Schneider Electric XPSAK311144 E-Stop Safety Relay Module

The Schneider Electric Preventa XPSAK311144 Emergency Stop Safety Relay Module is a three‑channel safety relay block that energizes from 24 V AC or 24 V DC and safely interrupts machinery when an E‑stop is pressed. Designed to monitor emergency‑stop devices, sensing mats/edges, and safety light curtains, it provides three normally open, volt‑free safety contacts plus a relay signaling output. In safety‑system terms, the XPSAK311144 supports Cat 4 / PL e configurations when deployed in properly engineered circuits. The unit's 24 V operation and a breaking capacity of 1.5 A at 24 V (DC‑13), with an approximate 50 ms relay time constant for fault clearance, make it suitable for rapid stop signaling. Compact and modular, it is intended for mounting in standard control cabinets and is part of the Preventa XPSAK family for emergency‑stop safety circuits in applications such as packaging lines, machine tools, and conveyors.
