Foxboro P0914XB – I/A Series Standard Redundant Processor Module

In stock

Product Introduction:
The Foxboro P0914XB is a standard redundant processor module for the Foxboro I/A Series Distributed Control System. The “P” denotes Processor, “0914” identifies the specific processor configuration (typically a dual-channel processor with moderate performance), and “XB” is the revision code indicating a mature, field-proven hardware generation. This module executes the control logic, manages I/O communication, and performs all safety calculations for the I/A Series controller. The P0914XB features dual-redundant architecture where two identical processors run in lockstep, comparing results every 100 milliseconds. It is the workhorse processor for medium-sized applications where ultra-high speed is not required but absolute reliability is mandatory. The “XB” revision is one of the most widely deployed processor revisions in the Foxboro I/A Series family, with a proven track record spanning decades of service in refineries, chemical plants, and power generation facilities.

Functional Features:
Dual Redundant Processors: Two processors run the same program simultaneously; hardware voter compares results every 100ms.
Reliable Performance: 100ms scan time is sufficient for most process control loops (temperature, pressure, flow, level).
Large I/O Capacity: Supports up to 1024 I/O points, suitable for medium-sized plants.
Dual Communication: Redundant Ethernet and serial paths ensure no single point of failure.
Online Diagnostics: Continuous self-testing with automatic fault detection and alarm reporting.
Hot Swappable: Can be removed and replaced while the system is running in a redundant configuration.
Fail-Safe Design: All outputs default to a safe state on loss of power or communication.

Application Scenarios:
Medium-Sized Refineries: Controls process units like crude distillation, catalytic cracking, and hydrotreating.
Chemical Plants: Manages batch processes and continuous processes with moderate I/O counts.
Water Treatment: Controls large treatment plants with hundreds of I/O points.
Pulp and Paper: Manages continuous process lines with reliable, proven hardware.
