Slice of Relay Raspberry Pi (B047) Relay board for Raspberry Pi

The Slice of Relay is a fully assembled add on board for the Raspberry Pi computer. It has 2 high power relays for switching external electrical circuits. The board plugs directly into the Pi’s 26 way GPIO header and is controlled by two I/O pins. The pins can be altered to any other if desired by removing the red jumpers and wiring elsewhere.

The product is available with either 10 amp or (by special arrangement) 16 amp relays. The rating is marked on the body of the relay. The relays are rated at up to 250v AC.

MAINS USE should NEVER be attempted by anyone unfamiliar, not competent and not qualified. The whole board including Pi should be enclosed in an isolated enclosure. We accept no responsibility for misuse at any voltage, including mains. MAINS CAN KILL!

If you need to expand your GPIO header to support another connection, there are a second row of holes which you can solder to.

Features:

• 2 high power relays
• 10 amp or 16 amp versions (by special arrangement, built to order)
• Up to 250v AC (see safety warning)
  
• Economical
• LED indicators for both relays
• Can be run from any GPIO pinOn board if desired

Applications:

• Switching large loads
• Web control of devices (berryIO is good example and worth a look) http://frozenmist.co.uk/downloads/berryio/
• Timer requirements
• Automation
• Irrigation
• Prototyping

Really eay to use, see pdf for full details, here's the code needed for Python to turn on Relay A (simples!)

import wiringpi2 as wiringpi 
wiringpi.wiringPiSetup() 
wiringpi.pinMode(5,1)
wiringpi.digitalWrite(5,1)
