Product Details：

Honeywell 51204164175 (51204164-175, MC-TAIY22) is the high-density conformal coated analog input FTA termination assembly matched with Honeywell MU-TAIY22 analog input IOP card for Experion PKS UCN I/O subsystem. Compared with the 51204164125 standard version, this FTA board integrates more analog signal channels in the same cabinet mounting space, suitable for process equipment with a large number of pressure, flow, liquid level and temperature transmitter points. It serves as the signal interface between the analog input module and field two-wire and four-wire 4-20mA transmitters, converting field analog signals into stable signals that can be identified by the UCN IOP card. Each channel is equipped with independent signal filtering circuit, surge suppression and channel isolation components, which can effectively filter high-frequency interference and transient pulse noise generated by frequency converters and high-power equipment in industrial sites, reduce signal fluctuation and measurement drift, and maintain the precision of closed-loop regulation. The PCB surface adopts conformal coating protection, which can resist moisture, salt mist and corrosive gas in harsh working environments such as chemical plants and offshore platforms, reduce the risk of circuit corrosion and short circuit and extend the service life of the termination board. It adopts reliable screw terminal layout, and each channel is clearly marked with signal positive, negative, auxiliary power and shielding grounding points, which is convenient for loop wiring, single-point calibration and fault inspection during commissioning and maintenance. It connects to the matched MU-TAIY22 IOP card through MU-KFTS series shielded FTA cable, the overall shielding structure greatly improves the anti-interference ability during long-distance analog signal transmission. It follows the standard rack installation dimension of Honeywell PKS Series C cabinet and can be installed on the cabinet backplane together with the analog input IOP card. It can feed back loop open circuit, power loss and signal abnormal status information to the Experion operation station through the IOP card, helping maintenance personnel quickly locate faulty measurement points. It is a key supporting termination spare part for Honeywell Experion PKS DCS large-scale analog acquisition system construction, high-density signal expansion and harsh environment cabinet transformation projects.

Key specifications：High-density coated analog input FTA assembly for MC-TAIY22,24VDC auxiliary power supply,multi-channel isolated 4-20mA signal input,built-in filtering and surge suppression,conformal coated PCB,shielded cable connector. Operating temperature range is -10°C to +60°C. It supports continuity test, insulation inspection and loop signal calibration test during maintenance troubleshooting.

This analog input FTA assembly is widely deployed in petrochemical,chemical,power generation and water treatment plants for Honeywell Experion PKS DCS analog process signal centralized acquisition,old termination board replacement and spare stocking projects. It cooperates with Honeywell C300 redundant controller,redundant UCN network and MU-TAIY22 analog input card to build high-stability closed-loop process measurement and regulation architecture. As a core unit for MC-TAIY22 coated AI FTA board and field transmitter signal carrier,it is the high-channel-count supporting termination assembly for PKS UCN analog input subsystem. Clearly marked signal terminals simplify field instrument wiring,loop trimming and regular coating aging inspection work for control engineers.
