Description
The 4-channel relay module is designed to be used in industrial settings such as factories and hotels, as well as for lighting control in stages, homes, cinemas, and other settings. It can also be used for motor control and production line control. The module is equipped with the standard Modbus RTU protocol and supports both RS485 and RS232 communication interfaces. It has a baud rate of 9600 by default, but it can also support 2400, 4800, 19200, and 38400 baud rates. The relay module is capable of controlling both AC and DC devices, including 24V solenoid valves. Each of the four relay outputs is independent and can be connected to different loads. The contacts of each output are isolated and can be assigned device addresses ranging from 0 to 255. The module is designed to be controlled through a single computer serial port and supports a wide range of DC voltages (7-30V). It has optocoupler isolation and four-way switching input and four-way relay output.
