Schneider Electric XPSUAF33AP Preventa XPSU Cat. 4 Universal 48-240 V AC/DC 3 NO Safety Relay

The Schneider Electric XPSUAF33AP is a Preventa XPSU universal safety relay module that monitors emergency stop, guard switch, magnetic switch, proximity sensor, RFID switch or light-curtain inputs. Powered at 48-240 V AC/DC, it provides 2 safety inputs and 3 NO safety outputs, reaching Category 4 / PLe per ISO 13849-1 and SIL 3 per IEC 61508.

Selection Notes

Choose the XPSUAF33AP when the machine's control circuit runs on a voltage anywhere from 48 V to 240 V AC or DC rather than a fixed 24 V rail — the same 2-input / 3-NO-output function set as the XPSUAF13AP is available, with the supply range absorbing site-to-site voltage differences on multi-voltage equipment lines. Its slightly higher 3.0 W / 6.5 VA consumption reflects the wider input range, not a difference in switching capacity, since both variants share the 5 A / 8 A current ratings. Pick the 6-input XPSUDN33AP instead if more than two safety circuits need monitoring at this voltage class.
