CC-TAIX01 | Honeywell | Module d’entrée analogique

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.
• Integrated Loop Power: Built-in 24 VDC distribution with short-circuit and current-limiting protections per channel.
• Modular Assembly: Facilitates redundant or non-redundant configurations with compatible active analog input modules.
• Secure Physical Termination: Industrial-grade screw clamp terminals provide strong resistance to mechanical vibration.
• Integrated Carrier Mounting: Clips directly to standard DIN rail mounting arrangements for simplified installation.

Industrial Applications

• Petrochemical & Refining: Interfacing pressure, flow, and temperature transmitters with the central Honeywell DCS.
• Power Generation: Continuous analog monitoring of auxiliary process variables and feedback loops.
• Water Treatment Facilities: Level, flow, and analytical chemistry transmitter integrations.
• Pulp & Paper Mills: Interfacing process instruments in high electrical noise environments.

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.
