Schneider Electric – XPSVNE3442LFP – Zero-Speed Detection Safety Relay

The Schneider Electric XPSVNE3442LFP is an obsolete zero-speed safety monitoring relay from the Preventa XPS series. At 115 V AC supply, it ensures safe machine shutdown by confirming rotor speed has dropped below a set threshold. It delivers 3 safety outputs (NO) and 3 diagnostics outputs (NC), certified to PL e and SIL 3 standards, and is DIN-rail mountable in industrial safety systems.
