Package List: 1 Relay Module

Note: Module Interface: 1. DC+: Connect to the positive terminal of the power supply 2. DC-: Connect to the negative terminal of the power supply 3. Signal Trigger Terminal IN1: 1, can adjust the activation of the level control relay to high or low 4. Signal Trigger Terminal IN2: 2, can adjust the activation of the level control relay to high or low Relay Output: 1. NO1: The 1-channel relay interface is usually open. The relay is suspended before activation and short-circuited with COM1 after activation. 2. COM1: 1-channel relay common interface. 3. NC1: 1-channel relay normally closed interface, short connection with COM1 before the relay is activated, suspended after activation. 4. NO2: 2-channel relay often open interface. The relay is suspended before activation and short-connected with COM2 after activation. 5. COM2: 2-channel relay common interface. 6. NC2: 2-channel relay normally closed interface, short connection with COM2 before the relay is activated, suspended after activation. High and low level trigger selector: 1. S1 is the high and low level trigger selection for the 1-channel relay. 2. is the high and low level trigger selection for the 2-channel relay. 3. COM and short connection short: the corresponding relay is a low level trigger; COM and short connection high: the corresponding relay is a high level trigger.
