Raspberry Pi 3-Channel Relay Module Expansion Board

The RPi Relay Board from Waveshare is an expansion board with a 3-channel relay for the Raspberry Pi. With the relay card, you can control 12V water valves to realize automated irrigation. However, you can also control other devices with a current intensity of up to 5A.

For safety reasons, we recommend operating the relays up to a maximum of 30V.

Features Raspberry Pi Relay HAT:

• 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 the Raspberry
• Onboard LEDs for relay status display
• Jumper for the selection of relay control pins, allows the control of the relays through custom pins that differ from standard pins.
• Reserved control interface allows working with controls such as PLC
• Program examples for wiringPi, bcm2835, and python
