2 way: 50*41*17.5MM

4 way: 75*51*16.5MM

8 way: 142*52*18MM

Module interface:
1. DC+: connect to the positive pole of the power supply (voltage according to the requirements of the relay)
2. DC-: Connect to the negative pole of the power supply
3. IN: can control the relay to close
Relay output:
1. NO: The relay is normally open interface, the relay is suspended before it is closed, and it is short-connected to COM after it is closed.
2. COM: relay common interface
3. NC: Normally closed interface of the relay, the relay is short-connected with COM before it is closed, and it is suspended after it is closed

High and low level trigger selection terminal:

1. When the jumper is shorted to LOW, it is low level trigger;
