GE DS200TCEAG1BRE Emergency Overspeed Board

Product Positioning and Core Functions
The DS200TCEAG1BRE is a key component of the General Electric (GE) Speedtronic Mark V gas turbine control system, serving as an emergency overspeed protection device. Its core functions include:
Speed Monitoring and Protection
Real-time monitoring of the gas turbine speed is conducted. When the speed exceeds the preset safety threshold, an emergency shutdown procedure is triggered to prevent mechanical damage or explosion risks caused by overspeed.
It is applicable to rotating equipment such as gas turbines, steam turbines, and wind turbines, ensuring their safe operation under extreme conditions.
Flame Detection and Fault Isolation
Integrated flame detection circuits monitor the flame status in the combustion chamber. If flame extinction or abnormal conditions are detected, fuel supply is immediately cut off to prevent fuel accumulation from causing secondary accidents.
Quick fault isolation is achieved through the output of trip signals (such as relay contacts) and the interaction with the control system.

Application scenarios and industry value
Energy industry
Gas turbine control: In the process of oil and gas extraction, processing, and transportation, the gas turbine serving as the power source needs to strictly monitor the rotational speed and combustion status. The DS200TCEAG1BRE can prevent equipment damage or fires caused by overspeed.
Steam turbine protection: In thermal power plants, monitoring the rotational speed of the steam turbine to avoid overspeed accidents caused by sudden load changes.
Marine and offshore engineering
Propulsion system monitoring: In the gas turbine propulsion system of ships, real-time monitoring of rotational speed and flame status is carried out to ensure navigation safety.
Auxiliary power unit (APU) protection: The APU that provides power for ships needs overspeed protection to prevent the entire ship from losing power due to faults.
