The module interfaces field instrument wiring directly to Fieldbus Modules (FBMs), routing up to 24 channels of analog (4-20 mA, RTD, thermocouple) and discrete signals. By employing removable terminal blocks and internal galvanic isolation, the unit protects central logic cards against field-side electrical surges and ground loops while providing physical signal pass-through.\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\u003eP0973KJ\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\u003eStandard Field Assembly Weight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard DIN-Rail\/Panel Mount Footprint\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePassive (Driven by FBM Baseplate)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Capacity\u003c\/td\u003e\n\u003ctd\u003eUp to 24 Channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Types\u003c\/td\u003e\n\u003ctd\u003e4-20 mA, RTD, Thermocouple, Discrete Input\/Output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField Connection\u003c\/td\u003e\n\u003ctd\u003eRemovable Terminal Blocks (Spring Clamp \/ Screw Type)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWiring Capacity\u003c\/td\u003e\n\u003ctd\u003e18 to 22 AWG Copper Conductors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eGalvanic Isolation (Field Wiring to System Logic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eDIN Rail or Panel Baseplate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure Protection\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProcess Control \u0026amp; Field Interface Dynamics\u003c\/h3\u003e\n\u003cp\u003eEngineered for fieldbus-level process control architectures, the assembly integrates cold junction compensation pathways and channel-to-channel isolation barriers essential for 4-20 mA HART loop protocol communications. The passive backplane routing prevents signal attenuation across high-density field wiring networks. Integrated galvanic isolation suppresses common-mode interference, protecting downstream analog and discrete FBM processing modules from high-voltage field spikes during continuous scanning cycles.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the field terminal blocks be removed without disconnecting the individual signal wires?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The assembly uses removable compression terminal blocks that allow maintenance personnel to swap FBM hardware or field wiring assemblies without disturbing individual wire terminations.\u003c\/p\u003e\n\u003cp\u003eQ: What wire gauge range does the terminal block hardware accept?\u003c\/p\u003e\n\u003cp\u003eA: The terminal blocks accept 18 AWG to 22 AWG solid or stranded copper conductors for standard field instrument wiring.\u003c\/p\u003e\n\u003cp\u003eQ: Does the assembly require external DC power inputs to operate?\u003c\/p\u003e\n\u003cp\u003eA: No. The termination assembly operates as a passive interface structure, drawing logic power and loop power directly from the connected FBM baseplate and field loop circuits.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the assembly vertically onto a standard DIN rail or panel baseplate within an IP54 or better protective enclosure. Ensure mechanical mounting latches seat firmly to prevent movement under industrial vibration conditions. Strip field conductor insulation to the manufacturer-specified length (typically 7 mm) before inserting cables into the spring clamp or screw terminals.\u003c\/p\u003e\n\u003cp\u003eEstablish a single-point shield ground connection for shielded twisted-pair cables at the designated cabinet ground bar, isolating the shield at the field instrument end to prevent ground loops. Verify that total wire runs observe standard 4-20 mA loop impedance limits. Maintain physical separation between low-voltage signal wiring and high-voltage AC power lines within cabinet wire ducts to prevent inductive noise coupling.\u003c\/p\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":43931613167706,"sku":"P0973KJ","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/316_f7ad981f-40d8-45e0-9aa2-9f0670b7887d.jpg?v=1787904576","url":"https:\/\/www.spareoil.com\/products\/p0973kj-foxboro-i-a-series-termination-assembly-fieldbus-module-interface","provider":"SpareOil Automation","version":"1.0","type":"link"}
