GE 323A4747NCG1C IS200BPVDG1BR1A Power Distribution

Technical Specifications

The GE 323A4747NCG1C (also IS200BPVDG1BR1A) distributes DC power within Mark VI turbine control systems. This board measures 30.5 cm in length and 25.4 cm in width. It weighs approximately 1.6 kg. The unit accepts 125 V DC input from the main battery bank. Then, it provides six isolated output channels at various voltages. The GE 323A4747NCG1C IS200BPVDG1BR1A stores 256 KB of configuration data in flash memory. It also uses no battery for energy storage. Instead, the board relies on onboard capacitors for 100 ms hold-up.

Design and Integration

This GE 323A4747NCG1C IS200BPVDG1BR1A powers all Mark VI boards from a single source. The 28 V output drives actuator and relay coils directly. Meanwhile, the 24 V channel supplies field I/O modules reliably. The ±12 V and 5 V outputs feed analog and digital circuits respectively. Each channel includes overcurrent protection and individual 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 323A4747NCG1C IS200BPVDG1BR1A 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 83% at nominal load. Each unit undergoes 48-hour full-load burn-in before shipping.
