Honeywell TC-FCCN01 ControlNet Gateway Adapter

The Honeywell TC-FCCN01, also cataloged as the TC-FCCN01 ControlNet Gateway Adapter, operates as a dedicated hardware component for deterministic network interfacing within C300 controller systems. Configured for non-redundant ControlNet media configurations, the adapter manages high-speed data frame transfer between local backplane logic and remote field devices or peer controllers. It converts parallel internal bus signals into serial ControlNet bit streams over fiber optic or RG-6 coaxial cabling.

Hardware Specifications

Cold Junction Compensation & Signal Isolation

The Honeywell TC-FCCN01 features a 500 VAC isolation barrier between external user power and the internal Flexbus backplane, suppressing common-mode noise and ground loop propagation across networked channels. While primary functions handle deterministic protocol transmission, connected analog I/O modules leverage backplane signal regulation to preserve sensor measurement integrity, including thermocouple cold junction compensation (CJC) accuracy and 4-20 mA HART loop processing across the C300 architecture.

Frequently Asked Questions

Q: How much current can the TC-FCCN01 supply to adjacent modules via the Flexbus?

A: The module supplies a maximum output of 640 mA at 5 VDC across the local Flexbus backplane to power up to 8 expansion I/O modules.

Q: What are the physical media and connector options for the ControlNet port?

A: The adapter supports Belden RG-6/U Quad Shield coaxial cable or fiber optic cabling utilizing user-selectable SC or ST connectors.

Q: Can the TC-FCCN01 be deployed in a redundant ControlNet media configuration?

A: No, the TC-FCCN01 is specifically engineered for non-redundant ControlNet network topographies.

Field Installation Guidelines

1. Mount the TC-FCCN01 firmly onto the mounting rail and verify mechanical retention clips are secured before applying power.
2. Connect 24 VDC external power wiring (19.2 to 31.2 VDC range) to the designated supply terminals, observing strict polarity.
3. For coaxial runs, terminate using RG-6/U Quad Shield cable with standard BNC connectors; for fiber optic runs, route through SC or ST connectors avoiding bend radii tighter than manufacturer limits.
4. Ensure the overall cable shield and chassis ground wire connect directly to the cabinet main bonding point to prevent RF interference.
5. Limit expansion modules to a maximum of 8 units on the Flexbus to ensure current draw remains within the 640 mA at 5 VDC limit.
