GE IS200EDCFG1B Exciter DC Feedback Board

Product Introduction

The GE IS200EDCFG1B is an Exciter DC Feedback Board developed by General Electric as part of the Mark VIe Series of control systems. This board plays a vital role in exciter control systems by providing accurate DC feedback signals to the control module. It is typically used in conjunction with GE’s EX2100 Excitation Control Systems and integrates seamlessly with turbine generator systems to enhance monitoring and regulation of excitation voltage and current.

The IS200EDCFG1B collects and processes analog voltage and current feedback from the generator field circuit. These signals are essential for maintaining stable generator output and ensuring system safety. Designed with high-reliability components, the board includes isolation features, precision resistors, and filtering circuitry to deliver clean, stable feedback data.

This board is commonly found in industrial power generation facilities, especially in high-demand environments such as thermal, nuclear, and hydroelectric power stations where reliable excitation control is critical.
