Signal Processing & Isolation
The IS200EDCFG1ADC uses differential amplifiers to process low-level signals from the field shunt and voltage taps. These signals drive voltage-controlled oscillators, which transmit data via fiber optics. The board supports both plastic and hard-clad silica fibers for flexible installation distances.
Power Supply & Regulation
An external ±24 Vdc source powers the board. Internal regulators generate +15 Vdc, –15 Vdc, and +5 Vdc for signal conditioning and logic circuits. The green PSOK LED confirms proper voltage regulation.
Application & Compatibility
This module integrates seamlessly with GE’s EX2100 excitation control systems. It supports accurate feedback for field voltage and current, enhancing system stability and performance. The IS200EDCFG1ADC is ideal for high-noise environments requiring isolated signal transmission.
