Honeywell CC-TAIM01
Product Name: Low-Level Analog Input IOTA (LLMUX Termination Assembly)
Product Overview: The CC-TAIM01 (part number 51305959-175) is a low-level analog input termination assembly (IOTA/baseplate) from Honeywell’s Experion PKS C300 Series I/O family. It serves as the physical termination interface for the CC-PAIM01 low-level analog input multiplexer (MUX) module, providing high-density field wiring for thermocouple (TC) and RTD temperature signals. It is a passive backplane that requires the active CC-PAIM01 module for full functionality.

Working Principle: The CC-TAIM01 is a passive baseplate providing mechanical and electrical termination for field thermocouple/RTD wiring. The active CC-PAIM01 module plugs into this baseplate, performing signal conditioning, multiplexing, and A/D conversion. Millivolt-level signals from TCs are routed through the IOTA to the MUX module with full galvanic isolation.
Application Scenarios: Dense temperature monitoring in process plants; PMIO (Process Manager I/O) systems within Experion PKS C300 architecture; suitable for control room environments with strong EMI immunity requirements.
Installation & Usage Notes:
- Install in a standard Series C I/O rack.
- The CC-TAIM01 MUST be paired with a CC-PAIM01 module – it is non-functional alone.
- Ensure proper cold junction compensation reference if required by the application.
- Maintain surge protection grounding per EN 61000-4-5.
- Verify channel-to-channel isolation before energizing.
