KS1-40DA is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. SSRs consist of a sensor which responses to an appropriate input (control signal), a solid-state electronic switching device that switches power to the load circuitry, and a coupling mechanism to enable the control signal to activate this switch without mechanical parts. It serves the same function as an electromechanical relay but has no moving parts.
Packaged solid-state relays use power semiconductor devices such as triacs to switch the current, 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).
