Modbus RTU Relay 4CH is a reliable industrial-grade relay module supporting RS485 communication with the Modbus RTU protocol. With the ability to handle high currents and a wide power supply voltage range, it is well-suited for lighting control systems, industrial automation, HVAC installations, and remote monitoring applications. Built-in protection circuits and DIN rail mounting enhance safety and facilitate integration into control cabinets.
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.
