    GE DS200RTBAG3AHC Relay Terminal Board
    Manufacturer: GE / Baker Hughes
    Model: DS200RTBAG3AHC
    Series: Mark V / DS200 (Legacy Turbine Control)
    Type: Relay Output & Terminal Board
    Function: Electromechanical relay switching & field termination for turbine protection and excitation systems
    1. Overview
    The GE DS200RTBAG3AHC is a relay terminal board for the Mark V control system, commonly used in turbine excitation and protection circuits. It features **10–12 electromechanical relays** with Form C contacts and **52 screw terminals** for field wiring. The board provides isolated relay outputs for trip circuits, interlocks, and excitation control signals, with surge protection and 1500 V isolation between field and system sides. It is typically mounted in drive or control cabinets for gas/steam turbine applications.
