The Field Termination Assembly (FTA) provides direct physical\/electrical execution to bridge field instrumentation loops with the system's analog input modules. It organizes and interfaces 16 continuous process loops natively at the hardware tier while maintaining high-impedance voltage tracking paths.\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\u003eMC-TAIH03\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e51309136-175\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\u003e0.3 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e150 mm x 80 mm x 15 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-40 to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e24 VDC nominal loop potential\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e16 analog input channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Range\u003c\/td\u003e\n\u003ctd\u003e4-20 mA current loops \/ 0-10 VDC tracking paths\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Window\u003c\/td\u003e\n\u003ctd\u003e+\/- 10 VDC maximum limits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/- 0.1% of full-scale tracking span\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Resolution\u003c\/td\u003e\n\u003ctd\u003e16 bits signal differentiation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eHoneywell Experion LX Distributed Control System \/ UCN Arrays\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eAnalog Input Terminations\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProcess Control \u0026amp; DCS Instrumentation Telemetry\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-20 mA HART Loop Protocol and Secondary Telemetry Bridging\u003c\/strong\u003e The MC-TAIH03 establishes dedicated conditioning paths for standard 4-20 mA process loops.

The high input impedance infrastructure minimizes loading effects, preventing common-mode voltage spikes or field ground loop currents on one circuit from corrupting adjacent channels or affecting the low-voltage processing backplane registers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What programmatic or electrical behaviors manifest if a field loop experiences a short circuit directly on an MC-TAIH03 channel?\u003c\/p\u003e\n\u003cp\u003eA: The affected channel's current draw will spike to maximum limits, but the onboard multi-stage circuit isolation prevents the fault from migrating. The individual channel drops its valid data bit, flags an unmasked out-of-range sensor error code to the host DCS, while the remaining 15 analog loops continue operating without interruption.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 51309136-175 assembly be replaced while the system is powered up and active?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the termination card supports hot-swapping procedures under live 24 VDC backplane power. However, disconnecting the physical cable links from the active FTA to the I\/O processors will instantly interrupt signal updates for all 16 connected instrumentation loops, causing the host controller to immediately execute configured safe-state defaults.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":45121612677235,"sku":"MC-TAIH03 51309136-175","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-06-22_17-16-15_91c70f8f-08e4-4790-9578-674cdd52cc8f.png?v=1782119996","url":"https:\/\/www.dcssupplier.com\/ar\/products\/hoenywell-mc-taih03-51309136-175-analog-input-terminations","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
