Product Identification
51308307-175 is the component part number for the Honeywell CC-TCNT01, a critical Input/Output Termination Assembly (IOTA) designed for the Experion PKS C300 controller system. It serves as the passive, high-reliability backplane and physical mounting base for the active C300 controller modules (CC-PCNT01) and associated I/O modules.
The CC-TCNT01 IOTA functions as a "system backbone" within the Series C hardware architecture, providing mechanical support, power distribution, and signal routing between the controller, I/O modules, and the FTE (Fault Tolerant Ethernet) network. It eliminates the need for separate power supplies and complex field wiring by integrating power and signal bus connections into a single standardized baseplate.
The assembly is designed for high availability with support for redundant controller configurations. It is crucial to note that this is the carrier/baseplate (the "socket"), not the controller itself. The active C300 controller module (CC-PCNT01) is purchased separately and plugged into this base.
- Honeywell Experion PKS Series C
- Passive IOTA / Backplane
- 4-slot capacity (2 controllers + 2 I/O)
- Supports redundant controller pairs
- Mounts on 35mm DIN rail or panel

Functions
Core functions
- Physical mounting carrier — Provides a standardized, secure base for up to 4 modules, including C300 controllers (CC-PCNT01) and associated I/O modules, in a compact 4-slot form factor.
- Power distribution — Integrates 24 VDC power distribution directly through the backplane, eliminating the need for separate terminal strips and reducing installation complexity.
- Signal interface & routing — Provides a clean, organized interface between the active modules and the FTE (Fault Tolerant Ethernet) network, I/O links, and ControlNet communications.
Diagnostics & support
- Redundancy support — Supports 1:1 controller redundancy for high availability. In a redundant pair, one controller can be replaced while the system remains operational.
- Integration diagnostics — Built-in status detection contacts can report power and communication status back to the DCS, enabling remote troubleshooting and maintenance scheduling.
- Hot-swap capability — In a redundant controller pair configuration, a module can be replaced online without system interruption.
Applications
The CC-TCNT01 IOTA is a foundational component in process control applications where the Experion PKS C300 system is deployed.
Lifecycle
Active currently in production — fully supported
Product status: The CC-TCNT01 (51308307-175) remains an active, supported product in Honeywell's Series C I/O portfolio. It continues to be the recommended IOTA for new C300 installations and system expansions.
Spare parts & support: Replacement units and accessories are available through Honeywell's standard support channels and authorized distributors. The Series C architecture is designed for long‑term availability.
Replacement & migration:
- Verify the exact part number (51308307-175) and revision for drop-in compatibility.
- Ensure total system power is disconnected before replacing the IOTA.
- For redundant systems, verify the IOTA supports the required redundancy configuration.
Recommendation: For new Experion PKS C300 installations, the CC-TCNT01 IOTA remains the recommended baseplate solution. For existing systems, having spare units available is advisable.
