Features:
- Honeywell names 8C-TAIM01 as a coated 6-inch PMIO LLMux IOTA.
- The manufacturer pairs it with 8C-PAIM01 and separate TC/RTD field assemblies.
- 8U-TAIM01 is listed separately as uncoated hardware.
The October 2011 Honeywell PlantCruise Series 8 specification lists the 8C-PAIM01 low-level multiplexer IOM and 8C-TAIM01 coated IOTA together. Its system table includes MC-TAMT04 thermocouple and MC-TAMR04 RTD FTAs, while the detailed page labels 8C-TAIM01 as the coated IOTA PWA in a 64-point arrangement. It separately identifies 8U-TAIM01 as uncoated. The source therefore establishes component identity and architecture; it does not imply that the IOTA alone converts thermocouple values or determines a field sensor's wiring and measurement accuracy.
For procurement, identify the plant's Series 8 cabinet, actual LLMux IOM, IOTA label and revision, FTA types, interconnecting cables, sensor wiring and system release. The manufacturer-authored document confirms 8C-TAIM01 but not extra website number 51306999-175. Check that number against the supplied physical item or Honeywell parts record. Before authorized service, record baseline values and diagnostics, follow site isolation and current manufacturer guidance, then verify affected temperature channels and communication through the complete IOM/IOTA/FTA path. Do not transfer specifications from newer or differently coated low-level multiplexer hardware without exact compatibility evidence.
The 8C-TAIM01 51306999-175 Honeywell Series 8 Low-Level Multiplexer IOTA may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell 8C-TAIM01 51306999-175 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.
Honeywell identifies 8C-TAIM01 as the coated 6-inch low-level multiplexer IOTA. The same table lists 8U-TAIM01 as uncoated hardware, so these executions should not be merged. The IOTA is distinct from the electronic 8C-PAIM01 IOM. Check the installed cabinet, position, coating and physical part label before selecting a spare.
The Honeywell architecture pairs the low-level multiplexer IOM and IOTA with separate thermocouple or RTD field termination assemblies. The 64-point system description is not a claim that the IOTA independently samples or calibrates sensors. Confirm FTA type, cable route, actual sensor wiring and configured point assignments before maintenance. Apply signal and timing data only to the documented complete system.
The manufacturer-authored PDF prints exact 8C-TAIM01 and its PMIO LLMux IOTA role, but does not map website number 51306999-175. Verify that number and the supplied revision from a physical label or Honeywell parts record. The source is a 2011 PlantCruise specification on a third-party mirror; current release and installed-system compatibility should be checked separately before commissioning.
