GE IS200EAUXH1AAA Exciter Auxiliary Interface Board

Product Description

IS200EAUXH1AAA is an exciter auxiliary interface board (EAUX) for GE EX2100E generator excitation control system under Mark VIe platform. It is a conformal coated printed circuit board designed for TMR high-reliability control architecture, communicating with main controller via HSSL high-speed serial link. This board handles auxiliary I/O and flash firing signal output for thyristor excitation bridges.

Product Functions

• Provide auxiliary signal termination and conditioning for EX2100E excitation regulator
• Generate flash output up to 41 VDC for thyristor excitation firing control
• Transfer digital and analog auxiliary signals between field devices and main processor
• Built-in power and fault LED indicators for on-site diagnosis
• Support TMR redundant operation to improve excitation system stability
• Isolate field wiring to protect internal turbine control circuits from interference

Applications

• Generator excitation control for gas turbines and steam turbines
• EX2100E excitation rack spare replacement in power plants
• Utility power station and heavy industrial generator protection & control
• Onshore and offshore power generation turbine control systems
• Retrofit and maintenance of legacy Mark VIe Speedtronic systems
