Description

Product Detail: WOODWARD 5466-1002 Digital Speed Control Module

Overview

The WOODWARD 5466-1002 is a sophisticated digital control module, serving as the central processing unit for governing the speed, load, and critical parameters of industrial engines and turbines. As a core component of Woodward’s renowned 5466 series of digital engine controls, this module is engineered to deliver unparalleled precision, reliability, and flexibility in demanding applications such as power generation, marine propulsion, and gas compression. It receives input from magnetic pickups and various sensors, processes this data through advanced control algorithms, and outputs commands to actuators to maintain stable and efficient engine operation.

Key Features & Benefits

• Advanced Digital Control: Utilizes a powerful microprocessor to execute complex Proportional-Integral-Derivative (PID) control algorithms, ensuring precise speed regulation and fast response to load changes.

• Multi-Function Capability: Integrates speed governing, fuel/air ratio control, engine protection (overspeed, underspeed, low oil pressure), and synchronization/load sharing functions into a single, compact unit.

• Robust and Reliable Design: Built to withstand the extreme environmental conditions found in industrial settings, including wide temperature ranges, vibration, and electrical noise.

• Comprehensive I/O & Communication: Features a extensive array of configurable analog and digital inputs and outputs for connecting sensors, actuators, and external systems. Supports industry-standard communication protocols like Modbus, CANbus, or Woodward’s own Peer-to-Peer for seamless integration into broader control systems.

• User-Friendly Configuration: Parameters are easily set and adjusted using Woodward’s proprietary PC-based configuration tool (e.g., ToolKit software), allowing for precise tuning to match specific engine and application requirements.

• LED Status Indicators: Provides clear visual diagnostics for power, status, and fault conditions, aiding in quick troubleshooting.
