The Boardoza CPC1945Y Breakout Board is built around the CPC1945Y AC Solid State Relay (SSR), providing safe, silent, and reliable switching of low-power AC loads. Thanks to its optically isolated input and zero-crossing detection structure, it enables noise-free AC switching directly from microcontroller systems.
This board is ideal for applications such as multiplexers, data acquisition systems, industrial control units, electronic meters (electricity, gas, water), medical devices, security systems, I/O subsystems, and as a compact and long-lasting solid-state replacement for mechanical relays. With no mechanical contacts, it ensures long operational life and vibration-resistant performance.
