Description

The IS200EDCFG1ADC is a specialized Exciter DC Feedback Board engineered for the GE EX2100e excitation system. This module is responsible for the real-time acquisition of field current and field voltage parameters directly at the Silicon-Controlled Rectifier (SCR) bridge. By converting these critical analog measurements into high-speed digital signals, the board provides essential feedback to the control algorithms, enabling precise regulation of generator output.

Features

• High-Speed Communication: Utilizes a dedicated fiber-optic link to transmit data to the EISB board in the control panel, ensuring rapid response times.
• Electrical Isolation: The optical interface provides a robust physical safety barrier, protecting sensitive control electronics from high-voltage transients.
• EMI/RFI Immunity: Advanced design architecture ensures immunity to electromagnetic interference, which is critical in high-noise SCR switching environments.
• Precision Measurement: Monitors shunt-based field current and bridge-side field voltage to maintain stable excitation control under varying load conditions.

Applications

This board is a mission-critical component used in large-scale power generation facilities. It is specifically designed for integration within the GE EX2100e excitation control architecture, where it serves as the primary feedback interface for generator field regulation.
