Package list:
1×Relay Module

Note:
Module interface:
1.DC+:Connect the positive pole of the power supply
2.DC-:Connect power supply negative pole
3.IN1:1 signal trigger terminal, can set high or low level control relay suction
4.IN2:2 signal trigger terminal, can set high or low level control relay suction

Relay output:
1.NO1: 1 channel relay usually opens the interface. The relay is suspended before suction and short-connected with COM1 after suction.
2.COM1:1 channel relay common Interface
3.NC1:1 channel relay normally closed interface, short connection with COM1 before relay suction, suspension after suction
4.NO2:2 channel relay often opens interface. The relay is suspended before suction, and is short-connected with COM2 after suction.
5.COM2:2 channel relay common interface
6.NC2:2 channel relay normally closed interface, short Connection with COM2 before relay suction, suspension after suction.

High and low level trigger selector:
1.S 1 is the trigger selection of high and low level relay.
2.S2 is the trigger selection of 2-way relay at high and low levels.
3.com and low short connection, the corresponding relay is low-level trigger, com and high short connection is high-level trigger.
