Woodward 5466-1245 CPU5200 Enhanced MicroNet Control CPU

Product Description

The 5466-1245 CPU5200 Enhanced Processor is a high-performance control module developed by Woodward for use in MicroNet-Plus and MicroNet TMR control platforms. Designed as the primary execution unit, this processor handles deterministic real-time logic, internal communications, and system coordination in safety-critical and mission-critical rotating equipment applications.

This Cyber Ready processor is engineered for environments where operational continuity, redundancy, and cybersecurity compliance are mandatory. The module is mechanically and logically fixed to Slot A1 in MicroNet-Plus systems and operates exclusively without Ethernet interface modules, ensuring architectural integrity and predictable performance.

Core Functionality Overview

The 5466-1245 CPU module acts as the central intelligence layer of the control system, executing closed-loop algorithms, sequencing logic, protection routines, and inter-module messaging. In TMR configurations, it supports synchronized redundant processing to eliminate single points of failure.

Key operational responsibilities include deterministic task scheduling, real-time data arbitration between I/O subsystems, and fault-tolerant system supervision across simplex or redundant installations.
