Industrial Control Made Simple
Meet the Pi-Plates RELAYplate: High-Power Switching Without the Pin Clutter
Take absolute control of high-voltage devices with the Pi-Plates RELAYplate, the ultimate stacking add-on board designed for seamless automation. Boasting seven heavy-duty relays capable of switching up to 120VAC or 30VDC, this board allows your projects to safely bridge the gap between low-voltage logic and real-world appliances. Whether you are automating home lighting, triggering industrial machinery, or building remote telemetry systems, this plate delivers rugged, dependable power control right out of the box.
What truly sets the RELAYplate apart is its intelligent, hardware-saving architecture. Instead of burning seven individual microcontroller pins to control seven relays, it leverages a high-speed SPI bus to manage everything over just two dedicated digital lines. This efficient design allows you to stack up to eight boards on top of each other, giving you a massive matrix of up to 56 independently controlled relays without sacrificing your host board's precious IO. Equipped with built-in surge protection, clear LED status indicators, and an easy-to-use software library, it is the professional-grade solution your next automated system deserves.
