Honeywell MU/MC-TAOX12 51304441-175 Analog Output FTA Module

Product Description

The MC-TAOX12 (Part Number: 51304441-175) is a 16-channel Analog Output Field Termination Assembly (FTA) designed for Honeywell HPM, TDC 3000, and Experion PKS platforms. It provides a reliable interface between I/O processors and field devices, distributing precise 4–20 mA signals for actuators, control valves, and positioners.

Built for high-availability industrial environments, the MC-TAOX12 supports redundant I/O processor connections, ensuring continuous process control even during module maintenance or processor failover. Its precision components maintain signal integrity over long cable runs, making it ideal for refineries, chemical plants, and power generation facilities.

Technical Specifications

Application Scenarios

• Driving 4–20 mA control valves in continuous process loops

• Providing setpoints for Variable Frequency Drives (VFDs) in pumping and motor control applications

• Interfacing with I/P transducers for pneumatic actuator operation

• Replacing or upgrading legacy AO FTAs in TDC 3000 to Experion migration projects

Frequently Asked Questions

What is the difference between MU-TAOX12 and MC-TAOX12?
The MU prefix typically indicates a standard board, while MC denotes a conformal-coated board suitable for high-humidity or corrosive environments. The core functional part number (51304441-175) is identical.

Does this board include 250-ohm precision resistors?
No. The MC-TAOX12 is an Analog Output board and drives current loops. Precision resistors are not required, unlike Analog Input (HLAI) modules.
