Product Overview

The Honeywell CC-TCF901 (PN: 51308301-175) is a 9-port Control Firewall IOTA for Experion PKS Series C. It provides the physical mounting and electrical interface for the CC-PCF901 Control Firewall module, isolating the C300 controller network from higher-level supervisory traffic.

The module also acts as a traffic arbiter on the Fault Tolerant Ethernet (FTE) network, ensuring critical control messages are prioritized. It delivers robust 24 VDC power to the firewall module and connected control devices, maintaining high system availability in mission-critical environments.

Technical Data

Key Features:

• Advanced Network Isolation: Dedicated uplink separates control traffic from supervisory network.

• Flexible Media Options: RJ-45 ports standard; supports optional single-mode or multi-mode fiber.

• Streamlined Power Distribution: Backplane delivers 24 VDC to firewall and connected devices.

• Rugged Industrial Design: G3 coating protects against moisture and chemical vapors.

Typical Applications

• Distributed Control Systems (DCS): Connect C300 controllers and Series C I/O to FTE backbone.

• Remote Instrument Enclosures: Secure network gateway with optional fiber uplinks.

• Cyber-Hardened Control Zones: Electronic security perimeter meeting ISA/IEC 62443 requirements.

• High-Availability Networks: Redundant FTE where single cable failure must not disrupt control.

FAQ

Q1: Relationship between CC-TCF901 and CC-PCF901?
A1: CC-TCF901 is the IOTA/baseplate; CC-PCF901 is the firewall module that plugs into it. Both are required for firewall protection.

Q2: Can all 9 ports connect to C300 controllers?
A2: No, 8 ports are downlink for local devices; 1 port is reserved as uplink to the supervisory FTE network.

Q3: Does it support fiber-optic connections out of the box?
A3: Standard ports are RJ-45 copper. Fiber is supported via optional SFP modules (CC-FSMX01 or CC-FMMX01).

Q4: What does the G3 rating mean?
A4: The -175 suffix indicates G3 conformal coating, protecting against corrosion from sulfur, salt, and other airborne contaminants in harsh industrial atmospheres.
