8-ch Relay Expansion Board for Raspberry Pi

An 8-channel relay expansion board designed for Raspberry Pi, capable of switching high-power AC and DC loads. Features photo-coupler isolation between the Pi's GPIO and the relay circuits for safe, reliable operation.

Includes a DIN rail mount case for professional installations. The board can be cut along marked lines to reduce size if fewer channels are needed.
