Solid State Switch Circuit. I had a pva1352 left over from plasma cutter repair days. An ssr can be designed to switch a dc or an ac load and some types are capable of switching both ac and dc loads.
In this there is only semiconductor devices used no mechanical coil relay is used to switching the connected load. It serves the same function as an electromechanical relay but has no moving parts and therefore results in a longer operational lifetime. A transistor either bipolar or mos an scr or a triac.
A solid state relay ssr is an electronic switching device that switches on or off when an external voltage ac or dc is applied across its control terminals.
The atom switch has transitioned the circuit breaker from mechanical to digital in the most intelligent dynamic and fastest circuit breaker ever. Solid state relay optocoupler relay. Solid state switches software documentation resources back to all model families. A bidirectional solid state relay ssr can be considered an analog switch.
