  • Information

The module adopts the standard Modbus RTU protocol, the communication interface supports RS485 or RS232 and supports communication baud rates of 2400, 4800, 9600, 19200, 38400 (default 9600). Each relay output is independent and can be connected to different load devices, such as 220V electric lights, 24V solenoid valves, etc. Both AC and DC devices can be controlled. Each relay output contact is isolated and can set 0-255 device addresses. It can be switched on and off very quickly. This industrial 4-channel relay module allows you to control your electrical equipment only through one computer serial port. It supports DC7-30V wide voltage power supply, optocoupler isolation, four-way switching input, and four-way relay output. The management and controlling of electrical equipment can be completed by a computer, which makes this module able to be widely used in scenarios like factories, hotels, etc., as well as lighting control in stages, homes, cinemas, etc., and can also be used for motor control, production line control, etc.
