Relay output:
1. NO1: 1 channel relay usually opens the interface. The relay is suspended before suction and short-connected with COM1 after suction.
2. COM1: 1 channel relay common Interface
3. NC1: 1 channel relay normally closed interface, short connection with COM1 before relay suction, suspension after suction
4. NO2: 2 channel relay often opens interface. The relay is suspended before suction, and is short-connected with COM2 after suction.
5. COM2: 2 channel relay common interface
6. NC2: 2 channel relay normally closed interface, short Connection with COM2 before relay suction, suspension after suction.
 
High and low level trigger selector:
1. S1 is the trigger selection of high and low level 1 channel relay.
2. S2 is the trigger selection of high and low level 2 channel relay.
3 and low short connection, the corresponding relay is low-level trigger, com and high short connection is high-level trigger.
