SSR-25DA is 25A, solid state relay. A DC to AC Solid State Relay (SSR) is an electronic switching device that allows a direct current (DC) input signal to control the switching of an alternating current (AC) output load. It uses solid state components like thyristors, triacs, or transistors to perform the switching function, without the need for mechanical contacts like in traditional electromechanical relays.

SSRs are commonly used in various applications where precise and rapid switching of AC loads is required, such as in industrial control systems, heating elements, motor control, and more. They offer advantages like faster switching times, longer lifespan due to no mechanical wear, and reduced electromagnetic interference compared to traditional relays.
