- Provides eight analog output field termination circuits.
- Listed with the MC-PAOX03 processor in the compatibility matrix.
- Compact size-A construction with compression field terminals.
The Honeywell MU-TAOX02 is an eight-circuit analog output field termination assembly used with the MC-PAOX03 processor in the PM I/O compatibility matrix. It provides compression terminals for field wiring and uses the phone-connector style identified in the manufacturer ordering table. Its role is the physical output termination, rather than the signal-processing or control algorithm. Output range, accuracy and operating behavior should therefore be taken from the compatible processor and the configured system, not invented as independent FTA ratings.
This is the compact size-A, nonredundant arrangement, measuring 152.4 mm long by 120.65 mm wide. The larger TAOX12 termination addresses a different redundancy configuration, and the TAOY family belongs to a different output processor architecture. Record the installed field loop assignments, processor cable and any manual-control arrangement before service. The uncoated MU construction must also match the cabinet environmental requirement; a similar coated assembly should only be selected after the full mechanical and electrical configuration is checked.
The MU-TAOX02 51304476-125 Honeywell Analog Output Field Termination may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: This excerpt retains the original Honeywell IO03-500 cover, applicable model tables, electrical specifications and their footnotes. It is a historical specification, not a current lifecycle notice. Match the complete assembly label and installed processor before replacement.
The eight field circuits belong to the PAOX03 analog output arrangement. Confirm the processor and field loop assignments before transferring wires. Do not use the FTA terminal count as evidence of output accuracy or range, and do not confuse this board with the sixteen-output PAOY family.
Honeywell distinguishes TAOX02 from the larger TAOX12 redundant termination. The compact size-A board is not a direct mechanical equivalent of the size-B option. Review the existing processor arrangement, FTA cables and mounting space before proposing a change between the two layouts.
After replacement, verify each affected loop against the configured output assignment and the receiving field device. Check polarity and the approved control response using the site commissioning procedure. A successful processor diagnostic does not establish that the field wiring and actuator response are correct.
