General Electric DS200TCEAG1BSF Emergency Over Speed Board

The DS200TCEAG1BSF is an Emergency Overspeed Board designed for use in Speedtronic Mark V turbine control systems. This critical board monitors overspeed and flame detection conditions, triggering an emergency shutdown when necessary to protect the turbine.

Key Features

• Function: Monitors overspeed and flame detection conditions to ensure safe turbine operation.
• Components: Includes a microprocessor, PROM modules, fuses, jumpers, and bayonet connectors.
• Connection: Uses bayonet connectors to link system components for secure connections and easy installation.

Installation & Maintenance

• Bayonet Connectors: Ensure proper alignment when connecting or disconnecting to maintain a secure connection.
• Fuses and Jumpers: These components are easily accessible for replacement and configuration to meet site-specific needs.

Application Areas
The GE DS200TCEAG1BSF​ is exclusively deployed in power generation facilities utilizing the GE Mark VI turbine control system. Its primary application is in simple and combined-cycle power plants, where it is used to interface temperature sensors from GE Frame 5, 6, 7, and 9F gas turbines and steam turbines. It terminates wiring from bearing temperature RTDs, turbine exhaust thermocouples, and blade path temperatures, providing the critical data needed for the control system to monitor turbine health and prevent damage from overheating.
Furthermore, the module is used to interface with temperature sensors in the auxiliary systems, such as lube oil cooler temperatures and generator bearing temperatures. In all these applications, the reliable and accurate temperature data provided through the DS200TCEAG1BSF​ is essential for the turbine’s protection system (alarms and trips), performance calculations, and efficient operation. A failure in this termination system could lead to inaccurate temperature readings, potentially resulting in a nuisance trip or, in a worst-case scenario, a failure to detect an overtemperature condition.
