Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 140CRA21110 is a Schneider Modicon Quantum DIO drop interface module, order code 140CRA21110, carrying 30 input and 32 output words over a single port. It operates on a 230 VAC supply and mounts on a Quantum backplane via a 7-pole terminal block, with a 3 A current output and 5.1 V voltage output. This module acts as a remote DIO drop interface for the Modicon Quantum automation platform, mapping 30 input and 32 output words between the backplane and field devices. The 3 A current output on the 5.1 V rail powers the interface logic and field-side electronics; the 0.2 A switching current handles the internal relay or solid-state switching for discrete signals. Diagnostics cover RAM address and checksum at both startup and runtime, giving the controller visibility into module health without additional wiring. The 50 W power draw is the module's total consumption from the backplane — factor this into the Quantum power supply budget when populating a rack. ## Applications DIO drop interfaces like the 140CRA21110 are used in distributed I/O architectures within Modicon Quantum systems, commonly found in process plants, water treatment facilities, and material handling lines where remote racks consolidate field signals back to a central controller. The single-port design suits applications with a single remote drop per segment. Within the Modicon Quantum family, the 140CRA21110 is a standard DIO drop interface — not a high-density or specialty module. It is specified by system integrators and plant engineers who need a straightforward remote I/O connection with UL 508, CSA, and DNV certifications, and who are already committed to the Quantum backplane architecture. The 140CRA21110 carries certifications including UL 508, CSA Class 1 Division 2, DNV, C-tick, and GOST, and is listed with California Proposition 65 compliance. No official lifecycle status (active / phase-out / obsolete) is recorded in the available evidence; for current production status and last-time-buy windows, request a lifecycle check on the RFQ.","metaTitle":"Schneider 140CRA21110 Modicon Quantum DIO Drop Interface, 30 I/32 O","metaDescription":"Schneider 140CRA21110 Modicon Quantum DIO drop interface module: 30 I/32 O words, 230 VAC, 3 A output, 5.1 V out, chassis mount, UL 508, CSA, DNV.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Category":"US1PC2118155","I/O words":"30 I/32 O","Standards":"UL 508","Module format":"Standard","Inrush current":"10 A 115 V 20 A 230 V","Number of port":"1 single","Output voltage":"5.1 V","lifecycle_stage":"eol_hot","Range of Product":"Modicon Quantum automation platform","Supply frequency":"47...63 Hz","Relative Humidity":"95 % without condensation","rated power in VA":"50 VA","Operating altitude":"<= 16404.2 ft (5000 m)","Typical backplanes":"3 positions 2 positions 6 positions 16 positions 10 positions 4 positions","Diagnostics startup":"RAM address RAM Checksum","Diagnostics run time":"RAM address RAM Checksum","Minimum load current":"0 A","Protective treatment":"TC","Nbr. of units in pkg.":"1","Supply voltage limits":"85...276 V","Associated fuse rating":"1.5 A","Maximum supply current":"0.2 A 115 V 0.4 A 230 V","Nominal Output Current":"3 A","Power dissipation in W":"11 W","Connections - Terminals":"Terminal block, 7 poles","Short-circuit protection":"With","Product or Component Type":"DIO drop interface","[Us] rated supply voltage":"115/230 V AC","Output overvoltage protection":"With","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":"$1,527.54 – $2,347.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/3e3521057b55e4b8effc397a8831218d.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/140CRA21110/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/140CRA21110","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/140CRA21110 when reusing this data.
