CC-TCF901 51308301-175 Honeywell Control Firewall IOTA

The Honeywell CC-TCF901 51308301-175, also cataloged as the CC-TCF901 Control Firewall IOTA, operates as a dedicated hardware component for high-speed network traffic filtering and 24 VDC power routing within Experion C300 systems.

Hardware Specifications

Fault Tolerant Ethernet Network Integration

The CC-TCF901 provides dedicated network isolation and filtering across 8 Fault Tolerant Ethernet (FTE) access ports and 1 uplink interface. Designed for Experion C300 controller architectures, this firewall module prevents broadcast storms and unauthorized network packet propagation between cabinet-level controller nodes and supervisory networks. Internal power trace routing distributes regulated 24 VDC to adjacent control components while maintaining channel-to-channel signal isolation across high-speed data pathways.

Frequently Asked Questions

Q: What power input range is required for the CC-TCF901 51308301-175 module?

A: The module requires a nominal 24 VDC supply voltage with an acceptable operating tolerance range of +/- 10%.

Q: What is the specific port breakdown on the CC-TCF901 Ethernet interface?

A: The module is equipped with 9 total RJ-45 Ethernet interfaces, arranged as 8 dedicated Fault Tolerant Ethernet (FTE) local ports and 1 uplink connection.

Q: How is the CC-TCF901 physically mounted inside a control cabinet?

A: The hardware supports standard cabinet installation using either standard industrial DIN rail mounting or direct panel attachment.

Field Installation Guidelines

• Ethernet Cabling Limits: Use Category 5e or Category 6 shielded twisted-pair (STP) Ethernet cables for all FTE connections, ensuring individual cable segment lengths do not exceed 100 meters.
• Shield Earth Grounding: Ground all STP cable drain wires directly to the cabinet ground bar at a single entry point to prevent ground loop currents from interfering with high-speed data transmission.
• Power Distribution Wiring: Verify correct polarity of the 24 VDC input lines prior to energizing the bus. Maintain dedicated wire sizing according to maximum current draw for internal power distribution paths.
• Thermal Clearance: Mount the unit vertically with adequate top and bottom enclosure ventilation clearance to allow unobstructed natural convection cooling across the -20 to +70 deg C operating envelope.
