Honeywell 8C-TCNT01 / 8U-TCNT01 / 51307032-175 – C300 Controller Input/Output Module | Experion PKS Platform
Engineering Background
The Honeywell 8C-TCNT01 (also catalogued as 8U-TCNT01, part number 51307032-175) is a dedicated I/O interface module engineered for the Honeywell C300 Controller within the Experion PKS (Process Knowledge System) distributed control architecture. Designed to meet the rigorous demands of continuous-process industries, this module serves as the critical bridge between field instrumentation and the C300 controller’s processing core, enabling deterministic, high-integrity signal acquisition and command output.
Product Positioning
Procurement engineers specifying replacement or expansion I/O capacity for Experion PKS installations will find the 8C-TCNT01 the authoritative OEM solution. Its plug-and-play compatibility with existing C300 controller racks eliminates re-engineering overhead, while its proven field reliability supports both brownfield upgrades and greenfield DCS deployments across refining, petrochemical, power generation, and pharmaceutical sectors.

System Architecture & Signal Flow
Within the Experion PKS architecture, the 8C-TCNT01 occupies a dedicated slot in the C300 Controller rack. Field signals are wired to I/O Link-connected Series C I/O modules; the 8C-TCNT01 manages the I/O Link communication between those field modules and the C300 controller’s execution engine. Processed data is then propagated over the Fault Tolerant Ethernet (FTE) network to the Experion Server for historian archiving, advanced control, and operator display. This layered architecture ensures that field-level signal integrity is maintained end-to-end from sensor to supervisory HMI.

Technical FAQ
Q: Is the 8C-TCNT01 compatible with the C200 or C200E controller?
A: No. This module is designed exclusively for the C300 controller rack. C200/C200E installations require different I/O interface modules.
Q: Can this module operate in a redundant C300 controller pair?
A: Yes. The 8C-TCNT01 supports redundant C300 configurations; both primary and secondary controllers share the I/O Link network managed by this module.
Q: What is the difference between 8C-TCNT01 and 8U-TCNT01?
A: These are alternate catalog designations for the same module used across different Honeywell regional and revision documentation sets. The OEM part number 51307032-175 is the definitive cross-reference.
Q: Is a firmware upgrade required when replacing an existing module?
A: Firmware revision compatibility should be verified against the installed C300 controller firmware version using Honeywell Control Builder. Contact Konmask support for guidance on specific revision matching.
Q: What warranty is provided?
A: Konmask provides a 90-day functional warranty on all modules. Extended warranty and exchange programs are available — contact us for details.
