1 Channel 12V Relay Module Board Shield With Optocoupler Support High And Low Level Trigger Power Supply Module For Arduino

The module uses a quality relay , normally open interfaces, Maximum load : AC 250V/10A, DC 30V/10A;
Uses SMD optocoupler isolation , driving ability , stable performance ; trigger current 5mA;
The module voltage is 12 V 
The module can be set to high or low triggered by jumper
Fault-tolerant design , even if the control line is broken , the relay will not operate 
Power indicator ( green ) , Relay status indicator ( red )
Interfaces can be connected directly via terminal wiring leads , very convenient
Module size : 50mm * 26mm * 18.5mm ( L * W * H )
Has four mounting bolt holes , hole 3.1mm, 44.5mm * 20.5mm pitch.
Two module interface :
1, DC +: Positive power supply ( voltage required by the relay , there 12V choice ); 2, DC-: Negative power connection; 3, IN: Can be high or low level control relay.
Relay outputs :
1, NO: Normally open relay interface, the relay before the vacant after the pull shorted with COM; 2, COM: Common Interface Relays; 3, NC: Normally closed relay interface relay shorted with COM ago , after the pull- vacant. High and low trigger selection ends : 1 short jumper with LOW LOW triggered when connected ;
2 When the jumper is high with high short trigger .
