The assembly converts 24 VDC field signals from switches and sensors into isolated digital logic states for process control processing. System-to-field safety is maintained through optical isolation and galvanic isolation rated at 1000 VAC RMS, while integrated Open Wire Detection (OWD) diagnostics monitor field circuit integrity across a -40 deg C to +70 deg C operating temperature envelope.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e8C-TDIL51 (PN: 51306969-175)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e160 mm x 40 mm x 130 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eField supply: 18 to 30 VDC (User-supplied); Channel input current \u0026lt;= 10 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Channels\u003c\/td\u003e\n\u003ctd\u003e32 discrete digital input channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Input Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC (Operating range: 18 to 32 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eON \/ OFF Sensing Limits\u003c\/td\u003e\n\u003ctd\u003eON: \u0026gt;= 13 VDC or \u0026gt;= 3 mA; OFF: \u0026lt;= 5 VDC or \u0026lt;= 1.2 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;= 10 k-ohm (Typical 4.2 k-ohm baseline dependent on configuration)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Rating\u003c\/td\u003e\n\u003ctd\u003eOptical isolation via IOM; 1000 VAC RMS galvanic isolation (system-to-field)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Propagation Delay\u003c\/td\u003e\n\u003ctd\u003eAbsolute delay ~5 ms +- 20%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnvironmental Limits\u003c\/td\u003e\n\u003ctd\u003eStorage: -55 deg C to +85 deg C; Relative Humidity: 0% to 95% non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShock and Vibration\u003c\/td\u003e\n\u003ctd\u003eShock: 15 g (11 ms half-sine); Vibration: 5 g RMS (10 to 500 Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiagnostics \u0026amp; Rating\u003c\/td\u003e\n\u003ctd\u003eOpen Wire Detection (OWD), channel status LEDs; IP20 cabinet enclosure rating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting \u0026amp; Certifications\u003c\/td\u003e\n\u003ctd\u003eVertical installation on Series 8 IOTA baseplate; CE, UL, RoHS, EMC compliant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e4-20 mA HART Loop Protocol and Channel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe 8C-TDIL51 module interfaces with Series 8 I\/O Termination Assemblies (IOTA) to maintain signal purity in high-density process environments. Integrated optical decoupling protects central C300 controllers against ground potential shifts and field-side electrical surges. Differential input threshold detection works alongside system-level filtering to evaluate discrete states without introducing crosstalk into adjacent analog 4-20 mA HART loops or Fieldbus communication segments residing on neighboring Series 8 baseplates.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the module handle hot-swapping under live field power conditions?\u003c\/p\u003e\n\u003cp\u003eA: The 8C-TDIL51 module supports online insertion and removal (hot-swapping) on the Series 8 IOTA baseplate. Main system backplane communications remain active during module replacement, provided external 24 VDC field power isolation limits are observed to prevent electrical arcs across the connector pins.\u003c\/p\u003e\n\u003cp\u003eQ: What mechanisms are used to detect field wiring faults on the digital input channels?\u003c\/p\u003e\n\u003cp\u003eA: The module executes real-time Open Wire Detection (OWD) diagnostics alongside continuous channel status monitoring. When an open-circuit condition is detected on a monitored field contact loop, the IOM diagnostic register flags a fault bit to the C300 controller without interrupting the operation of unaffected channels.\u003c\/p\u003e\n\u003cp\u003eQ: What installation requirements apply to the coated version of the module in humid or corrosive spaces?\u003c\/p\u003e\n\u003cp\u003eA: Coated variants of the 8C-TDIL51 are chemically treated to withstand corrosive gases and relative humidity levels up to 95% non-condensing. However, cabinet installations must still maintain IP20 enclosure protection standards and adhere to vertical mounting profiles on the Series 8 baseplate to guarantee thermal convection flow.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the 8C-TDIL51 module vertically onto its dedicated Series 8 IOTA baseplate. Align the rear multi-pin connector with the baseplate socket and press firmly until the mechanical side latches lock into position. Secure the baseplate assembly to the cabinet enclosure ground using a low-impedance copper earth strap to establish proper functional grounding and EMC protection.\u003c\/p\u003e\n\u003cp\u003eRoute field wiring through low-voltage signal conduits separate from high-power AC distribution lines. When landing external 24 VDC supply cables, verify that polarity matches the terminal block assignments and that the supply remains within the specified 18 to 30 VDC operating envelope. Shielded field cables should be grounded at a single point on the cabinet entry gland plate to eliminate circulating ground loops across field switches.\u003c\/p\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51251097796920,"sku":"8C-TDIL51 51306969-175","price":173.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/8C-TDIL51_51306969-175.jpg?v=1760691631","url":"https:\/\/www.automodulexpert.com\/products\/8c-tdil51-51306969-175-honeywell-experion-c300-input-module","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
