Woodward 5466-114 Replacement CPU for Gas & Steam Turbines

Product Overview

The Woodward 5466-114 functions as the primary MicroNet 60 CPU module, serving as the computational heart for mission-critical turbine control platforms. This industrial-grade processor executes high-speed PID loops, complex safety logic, and turbine sequencing in real-time. We offer this unit as 100% Brand New stock, providing a vital lifecycle extension for existing MicroNet systems. It manages critical parameters for gas, steam, and hydro turbines, ensuring grid stability and mechanical protection in the most demanding power generation environments.

Technical Specifications

The 5466-114 utilizes a fanless, passive cooling architecture to maximize Mean Time Between Failures (MTBF) in high-vibration turbine decks.

Engineering Advantages

• High-Fidelity Real-Time Execution: The 5466-114 processes complex turbine algorithms with deterministic timing. This ensures that safety logic and valve demands execute without jitter, preventing turbine overspeed or flameout conditions.

• Flexible Redundancy Architectures: This module supports hot-swappable Simplex, Redundant, and Triple Modular Redundant (TMR) configurations. In TMR mode, the system utilizes 2-out-of-3 voting logic to provide zero-fail operation for critical utility assets.

• Thermal and Electrical Ruggedization: Woodward engineers the MicroNet 60 series to thrive where standard PLCs fail. It withstands heavy Electromagnetic Interference (EMI) and temperature swings from -40°C to +70°C, typical of turbine enclosures.

• Seamless Legacy Integration: The 5466-114 allows plants to maintain legacy NetCon or early MicroNet chassis while upgrading processing power. This significantly reduces the "rip-and-replace" costs associated with total system migrations.

• Maintenance-Free Hardware: The passive cooling design eliminates mechanical fans—the most common failure point in industrial CPUs—ensuring long-term reliability in dusty or remote industrial environments.

FAQs

Q: The 5466-114 is listed as obsolete; can I still use it for repairs?

A: Yes. While Woodward replaced this series with the CPU5200 (5466-1245), the 5466-114 remains the direct replacement for existing MicroNet 60 racks. Using a brand-new 5466-114 avoids the need for immediate, costly chassis upgrades or extensive software recompilation required by newer CPU generations.

Q: Does this module support TMR (Triple Modular Redundancy)?

A: Absolutely. When you install three 5466-114 modules in a TMR-configured MicroNet chassis, they perform hardware-level voting. If one processor fails or disagrees, the other two maintain uninterrupted control of the turbine.

Q: What is the primary difference between the 5466-114 and the newer 5466-1245?

A: The 5466-1245 (CPU5200) offers higher processing speeds and enhanced cybersecurity features. However, for maintaining older systems without changing the application software or communication infrastructure, the 5466-114 provides the exact hardware-to-software compatibility required for "plug-and-play" replacement.

Q: Does this CPU require an external cooling fan?

A: No. The hardware utilizes high-efficiency heatsinks for passive cooling. This design prevents internal dust accumulation and extends the electronic component life by operating without moving parts.
