RS485/Modbus communication module SM103E SM211

Communication module RS485/Modbus – expanding installation capabilities

This communication module, designated SM211, is a key element in energy monitoring and management systems. It enables the integration of Hager devices with networks based on the Modbus RTU protocol via the RS485 interface. This allows for reading data and remote control of connected devices, which translates into greater energy efficiency and cost optimization.

Functionality and application

The SM103E module expands the functionality of measurement and control systems, enabling the collection of data from various points in the installation. It is particularly useful in commercial buildings, industrial facilities, and applications requiring remote access to energy consumption information. Installers will appreciate the ease of integration with existing Modbus systems, and end-users will benefit from access to detailed network parameter data.

Construction features and operating parameters

The module is characterized by compact dimensions (84 mm height, 21 mm width, and 36 mm depth), which facilitates mounting in switchboards. It is adapted to operate in a wide temperature range – from -10°C to 55°C – ensuring reliability even in harsh conditions. The connectors used allow for the connection of flexible and rigid wires with a cross-section of 0.5 to 1.5 mm². The IP20 protection class provides basic protection against contact. The rated insulation voltage is 4000 V, which guarantees safe use.
