Autonics SR1-4225-N Single-Phase Solid State Relay, Panel Mount SSR

The Autonics SR1-4225-N is a single-phase solid state relay designed for reliable AC load switching in industrial control systems. It features a 90–240 VAC control input, 24–240 VAC load voltage range, and 25 A rated load current. This panel/chassis mount SSR uses a SPST-NO / 1 Form A output configuration with zero-cross switching, helping reduce electrical noise during load operation.
