P0916DC
Product Name
Foxboro P0916DC FBM (Fieldbus Module) Terminal Cable
Product Description
The Foxboro P0916DC is a terminal cable that serves as a crucial connection component within the Foxboro I/A Series Distributed Control System (DCS). This cable is specifically designed to interface between Fieldbus Modules (FBMs) and their corresponding termination assemblies (TAs), or directly to field devices in some configurations.
The “DC” in the part number, along with the common association with a 3-meter length, indicates a specific type of cable used for maintaining digital communication line balance. It includes internal components (often referred to as “Baluns”) that are essential for preventing near-end crosstalk when HART transmitters are connected to FBM loops that are powered from a common external power supply. This ensures the integrity and reliability of communication signals in complex industrial environments. Loops using the FBM’s internal power source typically do not require these Balun cables.
It’s a passive component that plays a vital role in ensuring clear and stable data transmission for various I/O signals within the I/A Series architecture, contributing to the overall performance and reliability of the control system.
