I. Product Overview

WOODWARD 5441-697 is the core central processing unit module of the MicroNet and NetCon 5000 control system. As the "brain" of the system, it is responsible for executing complex control algorithms, logical operations, data processing, and system management. This module integrates a high-performance processor, large-capacity memory, and a rich set of communication interfaces, specifically designed for high-precision and high-reliability control of high-speed rotating machinery such as turbines, generators, and compressors. This model has been discontinued and the market is mainly composed of refurbished / spare parts.

II. Core Functional Characteristics

High-performance processing core: Equipped with a 32-bit industrial-grade processor, with strong floating-point computing capabilities, ensuring millisecond-level response of control loops.

Dual-port memory architecture: Supports high-speed data sharing with I/O modules and other processors, enabling multi-processor collaborative work.

Multiple protocol communication: Built-in Ethernet, RS-232, RS-422, Modbus, Profibus DP interfaces, seamlessly connecting DCS, PLC, and upper computer systems.

Real-time operating system: Runs a dedicated real-time operating system (RTOS), ensuring deterministic execution of control tasks without delay jitter.

Redundant design: Supports 1:1 hot redundancy configuration, with no disturbance switching (< 5ms) to ensure continuous operation of critical equipment.

Program and data storage: Integrated with large-capacity non-volatile memory (Flash/RAM), saving control programs, parameters, and historical data.

Self-diagnostic function: Comprehensive hardware self-checking, program monitoring, fault recording, and alarms, supporting remote diagnosis.

Industrial-grade reinforcement: Wide temperature, shock-resistant, dustproof design, passing CE, UL, Class I Div II explosion-proof certifications.
