Description

Industrial relay module with four channels, designed for RS485 communication using the Modbus RTU protocol. It supports high-current relay control (up to 30 A), and thanks to numerous built-in protection circuits – such as galvanic isolation, resettable fuse, TVS diode, and reverse polarity protection – it ensures high reliability, noise immunity, and operational safety in industrial environments. A configurable device address and support for various baud rates allow integration with a wide range of control systems.
