GE IS200WREAH1A AERO TRIP TB DBRD

الوصف

The GE IS200WREAH1A is a Aero Trip Terminal Board Daughter Board for the Mark VI series of GE’s Speedtronic Gas Turbine Control Systems. It is a specialized, optional board that works with the main I/O cards to provide trip and overspeed protection for aeroderivative turbines.

Key Features and Functionality

The IS200WREAH1A is crucial for the safety and protection of aeroderivative turbines. Here’s a breakdown of its primary functions:

• Overspeed Protection: Aeroderivative turbines have very high operating speeds, making overspeed protection a critical safety function. The WREA board is designed to interface with high-speed sensors (like magnetic pickups) to monitor turbine speed with high accuracy. If the speed exceeds a predefined threshold, the board can initiate a trip (a rapid shutdown) of the turbine to prevent catastrophic failure.
• Trip Logic: The board provides redundant trip logic circuits. This means that a single point of failure won’t compromise the safety of the system. The board can be configured for different trip settings and can handle multiple trip inputs to ensure robust protection.
• Daughter Board Design: The IS200WREAH1A is a daughter board that plugs into a compatible main VME card, such as a turbine card (VTUR). This modular design allows for flexible system configuration and simplifies maintenance, as the board can be replaced independently of the main card.
• Redundancy: The board is designed to support the redundant architecture of the Mark VI system. In a triple modular redundant (TMR) system, multiple WREA boards can be used to provide layers of protection, ensuring the system remains operational even if one of the boards fails.
