Solid State Relay

A Solid State Relay (or SSR) can refer to any device which utilizes a semiconductor switching element to electronically switch a load on or off in response to an externally controlled input. These relays offer several advantages over conventional mechanical relays, including faster switching speed, smaller size, and greater reliability. Common applications for SSRs include lighting control, motor drive systems, industrial automation, and process control.
