SSR SOLID STATE RELAY 2 CHANNEL
SSR SOLID STATE RELAY 2 CHANNEL
SOLID STAE RELAY is an IC that acts like a mechanical relay. SSR consist of a sensor which responds to an appropriate input (control signal),
a solid-state electronic switching device which switches power to the load circuitry, and a coupling mechanism to enable
the control signal to activate this switch without any mechanical parts.
SSR works as follow picture. When there is no signal in the input, the output terminal disconnected;
when the input signal be active, the 2 outputs of the SSR connected so the whole load circuit connected:
