Honeywell CC-TCF901 9-Port Control Firewall IOTA

The Honeywell CC-TCF901 is a 9-port Control Firewall Input/Output Termination Assembly (IOTA) for connecting in-cabinet controllers and Series CFIMs to the Fault Tolerant Ethernet (FTE) network. Eight Ethernet ports connect to controllers and CFIMs, while the ninth port provides an uplink to the supervisory network. The assembly also distributes 24 VDC power to the control system.

Functional Overview

The CC-TCF901 provides Ethernet connectivity between control equipment and the FTE supervisory network. Its nine RJ-45 connections separate the eight controller-side connections from the single supervisory uplink, defining the physical network connection arrangement described in the supplied product information.

The IOTA also provides 24 VDC power distribution to the control equipment. Fiber-optic connectivity is associated with the listed CA-FSMx01 single-mode and CA-FMMx01 multimode FTE fiber modules; verify the required fiber interface and configuration before selecting accessories.

Technical Specifications

Network and Configuration Considerations

The eight controller-side ports and the supervisory uplink serve different connection roles. When identifying a replacement or planning a control cabinet installation, confirm the port assignment, FTE topology, and interface requirements against the existing system configuration.

The source lists both single-mode and multimode fiber modules. These refer to different optical transmission media and should not be treated as interchangeable without confirming the fiber type, optical interface, and supported system configuration.

Installation and Associated Hardware

The CC-TCF901 is the termination assembly for the Honeywell CF9 Control Firewall. Honeywell documentation identifies the CC-PCF901 as the Control Firewall module that mounts on the IOTA. The assembly is intended for the Series C cabinet configuration; the separate DC-TCF901 is identified for Series C Mark II cabinets. Confirm the cabinet generation and mounting interface before ordering a replacement.

Frequently Asked Questions

Q: What is the difference between the CC-TCF901 and CC-PCF901?

A: The CC-TCF901 is the Input/Output Termination Assembly (IOTA), which provides the physical connections and power distribution. The CC-PCF901 is the Control Firewall module mounted on the IOTA. They are separate components and should not be treated as the same part.

Q: Can the CC-TCF901 connect to a fiber-optic FTE network?

A: The supplied product information lists the CA-FSMx01 single-mode and CA-FMMx01 multimode FTE fiber modules. Select the module according to the installed fiber type and verify the exact ordering code against the applicable Honeywell documentation.

Q: Is the CC-TCF901 interchangeable with the DC-TCF901?

A: Do not assume direct interchangeability. Honeywell documentation identifies the DC-TCF901 for Series C Mark II cabinet mounting, while the CC-TCF901 is listed for the Series C cabinet configuration. Verify the cabinet and backplane requirements before replacement.
