DC 12V 2 Channel Relay Module With Isolated Optocoupler High and Low Level H/L Level Trigger Module for Arduino -NA189

1. Size: 50.5 x 38.5 x 18.5mm (length x width x height)
2. Weight: 31g
3. PCB color: Black
4. There are 4 fixing screw holes around the board, the hole diameter is 3.1mm, which is convenient for installation and fixing.
5. Relay with a common end, a normally open end, and a normally closed end
6. Optocoupler isolation, good anti-interference
7. Low level pull-in, high level release. The status indicator is on when the inverter is closed, and the status indicator is off when released.
8. VCC is the system power supply and JD_VCC is the relay power supply, use with the jumper cap
