Description
Product Overview
The Woodward 8440-2028 is a next-generation digital governor controller designed for mission-critical turbine and engine control in power generation, marine propulsion, and industrial applications. As part of Woodward’s 8000 series of advanced control solutions, this ruggedized module delivers ±0.05% speed regulation accuracy with adaptive control algorithms optimized for fast transient response. The 8440-2028 features a hardened stainless steel enclosure (IP67) capable of withstanding extreme environments (-40°C to +85°C, 5G vibration), making it ideal for offshore platforms, arctic installations, and other demanding applications. With dual-redundant Ethernet/IP and IEC 61850-3 communication, this controller provides seamless integration with modern distributed control systems while maintaining backward compatibility with legacy Woodward governors.

WOODWARD 8440-2028
Main Features and Advantages
Adaptive control intelligence: The Woodward 8440-2028 features NeuralTune™ technology that continuously optimizes PID parameters based on real-time system response, reducing settling time by 40% compared to conventional governors. Its LoadFeedForward™ algorithm anticipates load changes using derivative action on process variables.
Fault-tolerant architecture: Triple-redundant MPU inputs with spectral analysis detect failing sensors before critical faults occur. The module’s dual independent power supplies and watchdog processors ensure continuous operation during electrical disturbances.
Advanced diagnostics: Built-in vibration monitoring (FFT analysis up to 10kHz) and actuator performance trending enable predictive maintenance. The 8440-2028 automatically generates ISO 13374-compliant health reports with remaining useful life estimates for mechanical components.
Secure connectivity: Hardware-encrypted TLS 1.3 communication and role-based access control meet IEC 62443 cybersecurity standards. The dual Ethernet ports support PRP/HSR redundancy protocols for zero-packet-loss operation in redundant networks.
Application Field
The Woodward 8440-2028 excels in critical speed control applications:
Aeroderivative Turbines: Fast response for grid frequency stabilization
Pipeline Compression: Anti-surge control for centrifugal compressors
Marine Propulsion: Integrated control for CODLAG systems
Hydroelectric Plants: Governor control with water hammer compensation
Industrial CHP: Combined heat/power optimization algorithms
