The CC-TCF901 serves as the physical termination and mounting platform for the CC-PCF901 Control Firewall module within Honeywell Experion PKS Series C architectures. Specifically, this IOTA acts as the network convergence point for Fault Tolerant Ethernet (FTE) cabling inside the cabinet. It routes eight downlink connections from in-cabinet controllers and Series CFIMs while dedicating the ninth RJ-45 port as an uplink to the supervisory network. Furthermore, the assembly distributes 24VDC power to the associated control components, simplifying cabinet wiring and reducing external power supply requirements. The unit carries the CC prefix, indicating conformal coating for enhanced environmental protection.
The CC-TCF901 provides a standardized Ethernet interface for critical control network infrastructure. Its port allocation follows a strict design logic to maintain network segmentation and reliability.
The module features 9 RJ-45 connections in total. Eight ports serve as FTE cable connections for in-cabinet controllers and Series CFIMs. Meanwhile, the 9th port functions exclusively as the uplink to the FTE supervisory network. This separation ensures that supervisory traffic remains distinct from intra-cabinet control traffic.
Power distribution occurs directly through the IOTA at a supply rating of 24VDC. For installations requiring optical isolation or extended distance, the assembly supports optional fiber-optic modules. Specifically, it accommodates the Ca-FSMx01 Single Mode Fiber Module and the Ca-FMMx01 Multi-Mode Fiber Module. These modules share a low supply rating of 0.30mA at 24VDC.
The mounting footprint measures approximately 12.1 cm x 14.5 cm (L x W). This compact form factor allows installation on the Series C carrier without consuming excessive cabinet space.
The CC-TCF901 is designed for installation within the controlled environment of a Series C cabinet. The CC-prefix designation confirms that the printed wiring board carries a conformal coating. Consequently, the assembly resists humidity, airborne contaminants, and minor temperature fluctuations common in industrial control rooms. Additionally, the passive termination design minimizes heat generation, relying solely on the 24VDC distribution for connected active modules. The unit mounts directly onto the Series C carrier rail, ensuring mechanical stability and proper grounding through the chassis connection.
Proper installation of the CC-TCF901 requires careful attention to FTE network topology and cable separation. First, verify that the mating Control Firewall module is the CC-PCF901, as the IOTA functions solely as the mounting and termination base. Next, secure the IOTA to the Series C carrier using the designated mounting hardware.
When wiring the Ethernet connections, route the eight FTE downlink cables from the controllers and CFIMs to ports one through eight. Meanwhile, connect the supervisory network cable to the designated 9th uplink port. Crucially, Honeywell documentation warns against mixing FTE A and FTE B link cables on the same IOTA, as this can cause communication conflicts. Furthermore, verify the 24VDC power input polarity before energizing the assembly. Finally, if optional fiber modules are used, confirm that the single-mode or multi-mode module type matches the installed optical cabling infrastructure.

Q1: What is the primary difference between the CC-TCF901 and the CC-PCF901?
A1: The CC-TCF901 is the termination assembly (IOTA) that provides mounting and physical connections. In contrast, the CC-PCF901 is the active Control Firewall module that plugs into this IOTA.
Q2: How many devices can connect to the CC-TCF901 directly?
A2: The assembly provides 8 downlink RJ-45 ports for controllers and CFIMs. Additionally, it offers 1 uplink port for supervisory network connectivity.
Q3: Does this IOTA support fiber-optic communication natively?
A3: The base IOTA uses copper RJ-45 connections. However, it supports optional Ca-FSMx01 (single-mode) or Ca-FMMx01 (multi-mode) fiber modules for optical uplinks or downlinks.
Q4: What is the supply rating specified for the fiber module options?
A4: The compatible fiber modules operate at a supply rating of 0.30mA at 24VDC. This low current draw ensures minimal impact on the cabinet power budget.
Q5: How does the CC-TCF901 handle power distribution?
A5: The assembly distributes 24VDC directly to the connected control components through the IOTA backplane interface, eliminating the need for separate power wiring to each module.
