Product Overview

The IS200EXHSG3REC is a high-performance Exciter High-Speed Relay Driver Board developed by GE Fanuc for the EX2000 and EX2100 excitation control systems. This module is designed to manage high-speed relay operations, including de-excitation and field flashing, which are critical functions in gas and steam turbine applications.

The board supports both simplex and redundant control configurations, ensuring reliable relay control through advanced contactor drivers and signal conditioning circuits. This functionality is essential for fast response and stable voltage regulation, which help maintain generator safety and performance under varying operating conditions.

Technical Specifications

Key Features

• High-speed contactor drive: Controls field flashing and de-excitation with 125V boost for 150ms, then switches to regulated hold current.

• Redundancy support: Works in simplex and redundant 2-of-3 vote configurations, ensuring reliable and robust operation.

• Signal conditioning: Filters and conditions de-excitation signals from EDEX boards to ensure smooth operation.

• Voltage regulation: Maintains stable voltage regulation with ±0.2% accuracy, contributing to system reliability.

• Temperature resilience: Operates reliably in harsh environments with temperatures ranging from -40°C to +70°C.

Application Scenarios

The IS200EXHSG3REC is ideal for:

• Excitation control in gas and steam turbines.

• Generator protection and fast shutdown systems to ensure rapid and safe de-excitation.

• Power plants requiring high-speed relay logic for control and protection systems.

• Redundant control architectures in critical infrastructure applications, ensuring high fault tolerance and reliability.
