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.
