Industrial 8-Channel Relay Module for Raspberry Pi Pico

Utilise the Raspberry Pi Pico in industrial or home automation environments with this robust Industrial 8-Channel Relay Module!

This module provides 8 relay channels which can each switch up to 10A 250VAC or 10A 30V DC max. The module offers safety in the form of onboard unibody power supply isolation combined with photocoupler isolation to prevent interference. The custom ABS enclosure protects both user and hardware, and provides DIN and screw mounting options.

Your Raspberry Pi Pico slots into the dedicated female headers and is programmed via the micro-USB port on the side of the board (connected to the Pico via Pogo pins) which is accessible once the enclosure is assembled. A handy boot and rest button are also found here, alongside a programmable buzzer, RGB LED and power LED.

Each relay also has its own LED indicator, showing the status of the relay.

Note: Raspberry Pi Pico not included. You’ll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.
