It achieves PL e / category 4 per EN/ISO 13849-1 and SILCL 3 per EN/IEC 62061, with an MTTFd of 210.4 years and PFHd of 3.56E-9 1/h, backed by CSA, UL, and TÜV certifications. Schneider has discontinued the XPSAC3721P; remaining units are available through surplus and broker channels. An RFQ confirms current availability and lead time for line-down or last-time-buy needs.","metaTitle":"Schneider XPSAC3721P Preventa safety module, 230 V AC, discontinued","metaDescription":"Schneider XPSAC3721P Preventa safety module: emergency stop monitoring, 230 V AC supply, 3 NO relay outputs, PL e / SILCL 3, IP20, discontinued since 2021.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Standards":"EN/ISO 13850 EN 60204-1 EN/IEC 60947-5-1 EN 1088/ISO 14119","Output type":"Relay instantaneous opening, 3 NO circuit(s), volt-free","Safety level":"Can reach PL e/category 4 conforming to EN/ISO 13849-1 Can reach SILCL 3 conforming to EN/IEC 62061","Type of start":"Unmonitored","lifecycle_stage":"unknown","Local signalling":"2 LEDs","Mounting support":"35 mm symmetrical DIN rail","Range of product":"Preventa Safety automation","Supply frequency":"50/60 Hz","Breaking capacity":"1.5 A at 24 V (DC-13) time constant: 50 ms for relay output","Function of module":"Emergency stop Switch monitoring","Safety module name":"XPSAC","Current consumption":"25 mA at 230 V AC on power supply","Associated fuse rating":"4 A gG or gL for relay output conforming to EN/IEC 60947-5-1, DIN VDE 0660 part 200 6 A fast blow for relay output conforming to EN/IEC 60947-5-1, DIN VDE 0660 part 200","Minimum output current":"10 mA for relay output","Minimum output voltage":"16 V for relay output","Output thermal current":"6 A per relay for relay output","Connections - terminals":"Captive screw clamp terminals, removable terminal block, 1 x 0.2...1 x 2.5 mm² flexible with cable end, with double bezel Captive screw clamp terminals, removable terminal block, 1 x 0.2...1 x 2.5 mm² solid with cable end, with double bezel Captive screw clamp terminals, removable terminal block, 1 x 0.25...1 x 2.5 mm² flexible with cable end, with double bezel Captive screw clamp terminals, removable terminal block, 2 x 0.2...2 x 1 mm² solid with cable end, with double bezel Captive screw clamp terminals, removable terminal block, 2 x 0.2...2 x 1.5 mm² flexible with cable end, with double bezel Captive screw clamp terminals, removable terminal block, 2 x 0.25...2 x 1 mm² flexible with cable end, with double bezel Captive screw clamp terminals, removable terminal block, 2 x 0.5...2 x 1.5 mm² flexible with cable end, with double bezel","IP degree of protection":"IP20 (terminals) conforming to EN/IEC 60529 IP40 (enclosure) conforming to EN/IEC 60529","Safety reliability data":"MTTFd = 210.4 years conforming to EN/ISO 13849-1 DC > 99 % conforming to EN/ISO 13849-1 PFHd = 3.56E-9 1/h conforming to EN/IEC 62061","Product or component type":"Preventa safety module","Safety module application":"For emergency stop and switch monitoring","[Us] rated supply voltage":"230 V AC - 15...10 %","[Uc] control circuit voltage":"230 V","Number of additional circuits":"1 solid state output","[Ui] rated insulation voltage":"300 V (pollution degree 2) conforming to IEC 60947-5-1 300 V (pollution degree 2) conforming to DIN VDE 0110 part 1","Maximum power consumption in VA":"6 VA AC","Ambient air temperature for storage":"-25...85 °C","Maximum response time on input open":"100 ms","Ambient air temperature for operation":"-10...55 °C","[Uimp] rated impulse withstand voltage":"4 kV overvoltage category III conforming to IEC 60947-5-1 4 kV overvoltage category III conforming to DIN VDE 0110 part 1","[Ith] conventional free air thermal current":"10.5 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$109.22","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/ed6c382663fd2f3886bb0c8248ecae38.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/XPSAC3721P/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/XPSAC3721P","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/XPSAC3721P when reusing this data.
