Specification:

A. Module 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, 9,12 V, 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. Set four mounting bolts holes, hole 3.1mm, 44.5mm * 20.5mm pitch.

B. Module interface:

1. DC +: Connect with positive power supply (voltage required by the relay, you can choose 5V/9V/12V/24V ).

2. DC-: Connect with negative power.

3. IN: Can be high or low level control relay.

C. Relay output:

1.NO: Normally open relay interface, the relay before the vacant after the pull shorted with COM.

2.COM: Common Interface Relay.

3.NC: Normally closed relay interface relay shorted with COM ago, after the pull-vacant.

D. High and low level trigger selection ends:

1. When jumper short circuit with LOW is low lever trigger.

2. When jumper short circuit with high is high lever trigger.

E. Technical parameters:
