Raspberry Pi 8-Channel Relay Expansion Board

Overview

The RPi Relay Board (B) is an expansion board with 8-ch relays for Raspberry Pi. It gives your Pi the ability to control high voltage products such as home appliances.

Features

• Supports Raspberry Pi A+/B+/2B/3B/3B+
• High quality relays, loads up to 5A 250V AC or 5A 30V DC
• Photo coupling isolation, prevent interference from high voltage circuit
• Standard rail mount bottom case
• Onboard LEDs for indicating relays status
• Relay control pin selection jumper, allows to control the relays by custom pins other than the default pins
• Reserved control Interface, allows to work with controllers like PLC
• You can find all the documentation here, including examples in wiringPi, bcm2835, python, python-bottle (webpage control), and crontab (cron job)
