Foxboro P0400HH – I/A Series High-Speed Redundant Processor Module

In stock

Product Introduction:
The Foxboro P0400HH is a high-speed redundant processor module for the Foxboro I/A Series Distributed Control System. The “P” denotes Processor, “0400” identifies the 400 Series processor family, and “HH” indicates the high-performance (HH) revision with enhanced processing speed and memory. This module is the brain of the I/A Series controller, executing the control logic, managing all I/O communication, and performing the safety and control calculations for the entire system. The P0400HH features true dual-redundant architecture with two processors running in lockstep, comparing results every scan cycle. If one processor fails, the other takes over instantly with zero data loss. The “HH” revision offers faster scan times (as low as 50ms) and larger memory (up to 64MB) compared to standard P0400 modules, making it suitable for large, complex control applications.

Functional Features:
Dual Redundant Processors: Two processors run the exact same program simultaneously; hardware voter compares results every 50ms.
High-Speed Execution: 50ms scan time enables fast control loops for turbine governors and pressure control.
Large Memory: 64MB RAM supports complex applications with thousands of control loops and data points.
Dual Communication: Every processor has two independent communication paths to every I/O module.
Online Diagnostics: Continuous self-testing of CPU, memory, communication, and I/O with automatic fault detection.
Hot Swappable: Processor modules can be removed and replaced while the system is running with zero impact.
Fail-Safe Design: All outputs default to a safe state upon loss of power or communication.

Application Scenarios:
Large Power Plants: Controls entire boiler islands or turbine auxiliaries where processing speed is critical.
Oil Refineries: Manages multiple process units (distillation, cracking, reforming) from a single processor.
Chemical Plants: Executes complex control logic for reactors, columns, and storage tanks.
Pulp and Paper: Manages continuous process lines where any downtime results in significant production loss.
