Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 140DDI35300C is a Schneider Modicon Quantum automation platform low-voltage DC discrete input module, order code 140DDI35300C, providing 32 input points across 4 channels at 24 V DC with positive (sink) logic. It draws 1.7 W from the backplane, mounts on a Quantum chassis, and carries CE marking plus UL 508 and CSA C22.2 No 142 certifications. Input protection is resistor-limited; the absolute maximum input rating is 30 V continuous, with a 56 V decaying pulse tolerance for 1.3 ms — enough to survive brief transients on a 24 V DC control bus. Isolation between groups is 500 Vrms for 1 minute, and isolation between group and bus is 1780 Vrms for 1 minute, providing robust noise separation in mixed-voltage cabinets. The module carries conformal coating (Humiseal 1A33) for protection against moisture and contaminants, and operates over a storage temperature range of -40 to 185 °F (-40 to 85 °C). ## Applications This 32-point DC input module is used in Modicon Quantum racks for discrete sensing in machine control, material handling, packaging, and process skids — reading limit switches, proximity sensors, pushbuttons, and photo-eyes into the controller's logic map. Within the Modicon Quantum automation platform, the 140DDI35300C is a standard-density 32-point DC input module specified for applications that need positive-logic (sink) input wiring. It sits alongside the 140DDI35310 (negative/source logic) and the 140DAI35300 (AC input) as a logic-family choice for the same 4-channel, 32-point frame. The 140DDI35300C carries CE marking and is certified to UL 508 and CSA C22.2 No 142, with additional marine approvals (RMRS, ABS, GOST, BV, DNV, RINA). It also complies with California Proposition 65. The module is conformally coated and carries an 18-month warranty.","metaTitle":"Schneider 140DDI35300C Modicon Quantum 32-point DC Input Module","metaDescription":"Schneider Modicon Quantum 140DDI35300C discrete input module: 32 points, 24 V DC, positive logic (sink), 4 channels, 1.7 W, CE, UL 508.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Marking":"CE","Category":"US1PC2118155","Standards":"CSA C22.2 No 142 UL 508","Logic input":"Positive (sink)","Module format":"Standard","Response Time":"<= 1 ms from state 1 to state 0","Input impedance":"2500 Ohm","Protection Type":"Input protection by resistor limited","lifecycle_stage":"eol_hot","Local signalling":"1 LED (green) for bus communication is present (Active) 1 LED (red) for external fault detected (F) 32 LEDs (green) for input status","Range of Product":"Modicon Quantum automation platform","Group of channels":"4","Power dissipation":"1.7 W + (0.36 x number of points on)","Relative Humidity":"95 % without condensation","Operating altitude":"<= 16404.2 ft (5000 m)","Input voltage limits":"19.2...30 V","Protective treatment":"Conformal coating Humiseal 1A33","Discrete input number":"32","Nbr. of units in pkg.":"1","Absolute maximum input":"30 V continuous 56 V during 1.3 ms decaying pulse","Addressing requirement":"2 input words","Discrete input voltage":"24 V DC","Bus current requirement":"330 mA","Isolation between group":"500 Vrms for 1 minute","Maximum leakage current":"200 mA at Us = 5.5 V and Uin = 4 V","Product or Component Type":"Low voltage dc discrete input modules","Current state 0 guaranteed":"<= 0.5 mA","Current state 1 guaranteed":">= 2 mA at Us = 5.5 V and Uin = 0 V","Voltage state 0 guaranteed":"-3...5 V DC","Voltage state 1 guaranteed":"15...30 V DC","Isolation between group and bus":"1780 Vrms for 1 minute","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":"$1,950.00 – $2,849.38","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/480b4ad8f726947f37af2efacdd8e9dd.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/140DDI35300C/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/140DDI35300C","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/140DDI35300C when reusing this data.
