Schneider Electric XPSAK351144P Emergency Stop Module

Schneider Electric’s XPSAK351144P Emergency Stop Module is a Preventa XPS AK safety relay designed to monitor emergency-stop devices and related safety interfaces in industrial automation. This 120 V AC powered module provides three safety contacts and one auxiliary contact to support single- or dual-channel emergency-stop wiring, sensing-mat/edges monitoring, movable-guard supervision with two switches and automatic start, and proximity-sensor or safety-light-curtain monitoring as part of an integrated safety solution. It’s part of the Preventa safety automation family and offers configurable start, with performance up to PL e (category 4) per EN/ISO 13849-1 and SIL CL3 per EN/IEC 62061; safety reliability data include DC > 99%, MTTFd = 154.5 years, and PFHd = 7.39E-9 1/h. The unit weighs about 0.4 kg and is intended for panel-mounted installations where reliable emergency-stop signaling and safe-machine shutdown are required, commonly used with emergency-stop pushbuttons, movable guards, safety mats, and safety light curtains to coordinate interlocks and de-energize machinery in hazard situations.
