Woodward 8440-2052 Industrial Speed Control Module

Product Details

The Woodward 8440-2052 is an industrial speed control module, specifically a part of the ProTech-GII series, designed as an overspeed protection device for turbines and other rotating machinery. Here are its key features and specifications:

Key Features:

1. Overspeed Protection:
   • The 8440-2052 is equipped to monitor the speed of turbines (steam, gas, hydro) and can initiate a shutdown in the event of unsafe acceleration, thereby preventing potential damage.
2. Triple Modular Redundancy (TMR) Architecture:
   • It utilizes three independent relays and a two-out-of-three voting architecture to ensure high reliability and safety. This redundancy allows the system to continue functioning even if one module fails.
3. MPU and Acceleration Detection:
   • The module incorporates MPU (Magnetic Pickup Unit) detection to monitor turbine speed and acceleration. It can be configured to detect and respond to acceleration events to protect the turbine.
4. Resistant to Sulfur Contamination:
   • The 8440-2052 is coated with a special conformal coating that provides long-term protection against H2S and SO2 gases, making it suitable for use in harsh environments (Class 3C2).
5. Online Repair Capability:
   • The module supports online repair, meaning that one module can be replaced while the entire system remains in operation. This feature minimizes downtime and enhances system availability.
6. Modbus Communication:
   • It includes Modbus communication capabilities, facilitating integration with distributed control systems (DCS) and other industrial automation platforms.
7. Easy Integration:
   • The module is designed for easy integration into turbines of any size, whether they are steam, gas, or hydro-powered.
8. Compliance with Standards:
   • The ProTech-GII series, including the 8237-1597, is certified to IEC 61508 SIL-3 and complies with API 670 and API 612 standards, ensuring its suitability for safety-critical applications.

Applications:

• Power Generation: Used in steam turbines, gas turbines, and hydro turbines to provide overspeed protection.
• Industrial Machinery: Suitable for various rotating machinery where overspeed protection is critical.
• Oil and Gas: Can be applied in compressors, pumps, and other equipment to ensure safe operation.
