CC-TCNT01 Honeywell C300 Controller IOTA Termination Assembly

CC-TCNT01 C300 Controller IOTA: Compact Termination Hub for Honeywell C300 Systems

The CC-TCNT01 is a C300 Controller Input Output Termination Assembly (IOTA) from Honeywell. It gives the C300 Controller module one clean connection point. All controller cable terminations land here: FTE, IO Link, Redundancy, Battery, and Time Source. The assembly also carries 24Vdc power to the controller module. At 0.311A and 24VDC, it stays within a low-load envelope. The unit suits cabinet-based C300 architectures that need tight, repeatable wiring. It is a strong fit for system integrators working with existing Honeywell C300 installations.

What This Assembly Connects

• FTE cable terminations for controller networking
• IO Link cable terminations for I/O communication
• Redundancy cable terminations for paired controller setups
• Battery cable terminations for backup power paths
• Time Source cable terminations for clock synchronization
• 24Vdc power feed to the C300 Controller module

Oiltech Controls’s Insight

Cabinet engineers often treat the IOTA as passive hardware. In practice, it defines cable routing quality and service access. The CC-TCNT01 groups five termination types on one assembly. That reduces loose wiring and shortens controller swap time. The 0.311A supply draw is low, so it will not stress existing 24VDC rails. For sites running C300 cabinets with mixed FTE and IO Link drops, this assembly is a practical field spare. It also helps when a legacy termination block fails and no drawing updates are available.

Oiltech Controls Review

Our bench checks focus on termination continuity and power path integrity. We confirm the 24Vdc distribution path and inspect connector seating across all five termination groups. The CC-TCNT01 arrives with clean contacts and no bent pins in our test flow. Engineers tell us the unit drops into existing cabinets without rework. That matters when a controller is down and the site needs a fast, verified replacement.

Professional FAQ

Q: Does the CC-TCNT01 include the controller module?

A: No. This listing covers the IOTA only. The C300 Controller module is a separate part.

Q: How do I confirm this IOTA matches my cabinet?

A: Check the spare part reference 51308307-175 against your drawing. Also confirm the five termination groups match your cable plan.

Q: From experience, what fails first on these assemblies?

A: Connector seating and cable strain points usually fail first. Inspect those areas before replacing the controller itself.

Q: Can I run this IOTA without a redundancy cable?

A: Yes, in simplex setups. Leave the redundancy termination unused and document the change in your cabinet drawing.

Q: How should I choose between surplus and refurbished units?

A: Pick refurbished when you want tested contacts and a verified power path. Pick surplus when budget is tight and the unit passes inspection. Both carry the same 12-month warranty.
