Honeywell CC-TCNT01 C300 Controller Input Output Termination Assembly

The Honeywell CC-TCNT01 is a C300 Controller Input Output Termination Assembly (IOTA) designed to provide the physical interface between the C300 controller and associated system cabling. It serves as the central termination point for controller communications, redundancy connections, battery interfaces, time synchronization links, and power distribution, supporting the installation and operation of Honeywell Experion PKS control systems.

Controller Interface and Termination Functions

CC-TCNT01 provides all major cable termination points required by the C300 controller assembly. It supports the connection of Fault Tolerant Ethernet (FTE) networks, I/O Link communications, controller redundancy cabling, battery connections, and external time source interfaces.

By consolidating these connections onto a dedicated termination assembly, the module simplifies controller installation and cable management within the control cabinet.

Power Distribution

The assembly distributes 24 V DC power to the connected C300 controller module. This allows field power to be terminated at a single location before being routed to the controller hardware.

The specified supply rating of 0.311 A at 24 V DC provides a reference for system power planning and cabinet load calculations.

System Integration

CC-TCNT01 is designed specifically for Honeywell C300 controller architectures used within the Experion PKS platform. As an IOTA, it does not perform control processing itself; instead, it provides the electrical and mechanical interface required for controller operation and communication connectivity.

Correct matching of the termination assembly and controller hardware is important when replacing or expanding an existing C300 installation.

Technical Specifications

Installation Considerations

The termination assembly should be installed as part of a compatible Honeywell C300 controller arrangement. All communication, redundancy, battery, and time synchronization cables should be connected to their designated termination points according to the system design documentation.

Because the assembly serves as the controller's primary connection interface, the correct cable routing and termination arrangement should be verified during maintenance and replacement activities.

Frequently Asked Questions

Q: What is the primary purpose of the CC-TCNT01?
A: CC-TCNT01 acts as the termination and distribution assembly for a Honeywell C300 controller, providing connection points for communication, redundancy, battery, time source, and power wiring.

Q: Does CC-TCNT01 perform control processing?
A: No. The assembly is an IOTA and does not execute control logic. Processing functions are performed by the connected C300 controller module.

Q: What connections are terminated on the CC-TCNT01?
A: The assembly provides termination points for FTE network connections, I/O Link communications, redundancy cables, battery connections, time source interfaces, and controller power distribution.
