Features:
- Provides sixteen instrument termination circuits for redundant HLAI/STI use.
- Compression-terminal size-B arrangement for compatible PM I/O processors.
- Uncoated MU execution with resistor-limited transmitter power conditioning.
The MU-TAIH12 field termination assembly provides sixteen connections for high-level analog input or Smart Transmitter Interface circuits in the Honeywell PM I/O architecture. Honeywell lists this arrangement for redundancy, with compression field terminals and a size-B footprint. The supported processor pairings are defined in the compatibility matrix; the terminal board itself does not perform analog conversion or decide which transmitter communication service is available in the installed control system.
The uncoated MU construction distinguishes this listing from the corresponding coated MC assembly. Its published board length and width are 307.3 mm and 120.65 mm. When used for the documented HLAI function, the system supports the specified voltage ranges or a 4-20 mA signal through 250 ohms, with resistor-limited transmitter power conditioning. Preserve the approved common reference, shielding and redundant cable connections during replacement, and confirm the complete 51304337-100 label rather than inferring assembly interchangeability from the base model alone.
The MU-TAIH12 51304337-100 Honeywell Redundant HLAI and STI Termination Assembly may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell MU-TAIH12 51304337-100 official technical documentation and product links.
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.
Trace the sixteen instrument circuits and the redundant processor cable destinations before disconnecting this FTA. Keep field wire identification separate from the processor-side connector labels. Correct channel numbering is essential because a mechanically compatible connection does not establish that the instrument is mapped to the intended control point.
The HLAI pairing accepts the documented voltage ranges or 4-20 mA through a 250-ohm path. The installed processor and field circuit determine the active measurement configuration. Do not infer current-input wiring or transmitter supply requirements from the generic description of an analog termination board.
The MU version is uncoated and uses a size-B mounting footprint. Check the cabinet environment and the approved hardware list before substituting it for a coated assembly. Allow sufficient access to compression terminals and processor connectors, without using board dimensions as packed shipping dimensions.
