8-Channel Relay Expansion Board for Raspberry Pi

The 8-Channel Relay Board is an expansion board with relays which has been designed specifically for the Raspberry Pi. It gives your Pi the ability to control lots of high-voltage components (such as home appliances) to create a full home automation system. The relays are rated at 5A 250V AC or 5A 30V DC (Max) and feature photo-coupling isolation to reduce interference. Onboard LEDs indicate each relay's status for visual indication and debugging support. The board comes in a frame ready to fit into DIN rails if desired. Features

* Standard Raspberry Pi 40-pin GPIO extension header * 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 the user to control the relays by custom pins other than the default pins * Reserved control interface allows the board to work with controllers like PLC * Comes with development resources and guide
