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.
