The module adopts the Modbus RTU protocol standard, the communication interface supports RS485 or RS232 and supports baud rates of 2400, 4800, 9600, 19200, 38400 (default 9600). Each relay output is independent and can be connected to various load devices, such as 24V solenoids. Both AC and DC devices can be controlled. Each relay output contact is isolated and can be set to device addresses 0-255. Fast activation and deactivation are possible. This industrial 4-channel module allows for the control of electrical devices through a single serial computer connection port. It supports a wide DC power supply range of 7-30V, opto-isolation, four-way input, and four-way relay output. The management and control of electrical devices can be completed via a computer, making this module widely used in scenarios such as factories, hotels, etc., as well as in lighting control in scenes, homes, cinemas, etc., and can also be used for motor control, production line control, etc.
