Honeywell CC-TCF901 CF9 IOTA Module 51308301-175 Rev J1

Honeywell CC-TCF901 CF9 IOTA Module 51308301-175 REV J1

Honeywell CC-TCF901 is a specific 9-Port Control Firewall Input/Output Termination Assembly (IOTA) only for the Honeywell Experion Process Knowledge System (PKS) C300 infrastructure. The CF9 IOTA provides a secure network segmentation boundary for common industrial and offshore marine automation enclosures to isolate vital control networks from disruptive traffic.

This termination assembly isolates in-cabinet control gear such as C300 controllers and Series C Fieldbus Interface Modules (FIMs) from the larger supervisory networks. It handles traffic priority and enables consistent DC power distribution, ensuring uninterrupted operation in processing settings where network outages or delays are unacceptable.

Model Details & Identification

• Model Name/Number: CC-TCF901
• Manufacturer Product Number (MPN): 51308301-175
• Revision Level: REV J1
• Module Type: Control Firewall 9-Port (CF9) Input/Output Termination Assembly (IOTA)

Technical Details

Key Features

1. Firewall Protection at the Hardware Level – The system automatically discards non-essential broadcast packets and unauthorised Ethernet packets before they burden internal C300 controller processors.
2. Dedicated Fault Tolerant Ethernet (FTE) Pathing: 8 protected downlink ports for intra-cabinet redundancy with a prioritised 9th port uplink to supervisory level 2 network.
3. Integrated Power Distribution – No more messy auxiliary terminal strips. Feed continuous 24VDC loops right through the board traces to power linked control gates.
4. Flexible Media Adaptation: Provides onboard integration choices for single-mode (to 15 km) and multi-mode fiber-optic SFP modules for long-distance connectivity across marine bulkheads.
5. Industrial Grade Form Factor: Designed with very robust, marine-capable PCB coverings to endure constant temperature cycles and environmental moisture.

Our Engineer’s Guide and Tips:

When deploying the CC-TCF901 in maritime environments or coastal processing zones, network storming at the supervisory level is your primary threat. The CF9 infrastructure is purposefully built to prevent these external storms from flooding the C300 execution environment.

Tips for Installation and Extended Operational Life:

1. Uplink Saturation Safeguard: The 9th port features internal queue prioritizing. It is intentionally engineered to give priority to downlink traffic if the fabric becomes saturated. Ensure your primary controller telemetry uses ports 1 through 8.
2. Fiber Modules Current Draw: If adding optional optical modules (CC-FSMX01 or CC-FMMX01), allow for an extra 0.30 mA per module at 24VDC when calculating your cabinet’s total power budget and heat dissipation limits.
3. Mounting Integrity: Marine vibrations can cause subtle fret corrosion on ground contacts. When fastening the IOTA to the Series C carrier rail, confirm that the grounding clips mate cleanly with the bare metal surface of the carrier channel to avoid intermittent grounding faults on your FTE lines.
