The IS200EDCFG1A is an Excitation DC Feedback (EDCF) board used within the General Electric EX2100 excitation control system. This feedback board is responsible for measuring the excitation current and excitation voltage at the SCR bridge and communicates with the EISB board located in the control cabinet via a high-speed fiber-optic link.
Functions
- Measures the excitation current and voltage at the SCR bridge.
- Amplifies and processes the acquired excitation current and voltage signals.
- Transmits the processed current and voltage signals to the EISB board via a fiber-optic link.
- Features an onboard DC/AC power converter capable of converting an external power source into the specific voltages required for the operation of the entire circuit board.
Signal Process
As illustrated in the figure on the left, the IS200EDCFG1A connects to the system's 24 VDC power supply. Utilizing its onboard frequency converter and DC-to-DC converters, it generates various DC output voltages—specifically ±24 VDC, ±15 VDC, and +5 VDC—which provide the essential power required for the entire circuit board's operation and feedback functions, while also contributing to the stability and accuracy of signal transmission. Furthermore, as depicted in the figure, the SCR bridge supplies excitation voltage and current to the IS200EDCFG1A feedback board; after being processed by the onboard amplifiers, these signals are transmitted via a fiber-optic link to the EISB board, where they are utilized by the central processor for excitation control.

FAQ
1. What is the function of IS200EDCFG1A?
—The main function of this feedback card is to provide feedback on the acquired excitation voltage and current to the EISB board.
2. How to select this product?
—IS is the manufacturer (DS & IS for GE in Salem, VA); 200 is the assembly level; EDCF is the functional acronym; G1A is the hardware form; the last two letters are the functional revision and artwork revision.
3. How to determine if IS200EDCFG1A is operating normally?
—Onboard PSOK indicator light. This indicator light is solid green when the feedback board is operating normally.
4. What power supply does IS200EDCFG1A require?
—It requires an External ±24 VDC power supply.
Application Case: At a steel plant, the site of a large synchronous compressor faced significant challenges due to strong electromagnetic interference, high-frequency harmonics, and the necessity for long-distance communication, which prevented the accurate transmission of excitation feedback signals. Following the installation of the IS200EDCFG1A feedback board, the system's resistance to interference was significantly enhanced.
Customer Comments: The Site Control Manager provided the following feedback: "Since we replaced the unit with the IS200EDCFG1A feedback board, the excitation feedback signals received in the control room have been remarkably precise. This allows us to monitor the compressor's real-time operating status at any moment, and we have experienced virtually no unexpected shutdowns caused by inaccurate data measurements."
