GE IS200EXHSG3A IS200EXHSG3AEB | Relay Driver Board

Technical Overview of the GE IS200EXHSG3AEB for Mark VI Systems

The GE IS200EXHSG3A IS200EXHSG3AEB drives high-current contactors with exceptional speed. This board belongs to the Mark VI series from General Electric. It manages excitation circuits to protect turbine generators. Therefore, it ensures stable field flashing and de-excitation processes.

Compact Mechanical Design of the GE IS200EXHSG3AEB

This module measures 12 cm in width, 10 cm in height, and 2 cm in depth. The GE IS200EXHSG3AEB weighs approximately 0.15 kg, which simplifies panel mounting. This board uses a single rigid PCB construction. Consequently, you can install it in tight control cabinets without extra support.

Electrical Interfaces and Component Configuration

The GE IS200EXHSG3AEB provides eight position-plug connectors for field wiring. Each connector supports between 2 and 12 positions. This board contains 12 relay drivers for independent channel control. It also includes four electrolytic capacitors for local energy storage. These capacitors deliver instantaneous current during relay switching events.
