service companies and facility energy teams need reliable data to support audits, savings verification, and operational improvements. The meter provides the necessary electrical parameters for energy profiling. Multi-tariff capability, when available, further supports cost analysis in time-of-use tariff environments.

Power Quality Monitoring

While it is not intended to replace high-end portable power quality analyzers used for specialized investigations, the meter offers valuable permanent harmonic visibility. This makes it useful for continuous monitoring of feeders where distortion is a concern. Permanent monitoring helps detect issues that may not appear during a short-term manual survey.

The company is a high-tech manufacturer and supplier specializing in electricity products and energy measurement solutions. Its product range includes electricity meters, power analyzers, current sensors, communication modules, and management systems.

The company’s manufacturing strength begins with focused research and development. Its development teams in China and the United Kingdom support the design of new products and technologies. This international engineering approach helps the company maintain a competitive edge, respond to market requirements, and continuously improve product performance.

Cooperation with universities and institutions further supports innovation. By working with research partners, the company can bring advanced technologies into its products. In the electricity metering field, innovation is not limited to appearance or user interface. It includes measurement algorithms, embedded software, hardware design, electromagnetic compatibility, mechanical structure, communication reliability, calibration methods, and production test systems.

The company has established its own professional laboratory. This laboratory is capable of performing EMC, LVD, accuracy, and environmental tests according to relevant IEC, EN, GB, and UL standards. In-house test capability is an important manufacturing advantage because it helps shorten development cycles, improve verification depth, and support continuous quality improvement. Instead of relying only on external testing after a design is complete, engineers can evaluate performance throughout the development process.

The company follows the ISO 9001 quality management system, and its production is approved by SGS according to MID standards.

This matters for customers because electricity metering products have long service lives. Buyers prefer suppliers that can provide continuity, technical support, product evolution, and stable quality over time.

Advanced Manufacturing Process and Quality Assurance

A high-quality panel meter requires controlled manufacturing from component selection to final testing. Although the customer sees the final instrument mounted in a cabinet, the reliability of that instrument is built through many production steps. These include PCB assembly, component inspection, firmware programming, calibration, functional testing, communication testing, display inspection, enclosure assembly, environmental checks, and final quality verification.

For a multi-function meter, calibration and accuracy verification are especially important. Voltage, current, power, energy, frequency, and harmonic measurement all depend on the integrity of sensing circuits, analog-to-digital conversion, reference components, and embedded calculation algorithms. A strong manufacturing process ensures that each unit is adjusted and tested to meet defined performance levels.

Electromagnetic compatibility is also essential. Electrical distribution panels can contain contactors, relays, drives, inverters, communication wiring, and high-current conductors. A meter must continue to operate reliably in this environment. The company’s ability to perform EMC testing helps validate the product’s resistance to interference and its compliance with expected emission requirements.

Low voltage directive related safety testing and environmental testing also contribute to product reliability. Electrical meters are connected to voltage circuits and current transformer circuits, so insulation, creepage, clearance, terminal safety, and enclosure materials must be carefully designed and verified. Environmental testing helps ensure that temperature and humidity conditions do not compromise operation.

The use of self-extinguishing UL 94 V-0 case material is part of a safety-conscious design philosophy. Terminals, mechanical fit, display mounting, internal PCB layout, and external connection design all influence long-term dependability. For customers, these manufacturing and quality controls translate into reduced field failures, lower maintenance costs, and more stable performance.

Why This Meter Is a Strong Choice for Panel Builders

Panel builders need components that are reliable, easy to wire, easy to configure, and attractive to end users. A meter with many advanced functions is only valuable if it can also be installed efficiently. The Smart X96-5G addresses this by combining a standard panel size, clear display, plug-in connection, and multi-function measurement.

When panel builders choose a component, they consider not only the purchase price, but also the total cost of integration. A lower-cost meter may become expensive if it requires additional communication converters, I/O modules, separate harmonic monitors, or complex wiring. By integrating measurement, communication, DI/DO, alarms, and harmonic analysis, this product can reduce total panel complexity.

The Modbus RTU interface also gives panel builders a widely accepted communication option. Many customers specify Modbus for energy monitoring, and many automation systems already support it. This reduces the need for custom interfaces and makes the final panel easier to sell into diverse projects.

The 96 mm by 96 mm front format also improves the panel’s professional appearance. A clear LCD with bar graph indication gives the end user immediate visual feedback. This supports both technical operation and customer perception of quality.

Why This Meter Is a Strong Choice for End Users

End users need accurate data, easy operation, and dependable service. The Smart X96-5G supports these needs by providing broad electrical measurement in one device. Operators can view real-time voltage, current, frequency, power, energy, demand, power factor, and harmonic values directly from the panel.

The meter’s communication capability enables remote monitoring, which reduces manual reading and supports centralized energy management. This is especially important for facilities with many distribution panels. Instead of reading each meter individually, data can be transmitted to a central system for analysis and reporting.

Digital inputs and outputs add practical operational value. They can support status monitoring, signal counting, alarms, and device control. SOE recording with time information helps users investigate events. Alarm parameter settings allow the meter to support local warning strategies.

For energy managers, the meter’s multi-tariff option can support cost analysis where tariffs vary by time. Demand measurement can help identify peak load periods. Power factor data can support reactive power management. Harmonic information can identify power quality concerns before they become costly failures.

Energy Efficiency and Cost Control

Energy efficiency begins with measurement. A facility cannot effectively manage what it cannot see. By measuring active energy, reactive energy, active power, reactive power, apparent power, current, voltage, frequency, and power factor, the meter provides the data foundation for energy improvement.

For example, maximum demand values can help identify whether equipment starts simultaneously and creates unnecessary peak loads. Power factor measurement can reveal whether compensation is needed. Harmonic data can indicate whether inefficient distortion-related losses may be present. Multi-tariff data can show whether consumption can be shifted to lower-cost periods.

In many facilities, energy saving does not require one large project. It comes from continuous measurement, analysis, and operational adjustment. The meter supports this process by making data available locally and remotely. When connected to an energy management system, it can become part of a long-term efficiency strategy.

Power Quality Awareness

Power quality is increasingly important because electrical systems are becoming more electronically controlled. Harmonics, low power factor, voltage imbalance, and abnormal demand patterns can affect equipment performance. While the meter’s main role is panel-mounted distribution monitoring, its harmonic capability gives users valuable power quality awareness.

Up to 63rd harmonic measurement is particularly useful in facilities with variable speed drives, inverter-based equipment, and dense electronic loads. By continuously observing harmonic distortion, operators can detect trends. If harmonic levels increase after new equipment is installed, the facility can investigate before serious problems occur.

Competitor products without advanced harmonic measurement may leave the user blind to distortion problems. A basic kWh meter can show how much energy is used, but it cannot explain whether the electrical waveform is healthy. This meter helps bridge the gap between energy metering and power quality monitoring.

System Integration with Gateways and Management Platforms

Because the meter uses RS485 Modbus RTU, it can be integrated with gateways and higher-level management platforms. In many systems, multiple meters are connected on an RS485 bus, and a gateway transfers data to Ethernet, cloud platforms, or local supervisory software. This architecture is common in building energy management and industrial monitoring.

The meter can serve as a field data source for electrical distribution dashboards. Users can monitor load levels, energy consumption, power factor, and harmonic status from a central interface. Alarm data and digital input status can also be incorporated into the monitoring strategy depending on system configuration.

For system integrators, standardized communication and clear electrical parameters reduce engineering complexity. The availability of multiple baud rates, address settings, parity options, and stop bit configurations makes the device adaptable to different network requirements.

Company Capability and Global Service

Eastron Electronic Co., Ltd. provides products and services to more than 50 countries across Europe, Asia-Pacific, America, the Middle East, and Africa. This global experience is valuable because electrical projects vary by region, standard, language, application, and installation practice. A manufacturer serving many markets must develop flexible products and reliable support systems.

The company’s mission is to create value for customers and grow together with partners. Its professional technical support and after-sales service teams support customers through selection, integration, and operation. For a product such as a multi-function panel meter, technical support can be important during CT ratio setup, communication configuration, alarm settings, and system integration.

The company’s product portfolio also strengthens customer support. Since it manufactures electricity meters, power analyzers, current sensors, communication modules, and management systems, it can understand the full measurement chain. This helps when customers need not only a meter, but also a complete energy measurement solution.

Design Philosophy: Compact, Accurate, Connected, and Practical

The Smart X96-5G reflects a design philosophy based on four practical principles: compact installation, accurate measurement, connected data, and practical automation.

Compact installation is achieved through the standard 96 mm by 96 mm format, panel mounting design, and convenient connection approach. Accurate measurement is supported by Class 0.5S active energy performance, RMS measurement including harmonics, and defined accuracy for voltage, current, frequency, power, power factor, and THD. Connected data is provided through RS485 Modbus RTU. Practical automation is supported by digital inputs, digital outputs, alarm parameter settings, and SOE recording.

This combination makes the product suitable for modern electricity distribution because it addresses both traditional and emerging requirements. Traditional panels need meters that show voltage, current, power, and energy. Modern panels also need communication, event data, harmonic insight, and integration with automation systems. This product provides both.

Selection Considerations

When specifying this meter, engineers should confirm the electrical system type, CT ratio, voltage range, auxiliary power supply, communication network design, digital input and output requirements, and panel cut-out arrangement. The rated current input is 5 A, so it should be paired with suitable current transformers. The measured voltage range should be matched to the actual system configuration, including whether the network is 3P3W or 3P4W.

Communication planning should consider RS485 cable type, shielding, grounding practice, bus topology, termination, device addressing, baud rate, and compatibility with the master system. Alarm parameters and digital output functions should be configured according to the operational strategy. If multi-tariff analysis is required, the real-time clock option should be considered.

For best performance, installation should be carried out by qualified electrical personnel following applicable local standards and project requirements. CT polarity, voltage phase order, communication wiring, and auxiliary supply wiring should be carefully checked during commissioning. Correct setup ensures that the meter’s advanced functions provide reliable data.
