2pcs DC 12V 2 Channel Relay Module with Isolated Optocoupler High and Low Level H/L Level Trigger Module Triggered by DC 12V

Description :

1. The module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A;

2. The power indicator (green) , relay status indicator (red)

3. Module size : 50mm * 26mm * 18.5mm (L * W * H)

4. Has four mounting bolts holes , hole 3.1mm, 44.5mm * 20.5mm pitch

Module Interface:

1. DC +: positive power supply DC 12V

2. DC-: negative power connection

3. IN1: 1 channel signal to trigger the end , you can set a high or low level control relay

4. IN2: 2 -channel signal to trigger the end , you can set a high or low level control relay

Relay Outputs:

1. NO1: After a relay normally open interfaces , relay before floating, shorted pull with COM1

2. COM1: 1 relay common interface

3. NC1: 1 relay normally closed port, COM1 relay shorted before and after the pull- vacant

4. NO2:way normally open relay interface, the relay before floating , pull back and COM2 short

5. COM2: 2 Common Interface relay

6. NC2: 2 -way normally closed relay interface relay short front and COM2 , pull vacant post

Note:

This relay will be triggered by DC 12V, can not trigger with the arduino signal at 5V.
