Qingjun presents the Huaqingjun 12-Channel RS485 Ethernet AC Current Voltage Transformer Detect Module, a versatile and reliable acquisition module designed to simplify and enhance electrical monitoring in industrial, commercial, and utility settings. Built to meet practical needs, this module blends precise measurement, flexible communication, and robust design to deliver consistent performance in a wide range of applications

Core Functionality

The Huaqingjun 12-Channel module measures AC current and voltage through compatible current transformers (CTs) and potential or voltage transformers (PTs). With twelve input channels, it supports simultaneous acquisition from multiple circuits, feeders, or monitoring points. The module captures real-time electrical parameters and converts analog signals into precise digital data, making it well suited for energy monitoring, power quality analysis, load management, and preventive maintenance

Reliable Measurement and Accuracy

Designed for dependable field use, the module provides stable, accurate readings across all channels. It supports standard transformer inputs and is engineered to reduce noise and interference, ensuring trustworthy data even in electrically noisy environments. The module’s measurement circuitry maintains linear response and consistent accuracy over time, so users can rely on the data for billing, diagnostics, and operational decision-making

Flexible Communication: RS485 and Ethernet

The Huaqingjun module offers dual communication options to fit diverse network architectures. It supports RS485 with the Modbus RTU protocol, a proven standard for industrial control systems, allowing easy integration with PLCs, data loggers, and SCADA systems. For Ethernet-enabled networks, the module supports Modbus TCP, enabling seamless connection to modern control and monitoring platforms, remote servers, and building management systems. The dual-mode approach gives users the flexibility to connect in the way that best suits their infrastructure

Modbus RTU and Modbus TCP Compatibility

Interoperability is a key feature. The module adheres to Modbus RTU over RS485 and Modbus TCP over Ethernet, ensuring compatibility with a wide array of third-party software and hardware. This makes it straightforward to pull measurements into energy management systems, third-party monitoring dashboards, or custom applications. Standard Modbus registers expose current, voltage, and derived parameters, facilitating straightforward data retrieval and integration into existing workflows

Easy Installation and Wiring

The Huaqingjun module is designed for practical installation. Clear terminal labeling and a compact layout simplify wiring of CTs, PTs, power supply, and communication lines. The module’s form factor fits typical control cabinets and enclosures, while its screw terminals provide secure, vibration-resistant connections. This reduces installation time and lowers the risk of wiring errors, allowing technicians to deploy the module quickly and confidently

Scalable Monitoring

With twelve channels in a single unit, the module serves as a scalable building block for larger monitoring setups. Multiple modules can be networked together to expand monitoring coverage across multiple panels, floors, or meters. Whether monitoring a small plant or a large facility, the Huaqingjun module helps implement a phased, cost-effective rollout of energy monitoring infrastructure

Robust Industrial Design

Built to withstand demanding conditions, the module features a durable housing and industrial-grade components. It is suitable for control cabinet environments and can handle typical industrial temperature ranges and electrical stresses. Protective design elements help guard against transient surges and reduce susceptibility to electromagnetic interference, enhancing long-term reliability

User-Friendly Configuration and Diagnostics

The module includes straightforward configuration options for network settings, Modbus parameters, and channel calibration. Users can set communication modes, addresses, and data formats to match their system requirements. Diagnostic features help verify channel connectivity and detect common issues quickly, aiding commissioning and troubleshooting. Clear status indicators provide immediate visual feedback on power and communication health

Wide Range of Applications

The Huaqingjun 12-Channel RS485 Ethernet AC Current Voltage Transformer Detect Module is suitable for many applications

- Energy management and sub-metering in commercial buildings

Cost-Effective Data Collection

By consolidating 12 channels into a single module, the Huaqingjun product reduces the need for multiple discrete sensors and converters. This consolidation lowers material and installation costs while simplifying monitoring system architecture. The dual communication support helps avoid costly protocol converters and makes full use of existing network infrastructure

Safety and Compliance

The module incorporates standard safety features to protect both equipment and personnel. Proper isolation between measurement inputs and communication interfaces reduces the risk of accidental damage or hazardous conditions. The design follows common industrial safety conventions to ensure safe operation within typical electrical environments

Support and Documentation

Qingjun provides technical documentation to help with installation, configuration, and integration. Clear wiring diagrams, Modbus register maps, and configuration guides assist electricians, engineers, and integrators in deploying the module efficiently. Technical support from Qingjun helps resolve application-specific questions and aids in system setup

The Qingjun Huaqingjun 12-Channel RS485 Ethernet AC Current Voltage Transformer Detect Module is a practical, dependable, and flexible solution for multi-point electrical measurement. Its combination of accurate measurement, dual communication modes (Modbus RTU and Modbus TCP), easy installation, and industrial robustness make it a strong choice for energy monitoring, industrial control, and power management projects. Whether used as a standalone monitoring unit or as part of a larger networked system, this module helps deliver reliable electrical data to support smart decision-making and efficient energy use
