Description
1. At-A-Glance Executive Brief
- Model: 5466-5025 (MicroNet Pentium CPU Module)
- Brand: Woodward
- Part Type: Central Processing Unit (CPU) / Digital Controller Module
- Lifecycle Status: Mature / Legacy Support Line
- Processor Speed: 233 MHz Pentium processor architecture
- Net Weight: ~1.2 kg
- Core Application: Core processing, deterministic control loop execution, system timing, and communication management for legacy Woodward MicroNet turbine and engine control systems
2. Technical Introduction
A processor fault, clock failure, or sudden memory corruption on a legacy Woodward MicroNet control rack can cause unexpected turbine trips, halt control program execution, and result in costly facility downtime.
The Woodward 5466-5025 is a reliable MicroNet Pentium CPU module featuring a 233 MHz processor. It serves as the primary computational engine for legacy MicroNet control chassis, responsible for handling control algorithms, system diagnostics, and card-to-card backplane communications. Deploying a verified original replacement CPU module restores system execution logic and operational availability without requiring application rewrites.
Engineer’s Takeaway: Procuring an authentic Woodward 5466-5025 ensures exact backplane slot dimensions, slot-pin compatibility, and execution timing compliance across legacy MicroNet hardware architectures, eliminating configuration friction during emergency repairs.

4. Field Engineer’s Tech Notes
- Battery Backup and NVRAM Status: Check the status of the onboard lithium backup battery or SRAM module before installation. A depleted battery can cause the loss of retentive memory and application files upon power interruption.
- Firmware and Software Version Alignment: Ensure that the control application file version matches the firmware version loaded on the replacement 5466-5025 unit. Mismatched software revisions will trigger processor faults or communication blocks with adjacent I/O cards.
5. Adaptive QA & Testing Protocol
Every unit undergoes rigorous bench validation prior to dispatch. For the Woodward 5466-5025, our technicians mount the module in a dedicated MicroNet test rack simulator to verify processor initialization, check onboard memory integrity, test communication port response, and validate backplane bus communication stability. Functional test reports or pre-shipment video verification can be provided upon request.
6. Buyer’s FAQ
- Are these CPU modules supplied as New Surplus or refurbished?
We stock both factory-sealed New Surplus (NSFP) and fully bench-tested, static-safe operational units. Condition status is explicitly marked on every quote.
- What warranty coverage comes with this part?
All replacement Woodward control modules are backed by a standard 12-month operational warranty from the date of invoice.
- How fast can this CPU module ship to minimize plant downtime?
In-stock items ship same-day via priority air courier services to global destinations, mitigating critical path delays during emergency turbine outages.
- Can our existing application program be downloaded directly to this replacement CPU?
Yes, the application program and configuration files can be transferred to the replacement 5466-5025 module via the service port using standard Woodward engineering tools.
