12V 2 Channel Solid State Relay Module, Low Level Trigger, 5A DC Control for Raspberry Pi

Product description Trigger voltage 5V low level trigger module: 0-1. 5VDC relay is turned on (ON), 3-5VDC Relay off (OFF) 12V low level trigger module: 0-4. 5VDC relay on (ON), 5. 5-12VDC relay off (OFF) 24V low level trigger module: 0-8. 5VDC relay connected (ON) 10-24VDC relay disconnected (OFF) The relay is controlled by the terminal A and B port is just a switch. It should be noted that the A port is connected to the positive pole of the power supply, and the B port is connected to the positive pole of the required equipment. If A and B are connected reversely, the relay will not be controlled!
Note: The CH terminal is the trigger terminal of the module. When there is a trigger signal, the output switches (A, B) of the solid state relay will be closed, and the load will be turned on.
