Description

The GE Fanuc DS200SBCBG1A is a dedicated Brake Control Card engineered for the Mark V Speedtronic turbine control platform. This module is essential for managing the mechanical braking sequences of heavy-duty rotating machinery, including turbines utilized in power plants, refineries, and mining facilities. By supervising 12 independent control channels, the card facilitates precise torque application and controlled deceleration, which is vital for protecting equipment during emergency stop procedures and minimizing long-term mechanical degradation.

Features

  • Controls 12 independent channels for comprehensive braking management.
  • Designed for integration within the standard Mark V control rack architecture.
  • High-impedance drive stage architecture ensuring stable operation.
  • Supports both 50 Hz and 60 Hz utility frequencies.
  • Incorporates signal isolation to protect the digital control bus from EMI generated by high-current braking resistors.
  • Robust thermal compensation for reliable operation in harsh environments.
