4 Channel 5V relay with Optcoupter , each Channel can cutover high/low Level

A module description :
1, the module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A;
2, using SMD optocoupler isolation , driving ability , stable performance ; trigger current 5mA;
3, the module voltage is 5V, 9,12 V, 24V are available ;
4 , each way module can be set high or low triggered by jumper ;
5 , fault-tolerant design , even if the control line is broken , the relay will not operate ;
6 , the power indicator ( green ) , 4 relay status indicator ( red )
7 , interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient
8 , module size : 73mm * 50mm * 18.5mm ( L * W * H )
9 , has four mounting bolts holes , hole 3.1mm, 67mm * 44.5mm pitch
Two module interface :
1, DC +: positive power supply ( voltage required by the relay , there 5V.9V.12V and 24V choice )
2, DC-: negative power connection
3, IN1-IN4: each way based on the settings , can be high or low to control the corresponding relay
Relay outputs : a 12- line interface, the interface can be directly connected to all leads , user-friendly
1, NO1 - NO4: normally open relay interfaces , relay before the vacant after the pull shorted with COM
2, COM1 - COM4 Common Interface Relays
3, NC1 - NC4: normally closed relay interface relay shorted with COM ago , after the pull- vacant

High and low trigger selection ends :

1.S1-S4 in order to relay a way -4 road 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
