Channel-to-Channel Isolation and FTE Network Interface

The CC-TCF901 is designed as an FTE (Fault Tolerant Ethernet) interface assembly within the Honeywell control system architecture. The module provides nine Ethernet RJ-45 connections, with eight ports allocated for in-cabinet controllers and Series CFIM connections and one uplink connection to the supervisory FTE network.

The unit supports fiber-optic interface expansion through compatible CA-FSMx01 single mode and CA-FMMx01 multi-mode fiber modules. The 24 VDC distribution interface supplies connected control network components while maintaining defined electrical separation between communication paths.

For process control installations, Honeywell network interface assemblies are commonly integrated with distributed control system components requiring structured Ethernet communication. Signal segregation and channel-to-channel isolation practices should be maintained during system design to minimize communication interference.

Frequently Asked Questions (FAQ)

Q: How many Ethernet connections are available on the CC-TCF901?
A: The CC-TCF901 provides nine RJ-45 Ethernet connections. Eight ports connect to in-cabinet controllers and Series CFIMs, while the ninth port provides the FTE supervisory network uplink.

Q: Does the CC-TCF901 directly support fiber-optic communication?
A: The CC-TCF901 supports fiber-optic connectivity through compatible CA-FSMx01 FTE Single Mode Fiber Modules and CA-FMMx01 FTE Multi-Mode Fiber Modules.

Q: What power supply is required for the CC-TCF901?
A: The module requires a 24 VDC supply and provides 24 VDC power distribution for connected control components. The specified supply rating is 0.30 mA @ 24 VDC.

Field Installation Guidelines

• Install the CC-TCF901 on the designated control cabinet mounting surface according to Honeywell system installation requirements.
• Verify that the 24 VDC supply polarity and grounding connections comply with the cabinet power distribution design.
• Maintain separation between Ethernet communication cables and high-voltage power conductors to reduce electrical interference.
• Use appropriate shield grounding practices for Ethernet and fiber conversion assemblies where applicable.
• Confirm RJ-45 cable routing and port assignments before commissioning the FTE network connection.
• Inspect fiber module installation points and ensure optical interfaces remain protected from contamination during field installation.
