Autonics SR1-4440-N Single-Phase Solid State Relay, Panel Mount SSR

The Autonics SR1-4440-N is a single-phase, panel-mount solid state relay designed for reliable AC load switching in industrial control applications. It features a 40A load current rating, 48–480VAC load voltage range, and 90–240VAC input control voltage. This SSR uses zero-cross switching for reduced electrical noise and smoother operation when controlling resistive or compatible AC loads.
