Raspberry Pi Expansion Board Power Relay

Overview

The RPi Relay Board gives your Pi the ability to control high voltage/high current devices, easily makes normal home appliances become intelligent.

RPi Relay Board Features

• Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
• High quality relays, loads up to 5A 250V AC or 5A 30V DC
• Photo coupling isolation, prevent interference from high voltage circuit
• Onboard LEDs for indicating relays status
• Relay control jumper, allows to control the relays by custom pins other than the default pins
• Comes with development resources, including examples in wiringPi, WebioPi, shell, python, and bcm2835

What's on the RPi Relay Board

2. Relay screw terminal:for connecting target devices
3. Relays
4. Photocoupler:PC817
5. Relay indicator
   • LED on: relay NC is opened, NO is closed
   • LED off: relay NC is closed, NO is opened
6. Power indicator
7. Relay control jumper
   • short the jumper: control the relays by default I/Os used in the example code
   • open the jumper: control the relays by custom I/Os through jumper wires
