5v 8 Channel Relay Module Relay Board Relay Arduino Relay Module

5v 8 Channel Relay Module Relay Board Relay Arduino Relay Module contains eight 5V relays and the associated switching and isolating components, which makes interfacing with a microcontroller or sensor easy with minimum components and connections. Each relay on the board has the same circuit, and the input ground is common to all eight channels.

Eight-Channel Relay Module Basic Troubleshooting

If either of the relays does not turn on:

1. The contacts might be welded due to overcurrent/arcing. Shaking the module firmly might help unstick the contacts.
2. The driver circuitry might have been damaged due to overvoltage.
3. Input polarity might be incorrect.
4. Jumper might not have been moved to the correct position
