GE IS200EXCSG1A Exciter Conduction Sensor Board

Product Introduction

The GE IS200EXCSG1A Exciter Conduction Sensor Board is an advanced monitoring and feedback circuit board developed for GE Mark VI and related excitation systems.
It serves as the critical interface between the exciter power stage and the control logic, sensing conduction currents and providing real-time data to the system’s regulator.
By continuously measuring and transmitting conduction signals, the IS200EXCSG1A enables precise generator field control, ensuring stable voltage, optimal excitation, and enhanced system protection.
Its rugged PCB design, robust connectors, and high-accuracy sensor network allow it to operate reliably in demanding industrial and utility environments such as power generation stations, marine propulsion systems, and heavy industrial drives.
