CC-PAIM01 — Honeywell Series C Low-Level Temperature Multiplexer (LLMUX)
CC-PAIM01 is not a standard 16-channel 4–20 mA analog input card. Honeywell documents it as the Series C PMIO low-level multiplexer IOP: it collects thermocouple, millivolt, and RTD measurements through proven PMIO field termination assemblies. HKXY Instruments is a China industrial automation trader with 15 years of export experience, not the OEM. We help buyers verify the exact code, FTA mix, and IOTA before quotation.

How the temperature multiplexer is built
Per Honeywell Experion Series-C I/O Specification EP03-490-520, low-level inputs use Honeywell PMIO LLMUX FTAs. Each FTA supports 16 channels. Two FTA styles are documented:
- Mx-TAMR04 (also listed as MU-TAMR04 in the detailed multiplexer table) — 16 RTD inputs
- Mx-TAMT04 — 16 thermocouple or millivolt inputs
- Mx-TAMT14 — 16 TC/mV inputs with remote cold-junction reference
Any combination of those FTAs may be used so a cabinet can mix TC, mV, and RTD points. Temperature points are scanned at a fixed 1 second rate (up to 64 channels/s maximum as documented). All TC inputs are cold-junction compensated. Open thermocouple detection (OTD) can be configured so the open-sensor check occurs before the PV is propagated.
Documented LLMUX specifications
| Parameter | Specification |
|---|---|
| Input type | Thermocouple and/or RTD (plus millivolt via TC FTA) |
| Isolation | 64 fully isolated channels — channel-to-channel, channel-to-PM, and channel-to-power-supply common — in 16-channel increments |
| Nominal TC range | −20 to +100 mV |
| Channel bandwidth | 0 to 4.7 Hz (−3 dB) |
| Non-damaging continuous input | TC: −10 to +10 V; RTD: −1 to +2 V at 100 mA |
| Gain error (−20 to +100 mV) | 0.050% full scale maximum |
| Temperature stability | ±20 ppm/°C max for TC/mV and RTD |
| Long-term drift | 500 ppm |
Do not confuse with high-level analog input
CC-PAIN01 and CC-PAIH* modules accept 4–20 mA high-level signals on 16 channels. CC-PAIM01 is the temperature multiplexer path. Ordering the wrong IOP leaves the PMIO FTAs unmatched and the C300 database unable to map the points.
RFQ checklist
- Photograph the CC-PAIM01 nameplate and the CC-TAIM01 IOTA label.
- List every FTA model in the chain (TAMR04 / TAMT04 / TAMT14), cable lengths, and whether remote CJR is used.
- Record sensor types (TC type or RTD curve), quantity of points, and whether OTD is enabled.
- Note cabinet position, redundancy expectations, and Experion database export if available.
- Quantity, destination, and required date. Stock, price, and lead time remain [TO CONFIRM].

FAQ
How many temperature points can one CC-PAIM01 support?
Up to 64, built from up to four 16-channel PMIO LLMUX FTAs.
Can one module mix RTD and thermocouple inputs?
Yes. Honeywell allows any combination of the documented RTD and TC/mV FTAs to create the required mix.
What IOTA must be ordered with it?
CC-TAIM01, the 6-inch PMIO LL Mux IOTA. The electronics module and IOTA should be treated as one assembly during replacement.
Is the scan time the same as a high-level AI card?
No. The LLMUX PV update is documented as 1 second, including the optional open-thermocouple check — much slower than a 50 ms high-level analog input scan.
Can you publish a live stock count or list price here?
No. Availability and commercial terms are [TO CONFIRM] after label verification.
Request pricing, inspection, and lead time
Include FTA models and a nameplate photo so we can quote the correct CC-PAIM01 assembly rather than a high-level AI lookalike.
