I. Product Overview

WOODWARD 5450-106 is the core central processor module of the MicroNet / NetCon 5000 control system. It is specifically designed for high-speed and high-precision control of steam turbines, gas turbines, and engines, responsible for executing complex control algorithms, logical operations, data processing, and system management. It is the "brain" of the entire control system. 

II. Core Functional Characteristics

High-performance processing: 32-bit industrial-grade processor, capable of real-time execution of complex algorithms such as speed control, load control, and sequence control.

Full-function control: Integrated speed regulation, synchronous control, load distribution, and overspeed protection.

Dual serial port communication: Independent RS-232 and RS-422 interfaces, supporting Modbus protocol, and supporting remote programming and monitoring.

PWM drive output: Low-current PWM signal output, precisely driving electro-hydraulic actuators (I/H converter).

Adaptive sensing: Built-in adaptive speed sensing algorithm, compatible with magnetic-electric (MPU) and eddy current sensors.

Data recording: Built-in non-volatile memory, records key operating parameters, events, and fault logs.

Hot-swappable design: Supports online maintenance, allowing plug-and-play without affecting system operation.

Industrial-grade reliability: Wide temperature range, shock resistance, full isolation design, and Class I Div II explosion-proof certification.
