Introduction to working principle: The relay is the core of the module, which is equivalent to an electromagnetically controlled switch. The 12V power supply terminal controls the on and off of the relay; 1. 12V power supply, the contact is closed, the strong current circuit is energized, and the equipment starts to work. 2. When 12V is disconnected, the contact is disconnected, the strong current circuit is cut off, and the equipment stops working.

Is the 12V power supply terminal used? Use your own existing control circuit module and directly connect to the 12V power supply terminal; If you use this product to control heating or cooling equipment, it is recommended to buy the W1308 thermostat from our store for use. Those who need to control the device through the time can purchase the M196 time control switch module from our store for use;
