Product Introduction
The HONEYWELL CC-TAIM01 is the PMIO LLMUX IOTA used in Honeywell C300 / Experion PKS systems to interface low-level thermocouple and RTD signals into the CC-PAIM01 LLMUX module. It does not operate as a standalone analog input card; it is the IOTA/terminal interface that routes field signals through the LLMUX architecture, where channel-to-channel and channel-to-power isolation are required.
This board is typically found in temperature-intensive process applications such as furnaces, reactors, reformers, boilers, and turbine inlet monitoring. Because the CC-TAIM01 depends on the CC-PAIM01 processor module and the correct FTA wiring, compatibility must be confirmed against the Honeywell I/O list, cabinet wiring drawings, and FTA part numbers before procurement.
QA/QC Transparency SOP
- Intake & Origin Verification
Confirm full part number CC-TAIM01, revision, serial number, and source. Reject units with damaged IOTA connectors, cracked terminal blocks, or missing revision labels. - Visual & Connector Inspection
Inspect FTA ribbon connectors, backplane pins, terminal screws, and isolation barriers. Corrosion or bent pins on LLMUX IOTAs can mimic channel faults. - Continuity & Isolation Testing
Verify channel-to-channel and channel-to-ground isolation using a calibrated insulation tester. Check for shorts between adjacent TC/RTD channels. - Functional Verification with CC-PAIM01
Where possible, test with a compatible CC-PAIM01 module and known FTA. Verify channel scanning, open-circuit detection, and stable readings across multiple 16-channel groups. - Final QC & Anti-Static Packaging
Label with test date, revision, and condition grade. Pack in anti-static bags with FTA connector protection. Include nameplate, connector, and terminal photos for traceability.
Field Engineer Gotchas
- CC-TAIM01 is not a standalone AI module.
It requires the CC-PAIM01 LLMUX module. Ordering only the IOTA without confirming the processor module and FTA is a common procurement error. - FTA mismatch breaks channel mapping.
MC-TAMR and MC-TAMT FTAs serve different sensor types. Using the wrong FTA can cause incorrect scaling, open-circuit alarms, or reversed channel assignments. - 64 channels are grouped in 16-channel blocks.
If one 16-channel group fails, the fault may appear localized to a specific FTA cable, connector, or isolation block rather than the entire IOTA. - TC millivolt signals are noise-sensitive.
Poor shielding, broken twisted pairs, or ground loops can create drifting readings that look like module failure. Verify field wiring before replacing the IOTA. - Do not assume direct interchangeability with other CC-TAxx IOTAs.
CC-TAIX01, CC-TAOX01, and CC-TAID01 serve different signal types. CC-TAIM01 is specific to low-level multiplexed TC/RTD applications.

Application Scenarios
- Furnace temperature monitoring.
Multiple thermocouple inputs are consolidated through the CC-/CC- architecture. A failed IOTA can cause lost temperature points across one or more 16-channel groups. - Reformer or reactor bed temperature profiling.
High-channel-count TC arrays benefit from LLMUX density. Replacement planning must include FTA type, cable harness integrity, and channel calibration records. - C300 system spare pool build.
Plants running CC- modules should keep at least one verified CC- spare if temperature inputs are critical to safety, interlocks, or advanced control. - Real-world case (anonymized).
A petrochemical plant reported 16 TC channels reading open after a cabinet maintenance activity. The CC- module was healthy. Root cause: the CC- FTA ribbon connector was partially seated. Resolution: reseated the connector, verified isolation, and restored channel scanning.
FAQ
It is the PMIO LLMUX IOTA for low-level analog inputs. The actual processing is handled by the CC- module; CC- provides the terminal/isolation interface.
How many channels does it support?
64 fully isolated channels, organized in 16-channel groups.
What sensors does it support?
Thermocouple and RTD inputs through compatible FTAs such as MC-TAMR04 and MC-TAMT04.
Can I replace it without shutting down the controller?
Honeywell PMIO IOTAs are often designed for hot-swap within supported procedures, but do not assume this for your cabinet. Follow site-approved maintenance and redundancy procedures before removing any IOTA.
What should I check before buying a surplus unit?
Request nameplate photos, revision confirmation, FTA connector condition, isolation test results, and confirmation that it matches your CC- module and FTA type.
Does it work with C200 and C300 controllers?
It belongs to the Honeywell C300 / Experion PKS PMIO I/O family. Compatibility with specific controller generations should be verified against the project I/O configuration.
