The GE IS200EDCFG1B IS200EDCFG1BAA monitors DC voltage and current in excitation circuits. This board provides critical feedback signals to the main regulator. It fits directly into GE EX2100 and Mark VIe control systems. You will rely on this unit for precise field current measurement and protection.
Technical Specifications Overview
This DC feedback board features four isolated analog input channels on one PCB. Each channel handles 0–10 V DC or 4–20 mA signals. The GE IS200EDCFG1B IS200EDCFG1BAA includes a 16-bit analog-to-digital converter for high accuracy. A built-in anti-aliasing filter removes unwanted signal noise. Consequently, you obtain clean feedback data for closed-loop regulation.

Internal Components and Energy Storage
The GE IS200EDCFG1B IS200EDCFG1BAA contains one main PCBA with 142 discrete components. Key parts include four precision instrumentation amplifiers for signal conditioning. The board also holds three electrolytic capacitors storing 880 µF of energy. This storage maintains measurement continuity during 12 ms power dips. Moreover, a dedicated microcontroller handles all analog-to-digital conversions locally. A reference voltage chip provides stable 2.5 V for the ADC.
Physical Interfaces and Connectors
You will find one front-facing 20-pin connector on this board. This connector interfaces with the EX2100 backplane for power and data. Each field wire terminates on a separate screw-type terminal block externally. Four green LEDs indicate channel activity and board health status. One red LED lights for any over-range or fault condition. Six mounting holes secure the GE IS200EDCFG1B IS200EDCFG1BAA firmly to its chassis frame.
Installation and Operational Reliability
Install this DC feedback board in a clean and grounded control cabinet. Maintain 30 mm of clearance around the board for cooling airflow. The board performs a self-calibration routine on every system power-up. Therefore, you verify measurement accuracy before generator synchronization. This unit supports continuous duty in high-vibration power plant environments.
