Exciter De-Excitation Board GE IS200EDEXG1BBB for Generator Protection

Description

The GE IS200EDEXG1BBB Exciter De-Excitation Control Board is a critical component within GE’s Mark VI turbine control architecture. Its primary function is to rapidly reduce and dissipate excitation current from synchronous generators during shutdowns, trips, or fault conditions. This controlled de-excitation prevents overspeed and protects both the generator and connected systems from damage. Moreover, the EDEX board integrates seamlessly into excitation control cabinets and works in tandem with other Mark VI modules. In addition to its core protection role, it supports diagnostic monitoring and fault isolation, helping operators maintain system reliability. Engineers value its rugged design, fast response time, and compatibility with GE’s EX2100 excitation systems. Therefore, the IS200EDEXG1BBB is widely deployed in gas turbine generator systems where precise control and rapid fault response are essential.
