WaveShare Raspberry Pi 8-Channel Relay Module Expansion Board

The RPi Relay Board by Waveshare is an expansion board with 8-channel relay for Raspberry Pi. With the relay board you can control 12V water valves to realise an automatic irrigation. You can also control other consumers up to a current of 5A.
For safety reasons, we recommend that you only operate the relays up to 30V.

Properties Raspberry Pi relay card:
Compatible Raspberry Pi A+/B+/2B/3B/3B++/4B/4B+.
High quality relays for switching loads up to 5A 250V AC or 5A 30V DC
Optocoupler for optimal protection of the Raspberry
