It carries one Modbus Plus port and two Modbus RS232 serial ports, runs on ProWORX 32 or Concept software, and is certified to UL 508, CSA C22.2 No 142, cUL, FM Class 1 Division 2, and CE. The 140CPU43412AC is a mature Modicon Quantum processor; it is not listed as obsolete in the current evidence, but as a mature offer it is sourced through distribution and surplus channels — an RFQ confirms current availability and lead time for the exact build code.","metaTitle":"Schneider 140CPU43412AC Modicon Quantum processor, 896 kB RAM","metaDescription":"Schneider 140CPU43412AC Modicon Quantum processor: 80486 CPU, 896 kB RAM, 1 Modbus Plus + 2 Modbus RS232 ports, UL/CSA/cUL/FM/CE certified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Marking":"CE","Category":"18150-QUANTUM CONTROLLERS,HSBY,COMM.","I/O words":"30 I/32 O distributed 64 I/64 O max local 64 I/64 O remote","Standards":"UL 508 CSA C22.2 No 142","Clock drift":"+/-8 s/day 32...140 °F (0...60 °C)","Battery Life":"10 year(s)","Battery type":"Lithium 7 µA 210 µA","Drops/network":"63 distributed","Module format":"Standard","Software name":"ProWORX 32 Concept","Number of port":"1 Modbus Plus 2 Modbus RS232","Processor name":"80486","Watchdog timer":"250 ms","Clock frequency":"66 MHz","Number of drops":"31 remote","Switch Function":"Key switch","lifecycle_stage":"eol_hot","Battery Capacity":"1.2 Ah","Range of Product":"Modicon Quantum automation platform","I/O words/network":"500 I/500 O distributed","Number of network":"2 remote 3 distributed","Relative Humidity":"95 % without condensation","Memory description":"Internal RAM 896 kB","Operating altitude":"<= 16404.2 ft (5000 m)","Protective treatment":"Conformal coating Humiseal 1A33","Nbr. of units in pkg.":"1","Bus current requirement":"1250 mA","Mathematical coprocessor":"With","Product or Component Type":"Processor","Exact time for 1 Kinstruction":"0.1...0.5 ms LL984","Ambient Air Temperature for Storage":"-40...185 °F (-40...85 °C)","Resistance to electromagnetic fields":"9.1 V/m (10 V/m) 80...2000 MHz IEC 801-3","Ambient Air Temperature for Operation":"32...140 °F (0...60 °C)","Resistance to electrostatic discharge":"4 kV contact IEC 801-2 8 kV on air IEC 801-2","Communication module processor capacity":"6 NOM, NOE, CR, NMS"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$27,914.54","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/6289e896d56e3192a3dbde84cafe238a.pdf","sourceUrl":"https://www.se.com/us/en/product/140CPU43412AC/processor-80486-modicon-quantum-1-modbus-plus-2-modbus-rs232/","alternativesUrl":"https://aoctrl.com/api/mcp/products/140CPU43412AC/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/140CPU43412AC","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/140CPU43412AC when reusing this data.
