Honeywell CC-PCF901 Control Firewall Module

The Honeywell CC-PCF901, also cataloged as the CC-PCF901 Control Firewall Module, operates as a dedicated hardware component for Field Termination Enclosure cable distribution and network node interfacing within Experion PKS platforms.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel Isolation

The module manages network communications while operating alongside 4-20 mA HART loop protocol instruments and Experion PKS control loops. Built-in channel-to-channel isolation barriers protect internal network nodes from ground potential differences, common-mode noise, and voltage transients originating in field wiring. Furthermore, integrated cold junction compensation (CJC) maintains thermal stability across adjacent Series C Field Interface Modules during continuous process data exchange.

Frequently Asked Questions

Q: What primary function does the CC-PCF901 module execute within the control cabinet?

A: The module serves as a central connection point that distributes Field Termination Enclosure cables to multiple Series C Field Interface Modules and in-cabinet network nodes.

Q: On which assembly does the control firewall module mount?

A: The unit mounts directly onto the CF9 Input/Output Termination Assembly (IOTA) inside the system cabinet.

Q: What are the electrical supply requirements for powering the module?

A: The module operates from a 24 VDC power supply, drawing a nominal current of 0.112 A.

Field Installation Guidelines

Ensure cabinet power feeds are fully de-energized before mounting the module onto the designated CF9 IOTA. Align the hardware enclosure with the mounting pins and secure it firmly using the provided retaining screws to establish reliable chassis grounding. Route Ethernet and FTE network cables through dedicated internal wire management ducts, maintaining physical separation from high-voltage power lines to prevent electromagnetic interference.
