Honeywell CC-PAIM01 51405045-175 Analog Input Module

The Honeywell CC-PAIM01 51405045-175 is a low-level analog input multiplexer (LLMUX) module for the Experion® PKS Series C I/O system. Designed to interface directly with thermocouples and RTDs, it processes weak millivolt signals from temperature sensors without requiring external signal conditioners. The module delivers up to 64 isolated channels (in 16-channel increments) and integrates seamlessly with the CC-TAIM01 termination assembly, providing high-density, precision temperature monitoring for critical process applications in refining, petrochemical, and power generation industries.

Recommended Alternative Models

Model Number	Description	Key Differences
CC-TAIM01	Termination (IOTA) base for CC-PAIM01	Required mating base; not a module substitute
CC-PAIX02	4-20mA HART High-Level Analog Input	Cannot read mV thermocouple signals; for standard 4-20mA process inputs with HART
CC-TAIM01 51305959-175	LLMUX IOTA Termination Assembly	Termination base variant for 64-channel configuration
MC-PAIH03	TDC3000 HPM Analog Input Module	Legacy TDC3000 platform; not cross-compatible with Experion Series C

Critical Compatibility Note: The CC-PAIM01 is designed for low-level millivolt signals (TC/RTD) and must be paired with the CC-TAIM01 IOTA base. It cannot read 4-20mA signals or standard analog process inputs—these require the high-level CC-PAIX02 module.

Frequently Asked Questions (FAQ)

1: What signal types can the CC-PAIM01 51405045-175 accept?

A: The module is designed for low-level signals only: thermocouples (B/E/J/K/N/R/S/T types), RTDs (Pt100, 2/3/4-wire), and millivolt signals from strain gauges or other low-output sensors. It cannot directly accept 4-20mA or 1-5V signals—those require a high-level input module like CC-PAIX02.

2: What is the maximum channel count and how is it configured?

A: The module supports up to 64 fully isolated channels, configured in 16-channel increments via CC-TAIM01 termination assemblies (FTAs). Each FTA provides 16 channels for either TC/mV inputs or RTD inputs, and any combination can be used to create the desired channel mix.

3: What is the scanning speed and accuracy?

A: The full module scan cycle is 100 ms fixed, with per-channel software filters adjustable from 1–100Hz. Accuracy is ±0.05% FS at 25°C and ±0.1% FS across the full operating temperature range.

4: Can this module be replaced without shutting down the system?

A: Yes. The CC-PAIM01 supports hot-swap replacement without powering down the rack. However, it is recommended to bypass the corresponding control loops before removal to avoid process disturbances.
