Product Details：

Honeywell 51204174175 (51204174-175, MC-TAOY52) is the conformal coated high-density analog output FTA termination assembly for Honeywell Experion PKS UCN I/O system, which is the harsh-environment upgraded version compared with MU-TAOY52 51204174125. It is designed to match the MC-TAOY52 analog output IOP card, acting as the signal transfer interface between the I/O module and field analog regulators, including control valve positioners and electric actuators that rely on stable 4-20mA current signals for closed-loop regulation. The PCB circuit board adopts conformal coating protection, which can resist moisture, salt mist and corrosive gas in chemical plants and offshore platforms, effectively reducing the risk of circuit oxidation, leakage and short circuit and maintaining stable performance under long-term severe working conditions. This FTA assembly supports 16 channels of 4-20mA analog control signals, and each channel is equipped with independent signal buffering circuit and surge suppression components. It can filter high-frequency noise and transient pulse interference brought by long field cables, block reverse voltage impact from the actuator side, and protect the precision output circuit of the matched IOP card from permanent damage. It adopts reliable compression screw terminal structure, every terminal position is clearly marked with signal positive, signal negative, auxiliary power and shielding grounding points, which is convenient for technicians to complete loop wiring, signal range trimming and fault troubleshooting during factory commissioning and daily maintenance. It connects to the supporting analog output IOP card through MU-KFTS series shielded FTA cable, the shielding structure greatly reduces electromagnetic interference in control cabinets with a large number of frequency converters and high-power equipment. It follows the standard rack installation dimension of Honeywell PKS Series C cabinet and can be installed side by side with the IOP module on the termination rack. This FTA can feed back loop open circuit, load loss and signal abnormal alarm information to the Experion operation station through the IOP card, helping maintenance staff quickly locate abnormal pressure, flow, liquid level and temperature regulation loops and cut down system downtime. It supports redundant I/O configuration, when the primary channel fails, the secondary channel can take over the control task to improve the safety of critical process loops. It is widely used in petrochemical, chemical, power generation and water treatment automation projects, commonly used for closed-loop control system construction, harsh environment cabinet upgrade, control loop expansion and old standard FTA board replacement. It is an essential supporting accessory to guarantee the linearity and stability of 4-20mA regulating signals in continuous production processes.

Key specifications：MC-TAOY52 analog output FTA assembly,24VDC auxiliary power,16-channel 4-20mA output,built-in surge suppression and signal buffering,conformal coated PCB,shielded connector,supports redundant configuration. Operating temperature range: -10°C to +60°C. It supports continuity test, insulation test and output trimming calibration during maintenance.

This conformal coated analog output FTA assembly cooperates with Honeywell C300 redundant controller,redundant UCN network and MC-TAOY52 analog output card to build stable redundant closed-loop process regulation architecture.
