Description
Providing the critical physical and electrical link between field instruments and the system controller, the Honeywell CC-TAIX01 serves as a high-density 16-channel Analog Input Input-Output Termination Assembly (IOTA) for the Experion C300 Series C platform. This module distributes loop power to process transmitters, collects continuous 4-20mA signals, and routes them to active C300 processing modules. Designed for high reliability in process automation architectures, it ensures clean signal integrity and robust physical cable termination in industrial control panels.
Key Features
-
High Density Channel Support: Terminations for up to 16 analog input channels configured in differential or single-ended modes.

Empirical Engineering Insights
Alternative Models & Compatibility
The CC-TAIX01 is a non-conformal coated assembly. For deployment in environments with corrosive atmospheric contaminants, specifying the conformal coated alternative (CC-TAIX11) is required to meet ISA G3 standards. This termination assembly is designed specifically to host the CC-PAIX01 or CC-PAIX02 active Series C modules and cannot accept Series A or other legacy input modules.
Application Pitfalls & Engineering Notes
When mixing 2-wire (loop-powered) and 4-wire (externally-powered) instruments on the same assembly, incorrect grounding can lead to common-mode voltage saturation. For 4-wire configurations, ensure that signal-minus (-) paths are not left floating; connect them directly to the common ground plane of the enclosure power supply to prevent erroneous drift readings.
Commissioning & Wiring Tips
To eliminate high-frequency electromagnetic noise interference, always terminate the shielding drain wire of input cables on the dedicated chassis ground bus of the CC-TAIX01 IOTA. Never ground the shield at both the field transmitter end and the IOTA termination end simultaneously, as this can introduce destructive ground loops.
Installation & Field Deployment Guidelines
CRITICAL WARNING:
Isolate and lock out all auxiliary 24 VDC power networks prior to mounting or completing any wiring terminations on the assembly. Hot-wiring transmitter loops on an energized assembly can blow on-board terminal protective fuses or disrupt active controller communication backplanes.
1
Mount the CC-TAIX01 board directly onto the 35mm DIN rail inside the enclosure, ensuring the carrier locks are fully engaged.
2
Connect the system safety ground strap to the designated low-impedance ground point on the carrier.
3
Route field cables through clean, non-obstructive wiring ducts and strip lead wires back exactly 7 mm before inserting into the clamp terminals.
4
Torque the terminal clamp screws to a maximum rating of 0.5 Nm to prevent physical thread damage on the termination block.
