Modbus RTU Relay (E) is a reliable relay module with an RS485 interface for use in industrial automation systems, remote control, HVAC, lighting, and energy management systems. It supports control of up to 8 relays rated at 30 A with full galvanic isolation and addressable function, enabling easy integration into complex serial communication installations.
Description
Industrial relay module with 8 channels controlled via RS485 bus using the Modbus RTU protocol. Equipped with high-current relays (up to 30 A) and multilayer protections such as galvanic isolation, opto-isolation, surge and short-circuit protection, ensuring stable, reliable, and safe operation in industrial automation applications.
Supports configurable device addressing (1–255), cascading of multiple modules in a single RS485 network, and timed relay switching mode. The built-in voltage regulator supports a wide input range of 7–36 V. Communication via RS485 with support for multiple baud rates and data formats. Housed in an ABS enclosure adapted for DIN rail mounting to facilitate integration into industrial installations.
