Relay output: 1, NO: relay normally open interface, the relay pull before the open, after the short-circuit with the COM 2, COM: relay common interface 3, NC: normally closed relay interface, the relay before the short circuit with the COM, pull after the vacant   Noun: Long lock: P1 port received a low level, the relay has been conductive until the module power, only closed. Self-locking: P2 port receives a low level, the relay conduction, once again received low, the relay is turned off. Delay 30s: P3 port received a low level, the relay turns on automatically after 30s, then received low, and then delay 30s
