GE IS200EDISG1A IS200EDISG1AAA Power Distribution Board

Technical Specifications

The GE IS200EDISG1A (also IS200EDISG1AAA) distributes DC power to Mark VI turbine control modules. This board measures 30.5 cm in length and 25.4 cm in width. It weighs approximately 1.5 kg. The unit accepts 125 V DC input from the main battery bank. Then, it provides four isolated output channels at 28 V, 24 V, 15 V, and 5 V. The GE IS200EDISG1A IS200EDISG1AAA stores 128 KB of configuration data in flash memory. It also uses no battery for energy storage. Instead, the board relies on onboard capacitors for 50 ms hold-up.

Design and Integration

This GE IS200EDISG1A IS200EDISG1AAA powers all Mark VI boards from a single 125 V DC source. The 28 V output drives actuator and relay coils directly. Meanwhile, the 24 V channel supplies field I/O modules reliably. The 15 V and 5 V outputs feed analog and digital circuits respectively. Each channel includes overcurrent protection and status LEDs. Therefore, the board simplifies system wiring significantly. For a similar power component, see the RMS-TSG-TZ-C on Alibaba. However, that static trip relay focuses on protection rather than power distribution.

Reliability and Operation

The GE IS200EDISG1A IS200EDISG1AAA operates from -30°C to +65°C. Its capacitor-based design eliminates battery replacement needs. Consequently, you reduce maintenance costs substantially. The board meets GE’s efficiency standard above 82% at nominal load. Each unit undergoes 48-hour full-load burn-in before shipping.
