Module Interface :

1. DC +: 12V positive power supply

2. DC-: negative power connection

3. IN1-IN8: each way based on the settings , can be high or low to control the corresponding relay

Relay outputs :

1. NO1 - NO8: normally open relay interfaces , relay before the vacant after the pull shorted with COM

2. COM1 - COM8: Relay Common Interface

3. NC1 - NC8: normally closed relay interface relay shorted with COM ago , after the pull- vacant

High and low trigger selection :

1.S1-S8 in order to relay a road -8 way high and low trigger selection ;

2.Com with low short circuit , triggering the corresponding relay is low , while the high end of the short com high trigger
