Description :
1. The module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A;
2. The power indicator (green) , relay status indicator (red)
3. Module size : 50mm * 26mm * 18.5mm (L * W * H)
4. Has four mounting bolts holes , hole 3.1mm, 44.5mm * 20.5mm pitch

Module Interface:
1. DC +: positive power supply DC 12V
2. DC-: negative power connection
3. IN1: 1 channel signal to trigger the end , you can set a high or low level control relay
4. IN2: 2 -channel signal to trigger the end , you can set a high or low level control relay

Relay Outputs:
1. NO1: After a relay normally open interfaces , relay before floating, shorted pull with COM1
2. COM1: 1 relay common interface
3. NC1: 1 relay normally closed port, COM1 relay shorted before and after the pull- vacant
4. NO2:way normally open relay interface, the relay before floating , pull back and COM2 short
5. COM2: 2 Common Interface relay
6. NC2: 2 -way normally closed relay interface relay short front and COM2 , pull vacant post

This relay will be triggered by DC 12V, can not trigger with the arduino signal at 5V.
Package Included:
2*DC 12V 2 Channel Relay Module With Isolated Optocoupler High and Low Level Trigger

Can set high or low level trigger with jumper, to meet the demand of more trigger applications;
With patch optical isolation, strong drive ability and stable performance;
The module can be high or low by a jumper setting trigger;
Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient ;
Fault-tolerant design , even if the control line is broken , the relay will not operate ;
