Solid State Relay 40VA  is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. it consists of a sensor which response to an appropriate input (control signal). Solid State Relay 40A which switches power to the load circuitry, and a coupling mechanism to enable the control signal to activate this switch without mechanical parts.
