Product Description

The P0914XA and P0914XB are Fieldbus Rack assemblies that form the structural and communication backbone of the Foxboro I/A Series Distributed Control System (DCS). These racks provide the mechanical mounting platform and high-speed backplane required for Fieldbus Modules (FBMs) to interface with system processors.

Designed for high-density industrial I/O applications, the P0914XA (typically used as the primary rack) and the P0914XB (expansion rack) feature a shielded, noise-resistant architecture to maintain signal integrity in electrically harsh environments. Integrated power distribution and redundant communication paths help eliminate single points of failure in critical control loops.

Technical Specifications

Application

• Distributed Control Systems (DCS): Centralized mounting of FBMs for large-scale chemical and pharmaceutical plant automation.

• Redundant Network Architectures: Supports dual-path fieldbus communication for high-availability continuous processes.

• System Migration Projects: Enables I/A Series upgrades while preserving existing field wiring layouts.

FAQ

What is the primary difference between the P0914XA and P0914XB?
The P0914XA is typically used as the primary rack with main fieldbus cable termination, while the P0914XB functions as an expansion rack to increase I/O capacity.

Are Fieldbus Modules included with the rack?
No. The P0914XA and P0914XB include only the rack assembly and backplane. Fieldbus Modules and associated cabling must be ordered separately.
