The unit converts continuous voltage and 4-20 mA current signals from transmitters into digital data across 16 software-configurable channels. Built-in EMI\/RFI shielding and channel-to-channel electrical isolation protect the assembly against noise interference 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\u003e51120673-101\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\u003e0.6 kg to 0.68 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e155 mm x 30 mm x 78 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\u003ePassive chassis backplane powered via Honeywell I\/O Link\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Capacity\u003c\/td\u003e\n\u003ctd\u003e16 universal channels (Software-configurable AI, AO, DI, DO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Inputs Supported\u003c\/td\u003e\n\u003ctd\u003e4-20 mA current loops, 0-10 V voltage signals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital Signal Support\u003c\/td\u003e\n\u003ctd\u003e24 VDC discrete inputs\/outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eHoneywell I\/O Link \/ Control Network chassis connection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiagnostics \u0026amp; Shielding\u003c\/td\u003e\n\u003ctd\u003eReal-time signal integrity monitoring, integrated EMI\/RFI shielding\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity Tolerance\u003c\/td\u003e\n\u003ctd\u003e5% to 95% RH non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Options\u003c\/td\u003e\n\u003ctd\u003ePlug-in module for standard Honeywell I\/O chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eCE, TUV, UL508, CSA, RoHS 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 51120673-101 module incorporates per-channel electrical isolation to separate field-side transmitter loops from internal backplane processing logic. Active suppression of common-mode voltage spikes preserves signal linearity across 4-20 mA HART loop circuits and 0-10 V voltage lines. Internal EMI\/RFI shielding mitigates high-frequency radiated noise inside the rack, preventing signal degradation during simultaneous analog input and digital switching operations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does hot-swapping operate when replacing the module inside an active Honeywell I\/O chassis?\u003c\/p\u003e\n\u003cp\u003eA: Technicians can insert or remove the module from the backplane chassis during live system operation. The host rack automatically maintains power isolation across adjacent slots, though field wiring terminal blocks must be disconnected to prevent voltage arcs during extraction.\u003c\/p\u003e\n\u003cp\u003eQ: How are individual channels configured for different analog or digital signal types?\u003c\/p\u003e\n\u003cp\u003eA: Software-configurable logic handles channel selection within the system software. Each of the 16 channels adapts to 4-20 mA, 0-10 V, or 24 VDC discrete behavior without requiring hardware jumper changes on the physical board.\u003c\/p\u003e\n\u003cp\u003eQ: What grounding steps preserve EMI\/RFI shielding integrity in electrically noisy enclosures?\u003c\/p\u003e\n\u003cp\u003eA: Grounding requires direct mechanical contact between the module chassis metal tabs and the grounded rack backplate. Shielded field cables must be grounded at the cabinet entry plate to prevent noise coupling across the differential signal inputs.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the 51120673-101 module vertically into an available slot within the Honeywell I\/O rack. Press the card edge connector straight into the backplane socket until the retaining clips snap into place. Connect the cabinet functional earth strap to the chassis ground rail to establish low-impedance grounding for internal EMI\/RFI shields.\u003c\/p\u003e\n\u003cp\u003eRoute field sensor cables through dedicated low-voltage wiring troughs, maintaining separation from high-power AC motor drives and switching lines. Terminate 4-20 mA loop lines and 0-10 V signal leads onto the corresponding field termination assembly, ensuring that external power supplies stay within rated operating bounds before enabling system channels.\u003c\/p\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51251111461176,"sku":"51120673-101","price":173.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/268..jpg?v=1788332239","url":"https:\/\/www.automodulexpert.com\/products\/51120673-101-honeywell-experion-dcs-analog-input-module","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
