The Honeywell CC-TCNT01 is widely used within industrial process control environments that employ Honeywell’s Experion PKS and Series C300 Distributed Control Systems (DCS). This module is essential in complex automation settings such as chemical plants, oil refineries, power generation stations, and manufacturing facilities where precise and reliable connection points for controller modules and field devices are crucial. The CC-TCNT01 acts as the physical interface facilitating the termination and distribution of signals between the controller and field instrumentation, ensuring robust communication and power delivery.
Industries rely on the Honeywell CC-TCNT01 in scenarios where effective management and isolation of electrical noise and transient disturbances are critical to maintaining system stability and protecting sensitive controller components. This module supports analog and discrete signals, handling inputs from sensors and outputs to actuators, thereby enabling comprehensive real-time monitoring and control tasks. Its role in managing cable terminations for various crucial connections, including redundancy, battery, and time source, provides a structured backbone for high-availability automation systems.
Product Introduction and Positioning
The Honeywell CC-TCNT01 is an Input/output Termination Assembly (IOTA) designed specifically for use with Honeywell’s C300 Controller modules within the Experion PKS platform. It serves as a critical hardware component that consolidates cable terminations — including field terminal enclosures (FTE), I/O links, backup power sources, and synchronization signals — into a single, clean interface assembly. This centralization simplifies installation, troubleshooting, and maintenance.

As a vital part of the modular architecture, the CC-TCNT01 ensures that power distribution (24 V DC) and signal isolation are efficiently handled, protecting the controller module and enhancing system performance. It is positioned for engineers and system integrators who prioritize reliable physical layer connectivity as part of their automation design, especially when implementing redundant or non-redundant C300 control configurations.
The ergonomic design and compatibility with field wiring standards make the CC-TCNT01 a preferred choice for managing the physical layer of communication and power within Honeywell’s large-scale process control systems.
Key Technical Features and Functional Benefits
The Honeywell CC-TCNT01 includes 8 analog and discrete input channels supporting signal ranges from 0–10 V and 4–20 mA for analog, and 0 V to 24 V AC/DC for discrete channels. This flexibility accommodates various sensor and actuator types within control infrastructures. Its excellent 2500 V AC signal isolation capacity safeguards controllers from surges and noise, ensuring signal integrity and system protection.
Mechanically, the module is compact with roughly 120mm width, 80mm height, and 40mm depth and weighs about 1 kg, making it easy to integrate into control cabinets without sacrificing durability. Designed to operate effectively over a broad temperature range (-40 to +85 °C), the CC-TCNT01 withstands harsh industrial environments.
The module’s role extends beyond mere physical connection; it also distributes 24 V DC power to the controller module and manages critical communication cables including redundancy links and time source synchronization. Optional features such as LED diagnostics and fuse protection per channel promote maintenance efficiency and system uptime.

Installation Notes and Maintenance Best Practices
When installing the Honeywell CC-TCNT01, it is important to ensure proper cable routing and strain relief within control cabinets. The termination assembly should be mounted securely with adequate clearance to allow for easy connection of redundancy, FTE, battery, and time source cables. Grounding and shielding techniques are crucial to minimize noise interference and safeguard signal integrity in electrically noisy environments.
Maintenance practices should include periodic inspection of terminal connections for corrosion or looseness and verifying the health of fuse protections if installed. Ensuring clean, tight connections helps prevent signal loss or intermittent faults. Regular testing of redundancy circuits and time source synchronization signals contributes to system reliability and uptime.
