Autonics Corporation SR1-1415-N Solid State Relay

The SR1-1415-N is Autonics' detachable-heatsink single-phase solid-state relay (1 Form A) rated for 15 A continuous operation, designed to switch AC loads from 48 to 480 VAC and controlled by a 4–30 VDC input signal. Operating with zero-cross turn-on to minimize inrush and electrical noise, it provides input-output isolation with a dielectric strength of 2500 VAC (50/60 Hz, 1 minute) and mounts on a panel using the included detachable heatsink. The device is specified for -30 to 80 C ambient operation (storage -30 to 100 C) and 45 to 85% relative humidity, with the detachable heatsink allowing easier maintenance or replacement of cooling hardware in compact installations. With a weight around 111 g and 15 A load current rating, the SR1-1415-N is suitable for controlling resistive and inductive AC loads such as heaters, motors, and transformers in compact control panels where safety isolation and robust performance at 48–480 VAC are required.
