The GE IS210TREAS1A is a Aero Trip Terminal Board with Daughter Board for the Mark VIe series of GE’s Speedtronic Gas Turbine Control Systems. It is a critical component of the turbine’s protection system, providing a physical interface for initiating a trip in an aero-derivative gas turbine. The “AERO” in the name indicates its specific application, and “DBRD” stands for “Daughter Board,” which is an additional circuit board that plugs into the main board to provide extra functionality.
Key Features and Functionality
The IS210TREAS1A is vital for the safety of an aero-derivative turbine. Its main functions include:
- Aero-Derivative Turbine Specialization: This board is specifically designed for the unique trip requirements of aero-derivative turbines, which are adapted from jet engines and often have different trip logic and sensors than large industrial gas turbines.
- Trip Relay Interface: The board provides the physical connection points for signals that initiate a turbine trip. These signals are typically from safety-critical devices like overspeed detectors or emergency stop buttons.
- Daughter Board: The inclusion of a daughter board adds specific functionality to the main board. This could be for signal conditioning, additional processing, or implementing specific trip logic tailored to the turbine model.
- Fail-Safe Design: The board is designed to be fail-safe, meaning that a loss of power to the relays on the board will cause the trip circuit to activate. This ensures that the system will shut down in a controlled manner if a power failure occurs.
- Safety-Critical Application: The board is used in safety-critical applications where a reliable and fast shutdown is required to protect the turbine from catastrophic damage.
