That is a General Electric (GE) DS200TCEAG1BTF Emergency Overspeed Board.
This board is a critical component primarily used in GE’s Speedtronic Mark V Gas Turbine Control System.
🛠️ Key Information
- Primary Function: To provide emergency overspeed protection for gas turbines. It constantly monitors the turbine’s rotational speed.
- Safety Feature: If the turbine speed exceeds a safe, predetermined limit, the board will trigger an emergency shutdown sequence to prevent catastrophic failure, ensuring the safety of personnel and the equipment.
- Series: It belongs to the Mark V series of control system components.
- Functional Acronym: TCEA (often indicating the Emergency Over Speed function).
- Other Functions: In addition to overspeed, the board is often involved in processing flame detection trip signals.
- Hardware: It contains a microprocessor (like an 80196) and sockets for programmable read-only memory (PROM) modules, along with fuses and configurable jumpers.
This board is essential for the reliable and safe operation of large industrial gas turbines controlled by the Mark V system.
