Q. What is the use of static relay?

Answer

To control multiple circuits with a single signal or to allow a circuit to be controlled by a low-power signal, a static relay is utilized. Solid-state relays, which employ semiconductor features for control rather than moving elements, are one example of a departure from the conventional electromagnet-powered relay. While repeated pulses of the same type have no impact, applying a pulse to a different set of control terminals or applying a pulse with the opposite polarity resets the switch.
