Product Details：

Honeywell 51204168100 (51204168-100, MU-TAIY62) is a rack plug-in UCN analog input module for Honeywell Experion PKS DCS control system. It communicates with the C300 redundant controller through the UCN bus, and is specially used to collect 4-20mA analog signals transmitted from field instruments including pressure transmitters, flow transmitters, liquid level transmitters and temperature transmitters. The module converts the received current analog signals into digital data recognized by the controller, so as to realize real-time monitoring, closed-loop regulation and data recording of process parameters such as pressure, flow, liquid level and temperature. Each signal channel adopts independent isolation design and built-in RC filtering and surge suppression circuit, 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 damage. It is equipped with 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 measurement points. This analog input card 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 effectively reduces the shutdown risk of critical closed-loop control loops. It complies with Honeywell UCN bus communication protocol, and needs to be matched with MU-TAIY62 FTA termination assembly and MU-KFTS series shielded FTA cable to form a complete analog signal acquisition subsystem. It is a common spare I/O card for the transformation, expansion and daily maintenance of petrochemical, chemical, electric power and water treatment PKS systems, and is widely used in continuous process production occasions that require high-precision analog measurement.

Key specifications：MU-TAIY62 UCN analog input module for Honeywell Experion PKS,isolated 4-20mA input channels,built-in channel self-diagnosis and fault alarm,UCN bus communication 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 analog input module is widely deployed in petrochemical,chemical,power generation and water treatment plants for Honeywell Experion PKS DCS analog acquisition loop expansion,old input 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 closed-loop process measurement and regulation architecture. As a core unit for MU-TAIY62 analog input card and field transmitter signal acquisition carrier,it is the standard UCN analog input module for Experion PKS process control cabinet. Clearly marked channel terminals simplify field instrument wiring,loop trimming and regular diagnostic inspection work for control engineers.
