Modbus RTU 12V 8-Channel Relay Module – RS485 Industrial Relay Control Board
The Modbus RTU 12V 8-Channel Relay Module is an industrial-grade relay control board designed for reliable remote switching and automation through an RS485 communication interface. It features 8 independent relay channels and supports the Modbus RTU protocol, making it suitable for integration with PLCs, microcontrollers, industrial controllers, HMI systems, and automation platforms.
Powered by 12V DC, the module allows connected electrical loads to be controlled through RS485 commands over longer communication distances. Each relay channel can be independently addressed and controlled, providing a practical solution for industrial automation, equipment control, lighting systems, pumps, motors, and other electrical switching applications.
Its compact design and screw-terminal connections make wiring convenient for control panels and embedded automation projects. The RS485 interface provides a robust communication method for multi-device networks, while the 8-channel relay configuration enables centralized control of multiple loads from a single module.
