IS200EDCFG1ADC – Exciter DC Feedback Board

The IS200EDCFG1ADC is a high-performance Exciter DC Feedback Board developed by General Electric for use within the GE EX2100 excitation control system. This board plays a vital role in monitoring and controlling the DC output of the exciter, providing accurate feedback on both the field current and field voltage. This feedback is essential for maintaining the correct excitation levels of the generator to ensure stable and efficient power generation.

The IS200EDCFG1ADC is engineered to receive signals directly from the field circuit, including analog inputs for both voltage and current. These signals are conditioned and processed by the board before being transmitted to the controller. By providing real-time feedback, the board enables closed-loop regulation, improving the precision of excitation control and enhancing generator performance under varying load conditions.

This board features galvanic isolation between its input and output sections to ensure signal integrity and electrical protection. It is specifically designed for integration into the EX2100 system’s feedback loop and supports dynamic performance during both steady-state operation and fault conditions. The IS200EDCFG1ADC also supports redundancy configurations where required, increasing overall system reliability.

Its robust construction ensures reliable performance in demanding industrial  environments such as power plants and industrial facilities. It can withstand electrical noise, temperature variations, and mechanical vibrations commonly found in high-voltage settings. The modular nature of the board allows for fast field replacement and ease of maintenance, reducing downtime and ensuring high availability of the excitation system.

Used in conjunction with other EX2100 components, the IS200EDCFG1ADC supports digital monitoring and system diagnostics, which help identify operational anomalies and reduce time for troubleshooting. This makes it an indispensable element in modern excitation systems that demand fast response, high reliability, and precise control.
