Description Waveshare Industrial 8-Channel Relay Module for Raspberry Pi Pico is an industrial relay expansion board designed around the Raspberry Pi Pico form factor. It provides 8 relay channels, supports high-current AC and DC switching, and is built for automation, industrial control, and multi-load switching tasks. This module is especially useful when you need a compact relay controller with stronger protection and enclosure design than a basic hobby relay board. It includes photocoupler isolation, power supply isolation, and an ABS protection enclosure, which makes it a more practical fit for industrial environments and control cabinets. Features 8 relay channels for multi-load control. Supports up to 10A 250V AC or 10A 30V DC relay switching. Photocoupler isolation for improved control-side protection. Power supply isolation for more reliable industrial use. ABS protection enclosure for safer and cleaner installation. Rail-mount design suitable for control cabinets and industrial setups. Compatible with Raspberry Pi Pico header layout. Good fit for automation, industrial switching, and multi-device relay control.

Embedded relay controller projects that need better protection and enclosure design. Product List Industrial 8-Channel Relay Module for Pico ×1 ABS protection enclosure ×1 Rail-mount related hardware ×1 set Other Content The main reason to choose this board over a generic 8-channel relay shield is its industrial protection-oriented design. The combination of photocoupler isolation, power isolation, and enclosed rail-mount form factor makes it much easier to use in more demanding electrical control scenarios. It is also a practical option when you want to keep the Raspberry Pi Pico ecosystem for logic control, but need a relay board that feels closer to industrial hardware than a loose bare relay module. That makes it suitable for control cabinets, equipment switching, and longer-term fixed installations.
