Description
Overview
The DS200TCEAG1BSF Emergency Overspeed Protection Board is a GE‑engineered safety module used within the Mark VIe and legacy Mark V turbine control platforms. It provides independent overspeed monitoring, trip logic processing, and auxiliary safety‑related signal handling to ensure reliable turbine shutdown under abnormal operating conditions.
Functional Role
This board receives and conditions high‑priority signals such as overspeed pickup, flame detection, and emergency trip commands. It executes hardware‑based protection logic to guarantee deterministic response times, independent of the main control processor. The DS200TCEAG1BSF also interfaces with system communication modules and contributes to the overall protection chain of gas and steam turbine installations.
Environmental and Electrical Characteristics
Engineered for harsh industrial environments, the module supports extended operating conditions and robust electrical isolation. Its design ensures stable performance in turbine enclosures where temperature, vibration, and electrical noise are common.
Key electrical and environmental parameters include:
-
Operating temperature range: −40°C to +70°C
-
Relative humidity tolerance: 5%–95% non‑condensing
-
Input power: 24 VDC ±10%
-
Power consumption: approximately 8 W
-
Isolation rating: 1500 VAC for signal protection
Mechanical Details
The board is compact and lightweight, simplifying installation in existing Mark VIe or Mark V racks. Its construction follows GE’s industrial‑grade PCB standards for long‑term reliability.

FAQ
Q: Does the board operate independently of the main controller? A: Yes. Overspeed and trip logic are executed in hardware to ensure deterministic protection.
Q: Can this module replace earlier overspeed boards in Mark V systems? A: It is primarily intended for Mark VIe but may be used in Mark V systems when system compatibility is confirmed.
Q: What isolation level does the board provide? A: It offers 1500 VAC isolation for enhanced signal integrity and safety.
