Solid State Relay (SSR) is a non-contact switch composed of microelectronic circuit, discrete electronic device and power electronic power device.The control end is separated from the load end by a photoelectric coupling or pulse signal.The input of the solid state relay uses tiny control signals to directly drive large current loads.
