Huaqingjun 6-Channel RS485 LAN Current Voltage Transformer Detect Module Detection Modbus RTU TCP Acquisition Module

Qingjun Huaqingjun 6-Channel RS485 LAN Current Voltage Transformer Detect Module is a reliable, easy-to-use acquisition module designed for accurate monitoring of multiple electrical signals in industrial, commercial, and residential settings. Built for compatibility with Modbus RTU and Modbus TCP protocols, this module offers flexible communication options via RS485 and Ethernet LAN, making it a practical choice for system integrators, engineers, and technicians who need clear, real-time data from current and voltage transformers

This compact, well-built module supports six independent channels, allowing simultaneous measurement of multiple circuits. Each channel can accept inputs from current transformers (CTs) or voltage transformers (VTs), enabling balanced measurement of three-phase systems or monitoring of separate single-phase loads. The design is aimed at delivering stable, precise readings of current and voltage signals so users can perform energy monitoring, power quality analysis, load balancing, and fault detection with confidence

Installation and wiring are straightforward. The module features clearly marked terminals for CT and VT inputs, power supply, and communication ports. RS485 terminals provide reliable serial connectivity for Modbus RTU networks, enabling daisy-chaining and long-distance communication over twisted pair cable. For networked environments and modern SCADA systems, the built-in Ethernet port supports Modbus TCP, allowing direct integration into LANs and remote monitoring over standard IP networks. This dual communication capability gives users the freedom to choose the protocol and topology that best suits their application

Qingjun focused on measurement accuracy and stability. The module uses well-matched input circuits and careful signal conditioning to minimize noise and error, providing consistent readings over a wide range of operating conditions. Configurable input ranges allow the module to work with common CT and VT specifications, and it supports both AC current and AC voltage measurement. The module’s sampling system and onboard processing translate analog inputs into digital values, which the device exposes through standard Modbus registers. This makes it easy to integrate with PLCs, data loggers, building management systems, and custom software using widely supported Modbus functions

Safety and durability are key considerations in the design. The front panel and terminal blocks are built to meet typical industrial safety standards, and the module is housed in a robust enclosure suited for DIN-rail mounting in electrical cabinets. Isolation between inputs, communication ports, and power supply reduces the risk of interference and protects connected equipment. The module’s components are selected for long-term reliability in typical industrial environments, and the device is designed to withstand the electrical stresses present in monitoring applications

Configuration is user-friendly. The module supports address setting for Modbus RTU networks and IP addressing for Modbus TCP, allowing quick deployment into new or existing systems. Many settings, such as sampling rate, filtering, and scaling factors for CTs and VTs, can be adjusted to match installation specifics. These options help ensure that the data returned by the module reflects the actual electrical quantities on site. When used with common SCADA or data acquisition software, the module’s standard Modbus register map allows rapid mapping of measurements into trending, alarming, and reporting functions

Real-time monitoring and historical data collection are made easy by the Qingjun Huaqingjun module. With responsive communication and reliable measurement, operators can view live current and voltage values, set thresholds for alarms, and track trends over time. This data is useful for preventive maintenance, energy management, billing accuracy, and identifying abnormal conditions such as unbalanced loads or unexpected voltage drops. The module helps reduce downtime by providing clear, actionable data that supports fast troubleshooting and informed decision-making

The module is designed with practical features that simplify maintenance and integration. LED indicators show power and communication status, helping technicians confirm correct operation at a glance. Robust terminal screws and clear labeling reduce wiring errors during installation or service. The compact DIN-rail form factor saves space in control cabinets and allows neat, modular layouts with other automation components

Qingjun provides clear documentation and a straightforward register map for developers and system integrators. This documentation includes wiring diagrams, communication examples, and configuration steps to help you get the module up and running quickly. Because it uses standard Modbus protocols, the module works with many off-the-shelf tools and software, reducing the need for custom drivers or special middleware

Applications for the Qingjun Huaqingjun 6-Channel RS485 LAN Current Voltage Transformer Detect Module span many sectors. In industrial plants, it is well-suited for monitoring motor circuits, feeders, and distribution panels. In commercial buildings, it supports energy metering and load management for HVAC, lighting, and tenant metering. Utility and substation environments can use the module for secondary monitoring and remote data collection. Renewable energy installations, such as solar farms, can benefit from its ability to monitor multiple inverters or strings for balanced output and fault detection

Performance, versatility, and ease of use make this Qingjun module a solid choice for projects that require dependable electrical measurement and networked data access. Its six-channel capability, dual Modbus communication, and thoughtful design provide a practical balance of functionality and simplicity. Whether you are building a new monitoring system or expanding an existing one, the Qingjun Huaqingjun 6-Channel RS485 LAN Current Voltage Transformer Detect Module offers a dependable solution for precise, network-ready current and voltage acquisition
