Description

Product Overview

The WOODWARD 5466-352 is a NetCon CPU-040 module used as a central processing component in legacy Woodward NetCon and MicroNet control systems. Woodward’s own product documentation identifies this part number as a NetCon CPU_040 module without LL memory, distinguishing it from the related CPU-040 version with LL memory.

The module performs core control-system processing and communication functions, making it an important component in installed turbine and engine control platforms. Available technical references identify a 68030 processor architecture, dual-ported RAM for VME-bus communication, and interfaces supporting network communication processors. For maintenance inventories, the main concern is configuration matching: CPU type, memory configuration, chassis generation, application software, and system architecture should all be checked before replacement.

Technical Specifications — 5466-352

Woodward’s parts listing specifically describes 5466-352 as “NetCon CPU_040, LL memory not included,” while the related 5466-351 is the LL-memory version.

Key Features and Benefits — 5466-352

• Central processing capability for legacy NetCon/MicroNet control platforms.
• 68030-based processing architecture.
• Dual-ported RAM provides the communication path to the VME bus.
• Supports communication with network processors within the control architecture.
• Service-panel access is available for applicable standalone MicroNet configurations.
• Watchdog logic can place the system into an IOLOCK state when a CPU failure is detected, de-energizing affected outputs and signals.
• Useful as an installed-base maintenance spare where the original CPU architecture must remain in service.

Related Models

5466-351: NetCon CPU-040 module with LL memory. It belongs to the same CPU family but has a different memory configuration, so it should not be assumed to be an interchangeable replacement.

5466-350: NetCon CPU-060 module, representing a different CPU configuration within the same legacy NetCon product family.

5466-353: NetCon main chassis transceiver used for chassis-level communication within the legacy control architecture.

5466-354: NetCon remote chassis transceiver designed for communication with remote chassis equipment.

Installation and Maintenance — 5466-352

Before replacing the module, document the existing CPU revision, chassis position, application configuration, memory configuration, and communication connections. Power isolation should follow the plant’s approved turbine-control maintenance procedure.

Inspect the card edge connector, PCB, mounting hardware, and front-panel indicators before installation. After replacement, verify CPU initialization, application loading, chassis communication, I/O status, and any active diagnostic indications.

Part-number matching alone is not sufficient for a legacy controller. The 5466-352 belongs to an older NetCon/MicroNet generation, and migration to newer Woodward platforms may require changes to the CPU, chassis, power supply, I/O hardware, and application software.

Product Warranty — 5466-352

Warranty coverage depends on the supplier, product condition, and purchase agreement. For a critical control-system spare, procurement records should include serial-number traceability, hardware revision, inspection or functional-test documentation, and clearly stated warranty terms.

The WOODWARD 5466-352 is best maintained as an exact-match legacy CPU spare when the installed NetCon/MicroNet architecture remains operational. Personally, I would verify the CPU memory configuration first; confusing the LL-memory and non-LL-memory variants is an easy mistake during emergency replacement.
