  NO : Relay normally open contact
  COM : Relay common contact
  NC : Relay normally closed contact
  Momentary : Mobile terminal input "A0" (B0 / C0 / D0 is the same), the relay is "open",and after delay of 1 second the relay is "Close".
  Self-locking : Mobile terminal input "A1", the relay is "Open", input "A1", the relay is "Close", and so on
  Interlock : Mobile terminal input "A2", relay 1 is "Open", the other relay is "Close"; input
  
  
  
  
  B2", relay 2 is "Open", the other relay is "Close", and so on.

  Open : NO connection COM, NC disconnect COM

  Close : NO disconnect COM, NC connection COM
