12V 8 Channel Relay Module With OPTO-Isolated High And Low Level Trigger The module Operating voltage 12V; The module can be high or low by a jumper setting trigger; Fault-tolerant design, even if the control line is broken, the relay will not operate; The power indicator (green), the relay status indicator (red). 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 12V;
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 ) , 8 relay status indicator ( red )
7 . Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient
8 . Module size : 141.5mm * 50mm * 18.5mm ( L * W * H )
9 . Has four mounting bolts holes , hole 3.1mm, pitch 136mm * 44.5mm

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 :24 line interface, the interface can be directly connected to all leads , user-friendly
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

Package Included:
1*12V 8 Channel Relay Module With Optocoupler
