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, 9V,12V, 24V are available ;
4,The module can be set to 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 ) , relay status indicator ( red );
7,Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient;
8,Module size : 50mm * 26mm * 18.5mm ( L * W * H );
9,Has four mounting bolts holes , hole 3.1mm, 44.5mm * 20.5mm 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, 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 .

Package Included:

1 x Relay Module with Optocoupler
