WOODWARD 5466-409 – MicroNet Pentium CPU Module
Product Overview
The WOODWARD 5466-409 is a MicroNet Pentium CPU module used in Woodward MicroNet digital control systems. Woodward documentation identifies it as a MicroNet Pentium CPU with a 233 MHz processor, 64 MB RAM, and Windows NT 4.0 operating software. The module is designed for simplex MicroNet configurations and is installed in an expansion chassis with the appropriate transceiver architecture. It provides the processing platform required to execute the control application and communicate with external engineering or service equipment. The module includes Ethernet and serial communication capability and is associated with Woodward MicroNet turbine and industrial control applications. Woodward lists this part as inactive, making accurate identification and tested replacement stock important for legacy system maintenance.

WOODWARD 5466-409
Key Features and Benefits — 5466-409
- Pentium-based processing platform for legacy MicroNet controls.
- 233 MHz CPU with 64 MB RAM.
- Ethernet connectivity for application and service operations.
- Dual RS-232 serial communication capability.
- Designed for simplex MicroNet architecture.
- Suitable for maintaining installed turbine-control systems without immediately replacing the complete control platform.
Personally, I would verify the simplex architecture, software environment, and expansion-chassis configuration before purchasing a replacement. This is an older CPU platform, and compatibility depends on the installed application and MicroNet hardware configuration, not just the processor board.

Installation and Maintenance — 5466-409
Before replacement, record the installed application software, operating-system revision, controller configuration, communication settings, and chassis position. Verify the transceiver arrangement because the 5466-409 is intended for simplex operation in the MicroNet expansion architecture.
During maintenance, inspect the board connector, Ethernet and RS-232 interfaces, cooling conditions, and memory/storage components. After installation, confirm that the control application loads correctly and that communication with the main MicroNet controller and service workstation is restored.
Product Warranty — 5466-409
Warranty coverage depends on supplier condition and sales terms. Confirm whether the unit is new old stock, refurbished, repaired, or previously installed, and request serial-number traceability, functional-test records, software information, and the applicable warranty period.
The WOODWARD 5466-409 is a legacy MicroNet CPU, so tested replacement stock with verified application compatibility is generally more useful than a visually similar CPU from another MicroNet generation.
