- Provides 16 analog output field circuits for PAOY22 processors.
- Supports the specified redundant and standby-manual arrangements.
- Uses compression terminals on a 307.3 mm-long size-B board.
Honeywell MU-TAOY22 is the compression-terminal field assembly for 16 analog outputs associated with the PAOY22 I/O processor family. The manufacturer ordering table expressly restricts this FTA to that processor family. Its provision for redundant operation and standby-manual connection is part of the documented output arrangement; it is not a self-contained controller or an analog output processor. The MU model is the uncoated version, distinct from the coated MC offering.
Output replacement work needs to account for the field device as well as the cabinet hardware. Record the installed processor pair, output assignments and any standby-manual wiring before disturbing the termination. The size-B board is 307.3 mm long by 120.65 mm wide and differs from the screw-terminal TAOY52 option. Maintaining an output during processor maintenance requires the complete approved manual-control arrangement and procedure; a standby-manual connector by itself does not guarantee uninterrupted control of the process.
The MU-TAOY22 51204172-125 Honeywell Analog Output Termination Assembly 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 assembly terminates 16 analog output circuits for PAOY22 processors. Match every loop to the field device and the configured channel before reconnection. The FTA does not independently set output range, accuracy or fail behavior; those depend on the processor and the installed control configuration.
A standby-manual connection is supported in the documented TAOY22 arrangement. Establish which manual station, cables and operating procedure are actually installed before relying on it during maintenance. Do not assume the connector means that the process output can be interrupted or transferred safely without an approved plan.
Honeywell specifies TAOY22 for PAOY22 processors only. Verify both processor identities in a redundant installation and preserve the existing cable arrangement. Similar analog-output channel counts are not evidence that a PAOX-family processor or another termination can be used in its place.
