Industrial 4-Channel Relay Module

The module leverages the standard Modbus RTU protocol, offering seamless integration with RS485 or RS232 communication interfaces. It's engineered to support an array of communication baud rates ranging from 2400 to 38400, with a default setting of 9600. This facilitates the smooth operation of the relay module within a wide spectrum of industrial environments.

Designed for versatility, each relay output operates independently and can connect to a variety of load devices, including 24V solenoid valves. It effortlessly handles both AC and DC devices, presenting a robust solution for diverse applications. The system's design ensures isolation for each relay output contact and allows setting device addresses ranging from 0 to 255, promoting efficient device management and operation.

This 4-channel relay module transforms a single computer serial port into a powerful control center for your electrical equipment. It supports an expansive DC7-30V wide voltage power supply, with built-in optocoupler isolation that ensures secure and reliable connections. The module accommodates four-way switching input and output, making it a dynamic tool for controlling multiple devices simultaneously.

Perfectly suited for controlling electrical equipment from afar, this module finds application across numerous fields including factories, hotels, and lighting control in venues such as stages, homes, and cinemas. Additionally, it serves as an integral component in motor control and production line operations, exemplifying its multifunctional capabilities in varied settings.
