A solid-state relay refers to an electronic switching device that can be turned on and off when an external voltage (DC or AC) is applied across control terminals. In many ways, it serves the same function as an electromechanical relay; however, the only difference between the two is that a solid-state relay carries a longer operational lifecycle as it has no moving parts. In addition, a solid-state relay consists of a sensor, an electronic switching device, and an efficient coupling mechanism.
