2. DC-: connect to the negative pole of the power supply
3. IN: The relay can be controlled at low levenl to pull in
4. VCC external 3V
5. GND External GND

Relay output
1.NO: The relay is normally open interface, the relay is suspended before it is closed, and it is short-circuited with COM after it is closed.
2. COM: relay common interface
3.NC: Relay normally closed interface, short-circuit with COM before the relay is pulled in, and vacant after the pull-in
