Q. What is the use of static relay?

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.
