packaged solid-state relays use power semiconductor devices such as thyristors and transistors, to switch currents up to around a hundred amperes. solid-state relays have fast switching speeds compared with electromechanical relays, and have no physical contacts to wear out. application of solid-state relays must consider their lower ability to withstand momentary overload, compared with electromechanical contacts, and their higher "on" state resistance. unlike an electromechanical relay, a solid-state relay provides only limited switching arrangements (spst switching).









































section::::coupling.









































the control signal must be coupled to the controlled circuit in a way which provides galvanic isolation between the two circuits.
