Products Description
GE IS200EXHSG3AEC Mark VI Exciter HS Relay Driver Board
GE IS200EXHSG3AEC is an Exciter HS relay driver board designed for GE Mark VI turbine control system and EX2100 static excitation system. It integrates solid-state relay drivers and multiple relay circuits to control high-speed contactors for generator excitation loop protection and switching operations.

This board communicates with the main controller via VME backplane bus and adopts conduction cooling design suitable for power plant cabinet environment. It serves as critical spare parts for gas turbine, steam turbine and generator excitation system maintenance and renovation projects.
