Product Description
Woodward 5541-693 MicroNet TMR Digital Control System
Product Overview
- The Woodward 5541-693 is a MicroNet Triple Modular Redundant (TMR) Digital Control System designed for high-reliability control of industrial applications such as gas and steam turbines, compressors, and power generation systems. This system integrates a central processing unit, I/O modules, and communication interfaces to execute complex control algorithms, manage input/output signals, and ensure fault-tolerant operation through triplicated processing with 2-out-of-3 voting. It is commonly used in industries like power generation, oil and gas, aerospace, and marine, recognized for its robust performance, scalability, and seamless integration with Woodward’s MicroNet platform. The 5541-693 is a complete control system, distinct from individual modules like the 5466-series, offering a comprehensive solution for critical applications.
