Description
Product Overview
The Woodward 8440-1713/D is a high-precision digital governor controller designed for critical speed regulation in industrial gas turbines, steam turbines, and large reciprocating engines. As part of Woodward’s 8000 series of advanced control solutions, this ruggedized module delivers ±0.025% speed regulation accuracy with adaptive neural network control algorithms, making it ideal for applications requiring ultra-stable operation. The 8440-1713/D features a military-grade stainless steel enclosure (IP68) capable of withstanding extreme environments (-40°C to +90°C, 10G vibration, 50G shock), including offshore platforms and arctic installations. With quad-redundant processing cores and IEC 62443-4-2 cybersecurity certification, this controller provides deterministic <20ms response times while protecting against modern cyber threats. The /D suffix denotes enhanced diagnostics with predictive maintenance capabilities for turbine health monitoring.

WOODWARD 8440-1713/D
Main Features and Advantages
AI-driven control optimization: The Woodward 8440-1713/D implements deep learning-based control algorithms that continuously adapt to system dynamics, achieving 60% faster settling times than conventional PID controllers. Its Digital Twin integration allows real-time performance simulation and optimization.
Military-grade reliability: Featuring quad-redundant FPGAs with nanosecond-level synchronization, the controller meets MIL-STD-810H specifications for shock/vibration. The hermetically sealed enclosure survives 300m water immersion and high-pressure washdowns.
Predictive health analytics: Embedded vibration spectrum analysis (0-50kHz) and lubrication monitoring predict mechanical issues months in advance. The /D version adds ISO 13374-3 compliant asset health reporting with remaining useful life calculations.
Cybersecurity hardened: Implements IEC 62443-4-2 SL3 requirements including HSM-protected secure boot, runtime attestation, and quantum-resistant cryptography. The physical air-gap switch maintains safety during cyber maintenance.
