Product Description

The MU-TAOX12 (51304441-175) is a high-reliability Field Termination Assembly (FTA) designed for Honeywell Experion PKS and TDC 3000 process control systems. It provides the physical termination and signal conditioning interface between field-level discrete devices—such as switches, proximity sensors, and limit contacts—and the system’s Digital Input Processor (DIP / IOP).

Engineered for continuous industrial operation, the MU-TAOX12 simplifies cabinet wiring through an organized terminal layout while maintaining high signal integrity. Integrated isolation and surge protection help shield sensitive control electronics from electrical noise and transient events. This FTA is widely used in DCS maintenance, upgrades, and modernization projects, supporting reliable digital signal acquisition in power generation, refining, and chemical processing environments.

Frequently Asked Questions

Q: Is the MU-TAOX12 compatible with MC-series processors?
A: Yes. MU-TAOX12 and MC-TAOX12 variants share the same architectural framework and are commonly used with IOP / DIP cards for digital input signal processing.

Q: Does the MU-TAOX12 supply power to field contacts?
A: The FTA primarily manages signal termination and protection. Wetting voltage and field power depend on the associated controller, power distribution, and wiring configuration.
