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 5Vare 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: Approx. 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 (VCC)( voltage required by the relay, 5V );

2. DC-: Negative power connection;(GND)

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.
