Features:
- Deterministic Real‑Time Logic Execution
- Native NetCon Chassis Integration
- Extended Environmental Survivability
The WOODWARD 5466-352 excludes Large Logic memory by design, forcing the CPU to execute only core turbine control algorithms without scanning non‑critical blocks. This ensures sub‑millisecond jitter for overspeed detection and fuel valve modulation—essential for API 670 compliance.
The WOODWARD 5466-352 communicates directly over the high‑speed NetCon backplane, achieving deterministic I/O scans with local analog, digital, and speed sensor modules. There is no need for external couplers or protocol converters, reducing latency and point of failure.
Rated for -40°C to +70°C operation and 5 g vibration, the WOODWARD 5466-352 mounts directly in turbine control panels located outdoors or in non‑conditioned enclosures. Conformal coating on the PCB protects against humidity and airborne contaminants common in compressor stations and offshore platforms.
The 5466-352 Woodward NetCon CPU 044 Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Gas Turbine Generator Control:The WOODWARD 5466-352 executes fuel scheduling, inlet guide vane positioning, and generator load sharing in both single‑shaft and two‑shaft turbines, replacing legacy CPU 040 boards without rewiring.
- Steam Turbine Overspeed Protection:With deterministic task execution, this CPU 044 module manages two‑out‑of‑three (2oo3) speed sensor voting and fast valve stroking, meeting API 611/612 requirements for mechanical drive steam turbines.
- Reciprocating Compressor Sequencing:The WOODWARD 5466-352 controls start/stop sequences, unloader staging, and knock‑limit feedback on large bore gas compressors used in pipeline transmission or LNG terminals.
- Legacy NetCon System Retrofit:When a 5466-334 or 5466-351 fails, the 5466-352 provides a form‑fit‑function replacement, extending the life of existing Woodward cabinets without a full control system upgrade.
- Capabilities Real‑Time Diagnostic Variables:The WOODWARD 5466-352 exposes >50 internal diagnostic parameters (execution time, stack usage, communication error counters) via Modbus, enabling predictive maintenance in SCADA.
- Hardware Watchdog with Fail‑Safe Reaction:An independent timer within the CPU 044 forces all I/O modules to predefined safe states (e.g., close fuel valves) if the main control task does not reset the watchdog every 250 ms.
- Non‑Intrusive Online Monitoring:Using NetCon Tools connected to the debug port, engineers can view live variable trends, force outputs, and capture execution traces without stopping the turbine—critical for troubleshooting during production.
- Event Sequence Logging:The module stores up to 512 time‑stamped events (power‑on, mode changes, watchdog resets, configuration downloads) in non‑volatile memory, retrievable via serial connection for forensic analysis.
- Wide Ambient Temperature Range:Rated for -40°C to +70°C continuous operation, the WOODWARD 5466-352 functions reliably in unheated turbine enclosures during Arctic winters or inside desert solar‑heated control rooms without supplemental cooling.
- High Vibration & Shock Immunity:Withstanding 5 g vibration (10‑500 Hz) and 30 g shocks, this CPU mounts directly on the backplane of a turbine skid subject to gas pulsation or generator magnetic forces, unlike commercial PLCs that require isolation mounts.
- Humidity & Contaminant Protection:Factory conformal coating protects the:WOODWARD 5466-352 from 95% relative humidity and salt‑laden air (e.g., offshore platforms) as well as light dust typical of compressor stations. Not rated for immersion or high‑pressure washing.
- ESD Hardened Design (With Proper Handling):Although internally containing Class‑1 ESD‑sensitive components, the WOODWARD 5466-352 passes 8 kV contact discharge per IEC 61000-4-2 when installed in a properly grounded chassis. Always use ESD straps during maintenance.
