Product Details：Honeywell 51204170150 (51204170-150, MC-TAIH22) is the conformal coated high-level analog input module of Honeywell Experion PKS UCN I/O series. It is different from the 4-20mA dedicated MU-TAIY62 series module, this card supports multiple high-level analog signal types including DC voltage signals, 4-20mA current signals, RTD and thermocouple signals on process sites, and can collect measurement signals from transmitters, temperature sensors and other analog instruments at the same time. It communicates with the C300 redundant controller through the UCN bus protocol, converts field analog signals into digital data, and uploads the process variable data to the controller to realize closed-loop regulation and data recording of pressure, flow, liquid level and temperature. The PCB surface adopts conformal coating treatment, which can resist moisture, salt mist and corrosive gas in harsh industrial environments such as chemical plants and offshore platforms, reduce the risk of circuit corrosion and short circuit, and improve the environmental adaptability of the module. Each channel is equipped with independent isolation circuit, signal filtering and surge suppression components, which can filter high-frequency noise and transient pulse interference introduced by long field cables, isolate abnormal voltage impact from the field side, and protect the backplane and controller mainboard from permanent damage. The module integrates complete channel self-diagnosis function, which can detect loop open circuit, signal loss, over-range and communication timeout faults, and upload alarm information to the Experion operation station for maintenance personnel to quickly locate abnormal measuring points. It supports hot swap operation under lockout-tagout maintenance procedures, maintenance personnel can replace the faulty module directly without cutting off the power supply of the whole cabinet, which reduces the shutdown risk of critical continuous process loops. It complies with Honeywell UCN bus communication protocol, and needs to be matched with MC-TAIH22 FTA termination assembly and MU-KFTS series shielded FTA cable to form a complete multi-type analog signal acquisition subsystem. It is a key spare I/O card for Honeywell Experion PKS DCS multi-signal mixed acquisition system transformation, harsh environment cabinet upgrade and daily maintenance projects, widely used in petrochemical, chemical, power and water treatment process control occasions.

Key specifications：MC-TAIH22 UCN high-level analog input module for Honeywell Experion PKS,24VDC auxiliary power supply,multi-signal compatible input,built-in channel self-diagnosis and fault alarm,conformal coated PCB,UCN bus compatible,supports hot swap. Operating temperature range is -10°C to +60°C. It supports channel signal test, communication handshake inspection and over-range alarm verification during maintenance troubleshooting.

This high level analog input module is widely deployed in petrochemical,chemical,power generation and water treatment plants for Honeywell Experion PKS DCS mixed analog signal acquisition expansion,old single-type AI card replacement and spare stocking projects. It cooperates with Honeywell C300 redundant controller,redundant UCN network and matched FTA termination board to build high-stability multi-variable process measurement and regulation architecture. As a core unit for MC-TAIH22 coated high-level AI card and multi-type field instrument signal acquisition carrier,it is the multi-purpose UCN analog input module for Experion PKS process control cabinet. Clearly marked channel terminals simplify field instrument wiring,loop trimming and regular coating aging inspection work for control engineers.
