WOODWARD 5466-1047 | MicroNet TMR CPU5200 Controller

Description

Product Overview

The WOODWARD 5466-1047 is a CPU5200 processor module used in Woodward MicroNet TMR turbine control systems and the 5009FT platform. Woodward documentation identifies it as a PowerPC5200 400 MHz CPU with application software, intended for triple-modular-redundant control architectures. It provides the processing platform required to execute turbine control logic and coordinate system-level monitoring and control functions.

This module is particularly relevant to steam turbine, gas turbine, and compressor control applications where continued operation and fault tolerance are important. As a controller-level spare, it can be valuable when maintaining an installed MicroNet TMR system and avoiding extended downtime caused by processor failure. Personally, I would verify the installed coder, firmware, application version, and chassis configuration before replacement rather than treating processor compatibility as a simple part-number match.

Technical Specifications — 5466-1047

Woodward’s current product-change documentation lists this processor for MicroNet TMR and 5009 applications, with Coder compatibility in the 5.04–5.08 range. The same documentation classifies it as a non-preferred legacy CPU for new installations.

Key Features and Benefits — 5466-1047

• CPU5200 processing platform for MicroNet TMR control architecture.
• Designed for applications requiring redundant turbine-control processing.
• PowerPC5200 processor operating at 400 MHz.
• Supplied with application software according to the applicable configuration.
• Suitable as an installed-system replacement or maintenance spare.
• Supports legacy MicroNet TMR installations where the existing application remains compatible.
• Helps maintenance teams reduce exposure to processor-related control-system downtime.
• Particularly relevant to turbine, compressor, and other rotating-equipment control systems.

One important engineering consideration is lifecycle status. Woodward currently identifies this CPU as Non-Preferred, while newer TMR CPU variants are identified as preferred.

Installation and Maintenance — 5466-1047

Before installation, compare the replacement CPU against the existing hardware revision, application software, coder version, firmware, and system configuration. Record existing settings before removing the original module.

During maintenance, use appropriate ESD protection and follow Woodward installation procedures. After replacement, confirm processor startup, system diagnostics, application execution, communication status, and TMR voting behavior. A controlled functional test should be completed before returning the turbine control system to normal operation.

For cybersecurity-sensitive installations, extra attention is required. Woodward states that this CPU does not provide the secure-password and security capabilities available on newer CPU versions.

Product Warranty — 5466-1047

Warranty coverage should be confirmed according to the supplier, condition, and purchase agreement. For critical turbine-control spares, the recommended purchasing record should identify the part number, hardware revision, serial number, test status, application compatibility, and warranty period.

For replacement planning, WOODWARD 5466-1047 remains relevant where an existing MicroNet TMR installation specifically requires this CPU configuration. Because its lifecycle status is now non-preferred, compatibility verification should be completed before procurement or substitution.
