Schneider Electric XPSUEP34AP Preventa XPSU Cat. 4 48-240 V AC/DC Expansion 4 NO Safety Relay

The Schneider Electric XPSUEP34AP is a Preventa XPSU expansion module that adds 4 redundant NO safety outputs and 2 single NC outputs to an XPSUAF, XPSUAK, XPSUAT, XPSUDN or XPSUS base module via the safety extension bus. Powered at 48-240 V AC/DC, it reaches Category 4 / PLe per ISO 13849-1 and SIL 3 per IEC 61508. It cannot operate without a compatible XPSU base module.

Selection Notes

Choose the XPSUEP34AP when the base safety module it extends runs on the 48-240 V AC/DC universal supply — for example an XPSUAF33AP, XPSUAT33A3AP or XPSUDN33AP that has run out of NO/NC contacts for the contactors or drives it needs to switch. It adds the same 4 redundant NO + 2 single NC contact set as the 24 V XPSUEP14AP, matched to the higher voltage class so the expansion module's supply doesn't become the odd one out on the DIN rail. It carries no safety inputs of its own.
