Honeywell CC-TCF901 51308301-175 Control Firewall Module
Configured for secure, high-speed network isolation and power routing in Experion C300 platforms, the Honeywell CC-TCF901 (CC-TCF901 Control Firewall Module) provides direct physical/electrical execution. This 9-port hardware module establishes dedicated cabinet-level network segmentation for real-time Fault Tolerant Ethernet (FTE) traffic while concurrently distributing regulated 24 VDC auxiliary power to adjacent control hardware components.

Channel-to-Channel Isolation and 4-20 mA HART Interface Architecture
The CC-TCF901 network interface architecture employs galvanic channel-to-channel isolation across all physical RJ-45 Ethernet lines to prevent ground loop noise from degrading high-speed control communications. Within Experion C300 system enclosures, this firewall module segregates low-level sensor signals, such as 4-20 mA HART loop protocols and Foundation Fieldbus/Profibus PA segments, from high-density supervisory networks. Internal power trace topologies ensure stable 24 VDC bus routing to connected control cards, maintaining common-mode voltage rejection limits across harsh industrial EMC conditions.
Frequently Asked Questions
Q: Can the CC-TCF901 module be hot-swapped while the Experion C300 controller chassis is energized?
A: Yes, hot-swapping is permitted provided the cabinet installation adheres to standard Honeywell live-insertion guidelines, ensuring power bus pins mate after frame ground contacts are fully established.
Q: How are the 9 RJ-45 Ethernet ports partitioned for control traffic?
A: Ports 1 through 8 are dedicated to local Fault Tolerant Ethernet (FTE) connections for in-cabinet controllers and Series CFIM modules, while Port 9 operates strictly as an isolated uplink to the supervisory FTE network.
Field Installation Guidelines
- Ensure the 35 mm DIN rail or panel mounting surface is grounded directly to the primary cabinet safety earth bus before securing the module chassis.
- Maintain a minimum vertical clearance of 50 mm above and below the housing to facilitate natural convection airflow across the rated operating temperature range of -20 deg C to +70 deg C.
- Terminate all Ethernet cables using shielded RJ-45 connectors (STP CAT5e or CAT6) with shield drain wires bonded to the cabinet ground at a single entry point to eliminate ground loops.
- Verify incoming supply power reads within the specified 24 VDC +/-10% voltage tolerance at the terminal block before energizing internal module power distribution channels.
