This 16-channel digital hardware board detects standard 24V DC discrete signals from field-level devices, including mechanical limit switches, operator push buttons, and safety proximity sensors. The module captures these raw electrical states, filters out transient circuit noise, and converts the binary inputs into structured digital data arrays for the central Honeywell C300 controller. To secure processing operations against the software errors and electrical flaws common in salvaged or surplus equipment, this shipment provides exclusively 100% brand new, original factory-sealed Series C components.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification Details\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eManufacturer\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eHoneywell Automation\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eModel Designation\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eTC-IDJ161\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eFunctional Classification\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eDiscrete \/ Digital DC Input Board\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eTotal Monitored Channels\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e16 Independent Channels\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eNominal Field Input Voltage\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e24V DC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOperational Input Voltage Range\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e18V DC to 30V DC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eGuaranteed ON State Voltage\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eGreater than 15V DC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eGuaranteed OFF State Voltage\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eLess than 5V DC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eCurrent Consumption Per Channel\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eTypically 7 mA per channel at 24V DC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eSignal Conditioning\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eFixed hardware filter for industrial noise suppression\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMaster DCS Compatibility\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eHoneywell Experion PKS (EPKS) Architecture\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePrimary Processor Link\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eC300 Controller Systems\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eDiagnostic Array\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eOn-board LEDs for module power status and channel tracking\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePhysical Dimensions\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2.2 x 12.4 x 12.6 cm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePhysical Hardware Weight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0.3 kg\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eSystem Installation Method\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eInsertion interface onto a Series C Input Output Termination Assembly (IOTA)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eEngineering Advantages\u003c\/h3\u003e\n\u003cp\u003eThe TC-IDJ161 optimizes spatial efficiency inside control cabinets through an ultra-slim, vertical form factor that boosts point density within tight footprints. Technicians insert the module directly onto a matching Series C Input Output Termination Assembly (IOTA), separating the field wiring connections from the sensitive active processing components. This mechanical architecture allows facilities to execute hot-swapping routines on the board without loosening individual field cables, which keeps adjacent I\/O channels online and eliminates processing interruptions.\u003c\/p\u003e\n\u003cp\u003eThe internal electrical interface uses built-in hardware filters to eliminate electrical background noise and contact bounce originating from remote field installations. By filtering out high-frequency interference before the data reaches the C300 controller, the board prevents false triggering and provides clean binary data to the control strategy execution engine. Additionally, the faceplate includes individual channel status LEDs that provide physical verification of active inputs, helping field technicians diagnose field-level component issues without using external software diagnostic meters.\u003c\/p\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat electrical thresholds determine whether a field contact registers as an ON or OFF signal?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe TC-IDJ161 features strict voltage discrimination zones to prevent unstable signal tracking. The internal monitoring circuits register a definite ON state when the incoming terminal potential rises above 15V DC. Conversely, the signal registers as a definite OFF state when the terminal potential falls below 5V DC, isolating the controller from stray trickle currents or leakage voltages.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this digital input board require a separate external wire termination block?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The TC-IDJ161 plugs directly into a dedicated Series C Input Output Termination Assembly (IOTA). All field instrumentation cables terminate permanently onto the heavy-duty screw terminals of the IOTA base plate, allowing you to install, extract, or swap the active module body without rewiring your field instruments.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCan you mount this specific hardware module into an older TDC 3000 chassis layout?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The TC-IDJ161 utilizes the mechanical housing format, connection keys, and electrical protocols unique to the Honeywell Experion PKS Series C platform. It interfaces specifically with C300 controller infrastructure via standard Series C IOTA backplanes, preventing insertion into older legacy TDC chassis profiles.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":42870825386074,"sku":"TC-IDJ161","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/161..jpg?v=1772676070","url":"https:\/\/www.spareoil.com\/products\/tc-idj161-honeywell-c300-controller-discrete-input-card","provider":"SpareOil Automation","version":"1.0","type":"link"}
