Frequently Asked Questions
What is the primary function of this board?
The IS200EDEXG1B serves as a De-Excitation Bridge and Protection Board, controlling and protecting generator fields during shutdown procedures in EX2100 systems.
What happens if the EXTB board fails?
This board can autonomously initiate de-excitation procedures if the primary EXTB control fails, providing critical backup protection for the generator field.
How does the overvoltage protection work?
When the anode-to-gate voltage exceeds the break-over voltage of the diode string, the SCR fires automatically to protect the system from overvoltage conditions.
What documentation covers this board?
Complete technical specifications and installation procedures are documented in the GEH-6632 manual for the EX2100 Innovation Series.
What power supply is required?
The board operates on 24 VDC power, typically supplied through the EXTB board interface in the excitation control system.
