SSR - Solid State Relay

A Solid State Relay (SSR) is an electronic switching device used in automation systems. SSR's use a semiconductor switching element to turn on and off a circuit, and can control AC or DC loads up to several hundred amps. SSR's offer a number of advantages over traditional mechanical relays, such as higher switching speed, lower power consumption, and greater reliability. They can be used to switch both AC and DC loads, and are an ideal choice for applications that require an isolated, low-voltage control signal.
