The module converts physical field transmitter currents into digital process values across internal backplane buses. It processes incoming control signals with active electrical isolation to maintain loop integrity and prevent field-side voltage transients from corrupting central processor operations.\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\u003e51196694-904\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\u003e1.1 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e51 mm x 267 mm x 178 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e24 VDC system bus powered\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eAdvanced Input Device (DCS Module)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eHoneywell TDC 3000 \/ Experion PKS platforms\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 51196694-904 input assembly incorporates high-density signal conditioning circuits designed for direct 4-20 mA HART loop protocol routing. Galvanic channel-to-channel isolation prevents common-mode noise and ground potential differences between field instrument loops from introducing offset errors into process measurement channels. The internal filter network continuously decouples power rail noise, sustaining dynamic HART digital frequency-shift keying (FSK) communication without degrading primary analog current measurements.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 51196694-904 module support hot-swapping inside an active card chassis?\u003c\/p\u003e\n\u003cp\u003eA: Hot-swapping is supported by the backplane bus interface, provided the module extraction guide levers are fully disengaged to prevent transient bus lockup during pin break.\u003c\/p\u003e\n\u003cp\u003eQ: How does the module maintain channel-to-channel isolation during field wire fault conditions?\u003c\/p\u003e\n\u003cp\u003eA: Individual input circuits are galvanically decoupled using high-speed optical isolators, preventing high voltage surges on one field loop from destroying adjacent channel electronics.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eAlign the card edge connector with the rack slot guides and slide the assembly firmly into the backplane receiver until the locking latches engage.\u003c\/li\u003e\n\u003cli\u003eVerify that field wiring terminal connections maintain solid mechanical contact with low contact resistance.\u003c\/li\u003e\n\u003cli\u003eKeep field signal wiring separate from high-voltage AC lines and inductive drive cables inside cabinet wireways.\u003c\/li\u003e\n\u003cli\u003eEnsure the cabinet functional earth (FE) ground terminal is bonded to the main station ground grid using low-impedance grounding conductors.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53625346195765,"sku":"51196694-904","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/51196694-904_Cocoai.png?v=1790047831","url":"https:\/\/www.5gplc.com\/products\/honeywell-51196694-904-dcs-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
