Hager HTC320H komunikačný modul Modbus RTU RS485 pre elektromery

Integrating energy meters into a Modbus network often requires a dedicated interface to convert meter data into a standard protocol. The Hager HTC320H communication module solves this by providing a Modbus RTU interface over RS485, enabling seamless integration of compatible Hager energy meters into building management systems, PLCs, or SCADA systems.

Who is it for

This module is intended for electricians, panel builders, and facility managers who need to monitor energy consumption remotely. It is particularly useful in commercial and industrial buildings where multiple meters must be aggregated and read from a central controller.

Main features

• Modbus RTU protocol over RS485 interface
• Compatible with Hager energy meters such as JUPITER and ECR3xx series
• DIN rail mounting, 2 TE width (35 mm)
• Powered directly from the connected energy meter
• Configurable baud rate, parity, and stop bits
• LED indicators for RX/TX status

Tips

When installing, ensure the RS485 network is properly terminated and biased according to the Modbus standard. The module's address and communication parameters must be configured to match the master device. For best performance, use twisted-pair cable for the RS485 bus.
