Description

The IS200EDCFG1A is an Exciter DC Feedback Board designed for use within the General Electric EX2100 excitation control system. This module serves as a critical interface for monitoring field current and voltage parameters directly at the SCR bridge. By utilizing advanced fiber-optic communication, the board provides robust galvanic isolation and high noise immunity, shielding sensitive control logic from high-voltage transients and electrical interference common in power generation environments.

Features

• Designed specifically for the GE EX2100 series excitation control architecture.
• Facilitates precise field current and field voltage monitoring at the SCR bridge.
• Employs high-speed fiber-optic links for signal transmission to the EISB board.
• Provides superior electrical isolation to prevent ground loops and protect control hardware.
• Supports flexible fiber-optic cable lengths: up to 10 meters for plastic-type fiber and up to 90 meters for hard-clad silica fiber.
• Engineered for reliable operation in demanding industrial temperature ranges.

Applications

This feedback board is primarily utilized in power generation facilities, specifically within excitation control systems for synchronous generators. It is essential for maintaining stable excitation control and protecting the integrity of the control system during high-voltage operations.
