The PiRelay 8 is a relay expansion board for the Raspberry Pi that can control up to 8 devices with photo-coupling isolation, with loads up to 250V AC/7 A, 30V DC/10 A, and a trigger voltage of 3.3V. It allows you to safely control high voltages or high-current devices.

It has enough space for the 4.3" LCD to fit comfortably, allowing the user to operate the device with ease. One of the best features of the PiRelay 8 board is the 5 V/2A USB power port. It supplies power to the Raspberry Pi straight through the Pirelay 8 board.

In a simplified way, PiRelay 8 channel is a set of eight relays with an optocoupler that uses light energy to safely send an electrical signal between two separated circuits.

If you're looking for a more compact solution or don't need this many relays, check out the PiRelay 6 or have a look through our relay HAT section.
