Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 140NOM21100 is a Schneider Modicon Quantum DIO head-end adaptor, order code 140NOM21100, handling 30 input and 32 output words with a power draw of 4.0 W. It mounts on a chassis and carries one Modbus Plus RS485 twisted-pair port and one Modbus RS232 port, both single copper. The module is UL 508 listed and is now discontinued by the manufacturer. ## Applications This adaptor is used in Modicon Quantum-based distributed control systems where I/O racks are located remotely from the main controller — common in process plants, water treatment facilities, and material handling lines. It bridges the backplane to field I/O over Modbus Plus, reducing wiring runs and centralising diagnostics.","metaTitle":"Schneider 140NOM21100 Modicon Quantum DIO Head-End Adapter","metaDescription":"Schneider Modicon Quantum 140NOM21100 DIO head-end adaptor, 30 I/32 O words, 1 Modbus Plus RS485 + 1 Modbus RS232, 4.0 W, chassis mount, UL 508.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Checks":"Processor Checksum RAM address RAM","Category":"US1PC2118150","I/O words":"30 I/32 O","Standards":"UL 508","Module format":"Standard","Number of port":"1 Modbus Plus RS485 twisted pair single copper 1 Modbus RS232 twisted pair single copper","lifecycle_stage":"eol_hot","Range of Product":"Modicon Quantum automation platform","Relative Humidity":"95 % without condensation","Transmission Rate":"1 Mbit/s","Operating altitude":"<= 16404.2 ft (5000 m)","Nbr. of units in pkg.":"1","Power dissipation in W":"4 W","Bus current requirement":"780 mA","Product or Component Type":"DIO head-end adaptor","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"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3,659.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/0cc5613a797f6a5016cef375bcd82a2b.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/140NOM21100/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/140NOM21100","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/140NOM21100 when reusing this data.
