It provides direct physical execution of modular 8-slot Field Bus Module (FBM) carrier housing and redundant power rail distribution. The assembly routes internal communication buses while regulating backplane voltage profiles to mounted I\/O modules.\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\u003eP0926JMA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eFoxboro\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\u003e0.2 kg (0.44 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e102.2 cm x 12.4 cm x 12.6 cm\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\u003ePassive (Backplane distribution: +5 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlot Capacity\u003c\/td\u003e\n\u003ctd\u003e8 Slots (Modular FBM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eDIN Rail Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temp\u003c\/td\u003e\n\u003ctd\u003e-40 to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity Rating\u003c\/td\u003e\n\u003ctd\u003e5-95% RH (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eDCS Backplane Communication and Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe Foxboro P0926JMA baseplate integrates high-density multi-layer printed circuit traces engineered to maintain deterministic bus communications across all 8 module positions. Designed for Foxboro I\/A Series architectures, the backplane traces deliver channel-to-channel isolation between power distribution buses and differential fieldbus communication loops. It conditions +5 VDC backplane power to preserve signal integrity and support transparent pass-through for 4-20 mA HART loop protocol field telemetry without inductive coupling.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the P0926JMA baseplate support hot-swapping of individual Field Bus Modules (FBMs)?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the backplane bus logic and connector pins allow live insertion and removal of individual FBM units without interrupting power or signal communication on adjacent operating slots.\u003c\/p\u003e\n\u003cp\u003eQ: How is backplane power redundancy managed across the 8 slots of the P0926JMA?\u003c\/p\u003e\n\u003cp\u003eA: The baseplate features integrated dual power distribution rails that route primary and secondary +5 VDC supply buses across all slots, ensuring continuous operation if one power feed degrades.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the P0926JMA baseplate horizontally onto standard DIN rails, ensuring all retention clamps latch tightly against the rail base.\u003c\/li\u003e\n\u003cli\u003eVerify that adjacent baseplates connect via dedicated HDLC interface cables before applying system backplane power.\u003c\/li\u003e\n\u003cli\u003eConnect the primary system ground strap to the dedicated grounding stud on the baseplate frame to ensure full EMI\/RFI shielding protection.\u003c\/li\u003e\n\u003cli\u003eAlign module keyways before inserting FBM units into any of the 8 slots to prevent pin bending on the +5 VDC backplane connector headers.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":53406167859509,"sku":"P0926JMA","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/P0926JMA.png?v=1787724401","url":"https:\/\/www.5gplc.com\/products\/p0926jma-foxboro-i-a-series-baseplate","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
