YINGHUA Pi Pico Relay Module Industrial 8-Channel Relay Module

SKU CH-29VB-ERW9S

An 8-channel relay module designed for Raspberry Pi Pico industrial control applications

  • 8-channel relay board expands Pi Pico I/O for industrial switching
  • Opto-isolated inputs protect the microcontroller from high-voltage transients
  • Terminal-block connectors simplify field wiring without soldering
  • Compact DIN-rail footprint fits standard control cabinets

Pi Pico 8-Channel Relay Module

This industrial relay module provides eight independently controlled channels for a Raspberry Pi Pico. It enables the microcontroller to switch higher-voltage or higher-current loads such as motors, heaters or lighting circuits. The board is intended for automation, test rigs and custom control panels where multiple isolated outputs are required.

Check Pico header alignment and load ratings

Verify that your Pico’s GPIO pinout matches the module’s header layout before mounting. Confirm each relay’s maximum switching voltage and current against the devices you plan to drive. Ensure your power supply can deliver enough current for all eight coils operating simultaneously.

Questions about this item

Does the 8-channel relay module include a Raspberry Pi Pico board or must it be purchased separately?

The module is designed to work with a Raspberry Pi Pico which is not included and must be bought separately.

Should I choose this 8-channel version or a module with fewer channels for my project?

Choose the 8-channel version when you need to switch up to eight independent circuits from one Pico; pick a smaller module if you only control one to four loads.
