Description
Product Overview
The Woodward 8440-2052 H is a high-performance digital governor controller designed for heavy-duty industrial applications in power generation, marine propulsion, and large mechanical drive systems. 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 under extreme conditions. The 8440-2052 H features a military-grade stainless steel enclosure (IP68) capable of withstanding the most demanding environments (-40°C to +90°C, 10G vibration, 50G shock), including offshore platforms, arctic installations, and high-vibration industrial sites. 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 “H” suffix denotes enhanced hardware specifications for heavy industrial duty cycles and extended service life.

Woodward 8440-2052 H
Main Features and Advantages
Industrial-strength construction: The Woodward 8440-2052 H features thick-wall stainless steel housing with vibration-isolated component mounting, specifically engineered for 250,000+ hour service life in heavy vibration environments. Its hermetically sealed connectors prevent moisture ingress in offshore and coastal installations.
AI-optimized control: Implements deep learning-based adaptive control that continuously improves performance, achieving 60% faster settling times than conventional adaptive controllers. The Digital Twin LiveLink™ provides real-time hardware-in-the-loop simulation for performance optimization.
Predictive maintenance 3.0: Advanced multi-physics modeling combines vibration (0-50kHz), lubrication, and thermal data to predict failures with 95% confidence 6+ months in advance. The system generates AS9100-compliant prognostic health reports with remaining useful life calculations.
Military-grade cybersecurity: Implements NIST-approved post-quantum cryptography and physically unclonable functions (PUFs) for chip-level security. The optical isolation firewall maintains protection even during cyber attacks, meeting IEC 62443-4-2 SL4 requirements.
