The assembly accepts a nominal input voltage of 24 VDC to route power across internal backplane rails at current capacities up to 20 A. Weighing 2.00 kg and enclosed within a 30 cm x 20 cm x 20 cm structural frame manufactured by Eldre Corp, the board enforces continuous 24 VDC potential distribution across connected controller cards and system sub-assemblies.\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\u003e51403896-100\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\u003e2.00 kg (4.4 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e30 cm x 20 cm x 20 cm (11.8 in x 7.9 in x 7.9 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePassive distribution (up to 20 A load capacity)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Current Rating\u003c\/td\u003e\n\u003ctd\u003eUp to 20 A (configuration dependent)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Sub-Assembly\u003c\/td\u003e\n\u003ctd\u003eEldre Corp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eHoneywell TDC 3000 \/ Process Manager Cabinets\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 \u0026amp; Channel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe 51403896-100 power distribution assembly features low-impedance copper bus structures designed to minimize ground loop offsets across internal 24 VDC distribution branches. When supplying power to field I\/O modules processing 4-20 mA HART loop protocol signals, the laminated planar construction suppresses high-frequency power supply ripple and noise spikes. This bus geometry preserves channel-to-channel isolation ratings on downstream analog cards, ensuring stable signal transmission without crosstalk or common-mode potential shifts.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 51403896-100 power bus component be replaced while the 24 VDC main supply is energized?\u003c\/p\u003e\n\u003cp\u003eA: No, main cabinet DC power must be completely isolated prior to removing or installing the bus assembly to prevent high-current arcing across bus bar mounting studs.\u003c\/p\u003e\n\u003cp\u003eQ: What is the primary purpose of the laminated bus bar design manufactured by Eldre Corp for this model?\u003c\/p\u003e\n\u003cp\u003eA: The laminated bus bar structure lowers internal inductance and resistance compared to discrete wire harnesses, ensuring uniform 24 VDC voltage levels across all connected module slots under full 20 A load conditions.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDe-energize the main 24 VDC power supply feed to the control cabinet and verify zero potential across all bus terminals using a calibrated multimeter.\u003c\/li\u003e\n\u003cli\u003eAlign the 51403896-100 assembly with the cabinet chassis mounting points, ensuring correct physical orientation relative to the horizontal backplane slot alignment.\u003c\/li\u003e\n\u003cli\u003eFasten all mechanical retention hardware and torque terminal connection bolts to factory specification to establish low-resistance electrical contacts.\u003c\/li\u003e\n\u003cli\u003eVerify frame ground continuity between the metallic distribution chassis and the central cabinet earth bar prior to reapplying 24 VDC power.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53626059882805,"sku":"51403896-100","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/51403896-100_Cocoai.png?v=1790057629","url":"https:\/\/www.5gplc.com\/products\/51403896-100-honeywell-tdc-3000-power-distribution-bus-component","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
