Features:
- Terminates eight analog output circuits for the PAOX03 architecture.
- Supports the specified redundant size-B termination arrangement.
- Uncoated MU construction with compression field terminals.
MU-TAOX12 is the uncoated Honeywell field termination used for an eight-output PAOX03 analog arrangement with redundancy. Compression terminals connect the field loops, while the processor cables link the termination to the installed output hardware. Honeywell distinguishes this size-B board from the smaller TAOX02 nonredundant layout and the screw-terminal TAOX52 option. The catalog identity includes 51304335-100, which should be compared directly with the complete supplied assembly label rather than shortened to the family name.
For compatible PAOX03 operation, the published normal output range is 4-20 mA, with 750 ohms maximum resistive load at 22 mA. The redundant TAOX12 table specifies different disturbance durations for swap and failover: four milliseconds maximum during a swap and 125 milliseconds maximum during failover. These system figures do not mean that the termination alone provides a complete redundant output system. Check the processor paths, field receiver response, uncoated-board suitability and the 307.3 mm by 120.65 mm mounting footprint before service.
The MU-TAOX12 51304335-100 Honeywell Uncoated Redundant Analog Output Termination may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
TAOX12 is the redundant eight-output termination arrangement in the manufacturer matrix. It uses a larger size-B footprint than TAOX02 and must be matched to the configured PAOX03 processor paths. The presence of the FTA alone does not prove that a complete redundant processor pair is installed.
For the PAOX03 and TAOX12 combination, Honeywell specifies a normal 4-20 mA signal, a directly accessible 0.1-21.4 mA range and a maximum output current of 26 mA. Distinguish the normal control range from these extended and limiting values when checking the field receiver.
Field wiring uses compression terminals on the uncoated board. Keep each loop conductor identified and restore the approved polarity and shielding after service. Check that the cabinet environment permits the MU construction and that the phone-style processor cable matches the installed termination assembly.
