Description

This Relay module is a Raspberry Pi compatible module, no DuPont wire is needed. It has three relay channels on board, you can turn on/off the relay with sending a command to raspberry pi, or clicking a button by accessing the web page on raspberry Pi. With it, all the power is under control, you can easily make normal home appliances become intelligent.

Features

• Supports Raspberry Pi A+/B+/2B/3B
• High quality relays, loads up to 250VAC/5A, 30VDC/5A
• Photo coupling isolation, prevent interference from high voltage circuit
• On-board 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

1. Raspberry Pi GPIO interface: for connecting Raspberry Pi
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
