Function Description:
NO : Relay normally open contact
COM : relay common contact
NC : Relay normally closed contact
''Open'' :The NO connects to the COM, and the NC disconnects the COM
''Close'' :The NO disconnects the COM, and the NC connects to the COM
Crawl :Enter the tap command, with the relay ''on'' and ''off'' after 600 ms
Auto-lock :Enter the self-lock command, the relay ''on'', enter the self-lock command again, the relay ''off'', and so on
delay :Input the delay command, the relay ''turns on'', after waiting for the set time, the relay ''turns off''; during the delay period, after the turn-off command is input, the relay turns off immediately
