Relay 12V 1 Channel with Optocupler for Arduino

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 Operating voltage 12V;

4. the module can be high or low by a jumper setting trigger;

5. fault-tolerant design, even if the control line is broken, the relay will not operate;

6. the power indicator (green), the relay status indicator (red)

7. the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient

8. module size: 50mm*26mm*18.5mm (L*W*H)

Module interface: 

1. DC+: positive power supply (VCC)

2. DC-: negative power supply (GND)

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

Relay outputs: 

1. NO: normally open relay interface

2. COM: Common Interface Relays

3. NC: normally closed relay interface

High and low level trigger options: 

It is low level trigger when jumper connect to LOW pin

It is high level trigger when jumper connect to HIGH pin
