Overview
The Honeywell CC-TCNT01 51308307-175, also cataloged as the CC-TCNT01 Input/Output Termination Assembly, provides physical and electrical termination for field wiring within the Honeywell Experion PKS Series C architecture. It interfaces with C300 Controller and Series C I/O hardware to organize field signal connections and provide controlled signal pass-through.

Series C Signal Termination and Wiring Interface
The CC-TCNT01 terminates field wiring at the I/O interface and maintains an organized connection between external process wiring and Series C control hardware. Therefore, technicians can route field conductors through a defined termination point instead of connecting individual field wires directly to the controller assembly.
The assembly supports physical signal pass-through and wiring distribution within the Series C architecture. However, the supplied data does not specify individual channel counts, signal ranges, input/output isolation ratings, or supported field protocols. Those parameters should therefore be confirmed against the applicable I/O module and system configuration before installation.
For process instrumentation using protocols such as 4-20 mA HART, FOUNDATION Fieldbus, or Profibus PA, the termination assembly should be evaluated together with the corresponding Series C I/O module. The CC-TCNT01 data supplied here does not establish protocol support independently.
Frequently Asked Questions (FAQ)
Q: Does the CC-TCNT01 provide signal conversion?
A: The supplied specifications identify the CC-TCNT01 as an Input/Output Termination Assembly. They do not specify an independent analog-to-digital, digital-to-analog, or protocol conversion function.
Q: Can the CC-TCNT01 operate independently of a Series C I/O module?
A: The assembly interfaces with Honeywell Series C I/O hardware and the C300 Controller architecture. Its termination function depends on the associated system hardware for actual signal processing.
Q: What installation information should technicians verify before wiring?
A: Technicians should verify the applicable I/O module terminal assignment, field signal type, wiring polarity, shielding method, grounding arrangement, and permitted cable routing before connecting field conductors.
Field Installation Guidelines
- Confirm the CC-TCNT01 model and part number before installation. Match CC-TCNT01 and 51308307-175 with the approved system documentation.
- Isolate the applicable control-system power and field circuits before connecting or removing field wiring.
- Install the termination assembly on the specified DIN rail or Series C mounting arrangement. Maintain sufficient cabinet clearance for wiring access and inspection.
- Route signal cables separately from high-voltage power conductors and high-current switching circuits. Use appropriate segregation for low-level process signals.
- Terminate cable shields according to the approved Honeywell system grounding design. Avoid creating unintended ground loops through multiple shield termination points.
- Verify every conductor against the applicable I/O channel assignment before energizing the circuit. Check polarity and terminal identification for each field connection.
- Inspect terminal connections for correct seating and mechanical retention. Do not apply excessive force to terminal blocks, connectors, or cable harnesses.
- Before commissioning, perform continuity and insulation checks where required by the site electrical procedure. Then verify field signal behavior through the associated Series C I/O module.
