Description
The GE IS200EDCFG1AED is a specialized DC Feedback board designed for use within the GE Innovation Series and EX2100 Excitation Control systems. Its primary function is to provide accurate voltage and current feedback from the exciter’s DC output back to the control processors. This board is critical for maintaining the closed-loop regulation of the generator field, ensuring that the excitation levels are precisely managed to maintain grid stability and voltage regulation.
- System Series: EX2100 / Innovation Series
- Feedback Channels: High-precision DC voltage and DC current sensing
- Signal Isolation: Optical and magnetic isolation to protect low-voltage control circuits from high-power DC buses
- Accuracy: High-linearity processing for exact field measurement
- Interface: Connects to the main control rack via high-density ribbon cables or D-type connectors
- Revision: AED (indicates hardware version with specific component optimizations)
- Operating Voltage: Typically 24V DC auxiliary power with high-voltage monitoring capabilities

Application Fields
This feedback board is a vital component in power generation infrastructure:
- Generator Excitation Systems: Providing the real-time data needed for the Automatic Voltage Regulator (AVR) to manage generator output.
- Gas and Steam Turbine Control: Part of the integrated control suite for large-scale turbine-generator sets.
- Synchronous Motor Control: Managing the excitation fields for large industrial synchronous motors in pumping or compressor stations.
- Utility Power Substations: Monitoring DC bus health in high-capacity power conversion systems.
Product Instructions
- Safety Protocol: High-voltage DC is present in excitation cabinets. Ensure the unit is de-energized, the field breaker is open, and all capacitors are discharged before service.
- ESD Management: Handle the IS200EDCFG1AED board in an ESD-protected area. Use a grounded wrist strap to prevent damage to the high-impedance sensing circuits.
- Physical Installation: Slide the board into its designated slot in the control rack. Ensure the backplane connectors are fully engaged and any securing screws are tightened.
- Cabling: Attach the feedback leads from the DC shunts and voltage dividers. Verify that all connections are secure to prevent intermittent feedback signals which can cause excitation trips.
- Commissioning: Once installed, use the system’s diagnostic software (e.g., ToolboxST) to verify that the DC feedback readings match the actual values measured at the power terminals with a calibrated multimeter.
Q&A – Common Questions
Q1: What does the “AED” suffix represent on this board? A1: The “AED” suffix indicates the hardware revision level. Revisions are usually backward compatible but include updates to components to improve reliability, thermal performance, or to address parts obsolescence.
Q2: Can a faulty EDCF board cause a “Loss of Excitation” trip? A2: Yes. If the EDCF board fails to report accurate DC feedback, the controller may interpret the lack of signal as a loss of field current, triggering an emergency shutdown to protect the generator from slipping a pole.
Q3: Is the IS200EDCFG1A interchangeable with the IS200EDCFG1AED? A3: Generally, the “AED” revision can replace the base “A” version. However, always check the system configuration files to ensure that the specific hardware revision is supported by your current firmware version.
