Product Details：

Honeywell 51204160125 (51204160-125, MU-TDIY22) is the matched digital input FTA termination assembly for Honeywell Experion PKS MU-TDIY22 digital input IOP card. It serves as the signal transfer interface between the digital input module and field discrete devices including limit switches, proximity sensors, push buttons and dry contact interlock switches. This FTA board adopts multi-channel isolated wiring design, each channel is equipped with built-in surge and transient suppression components, which can filter interference pulses from field cables and avoid instantaneous high voltage impact damaging the UCN digital input card. It uses screw terminals for convenient field wiring, all channels are clearly marked with channel number, common terminal and alarm signal point, which is convenient for single-point loop inspection and signal calibration during commissioning and maintenance. It is equipped with dedicated shielded cable interface, connected to the MU-TDIY22 IOP card through MU-KFTS series shielded FTA cable, effectively improving anti-interference performance in industrial sites with many frequency conversion equipment. It follows the standard rack installation size of Honeywell PKS Series C cabinet, can be installed on the backplane together with the matched digital input IOP module. It can feed back channel open circuit and power abnormal status information to the Experion operation station through the IOP card, helping maintenance personnel quickly locate faulty points. It is a necessary supporting termination spare part for Honeywell Experion PKS DCS interlock signal acquisition, cabinet transformation and system expansion projects, widely used in petrochemical, chemical, power and water treatment process control occasions.

Key specifications：Digital Input FTA termination assembly for MU-TDIY22,24VDC rated working voltage,multi-channel isolated dry contact input,built-in transient suppression,shielded cable connector. Operating temperature range is -10°C to +60°C. It supports continuity test, insulation inspection and channel signal verification during maintenance troubleshooting.

This digital input FTA assembly is widely deployed in petrochemical,chemical,power generation and water treatment plants for Honeywell Experion PKS DCS discrete signal acquisition distribution,old termination board replacement and spare stocking projects. It cooperates with Honeywell C300 redundant controller,redundant UCN network and MU-TDIY22 digital input card to build high-stability process interlock and status monitoring architecture. As a core unit for MU-TDIY22 DI FTA termination board and field discrete signal carrier,it is the standard supporting termination assembly for PKS UCN digital input subsystem. Clearly marked channel terminals simplify field wiring,loop calibration test and regular aging inspection work for control engineers.
