Main Features and Advantages ：Woodward 8237-1600
Triple Modular Redundancy (TMR): The Woodward 8237-1600 employs three independent control modules with 2-out-of-3 voting logic, ensuring high fault tolerance and continuous operation even in the event of a single module failure. This architecture minimizes false trips and enhances system integrity.
Rapid Fault Detection: Using advanced algorithms, the module monitors turbine speed derivatives to detect over-acceleration events, providing proactive protection against sudden speed surges. Its trip response time of less than 100 ms ensures critical shutdown commands are executed promptly.
Online Maintenance Capability: The plug-and-play design allows users to replace individual modules while the turbine remains operational, reducing downtime and maintenance costs. Inter-module learning functionality ensures seamless synchronization after component replacement.
Environmental Resilience: The conformal coating on the Woodward 8237-1600 protects against sulfur-based gases (H2S, SO2) and meets IEC 721-3-3 1994 environmental class 3C2, making it suitable for corrosive environments common in oil refineries and chemical plants.
Comprehensive Diagnostics: The system provides real-time speed readings (4–20 mA), fault logs with timestamps, and automatic test routines to verify MPU functionality. These features simplify troubleshooting and support predictive maintenance strategies.
