Raspberry Pi 8-Channel Relay Module Expansion Board

The RPi Relay Board by Waveshare is an expansion board with an 8-channel relay for Raspberry Pi. With the relay card, you can control 12V water valves to implement automatic irrigation. But you can also control other consumers up to a current of 5A.

For safety reasons, we recommend operating the relays only up to 30V.

Features Raspberry Pi Relay Card:

• Compatible with Raspberry Pi A+/B+/2B/3B/3B/3B++/4B/4B+
• High-quality relays for switching loads up to 5A 250V AC or 5A 30V DC
• Optocouplers for optimal protection of Raspberry
• Standard DIN rail mounting
• Onboard LEDs for displaying the relay status
• Jumper for selecting the relay control pins, allows the control of the relays through custom pins, differing from the standard pins.
• Reserved control interface, allows working with controls such as PLC
• Program examples for wiringPi, bcm2835, python, python, python-bottle (website control) and crontab (cron job)
