7Semi Single Channel Solid State Relay Zero-cross Module | 5V Logic Input | 240VAC 2A Output

The 7Semi Single Channel Solid State Relay (SSR) Module is a compact, high-reliability AC load switching module based on the Panasonic AQG22105 PhotoMOS Solid State Relay. Designed for seamless interfacing with 5V microcontrollers, this module enables silent, fast, and maintenance-free switching without mechanical contacts.

Unlike conventional electromechanical relays, the AQG22105 uses optically isolated MOSFET technology, eliminating contact wear, bounce, and switching noise while providing excellent electrical isolation and long operational life. It is ideal for industrial automation, embedded control systems, IoT devices, laboratory equipment, smart home automation, and PLC applications.
