Solid state relay (SSR) is a non-contact switch which drives a high-current load with a small control signal. The solid state relay consists of three parts, namely, the input circuit, the isolation (coupling) and the output circuit.Compared with the electromagnetic relays, solid state relays are characterized with high reliability, no contact, no spark, no noise, strong anti-interference ability, long lifetime, and fast switching speed. Now SSR are widely used in automation equipment, CNC machines, remote control system, instrumentation, medical equipment and so on.
