Products Description
GE DS200DTBCG1AAA Contact Output Terminal Board
GE DS200DTBCG1AAA is a contact output terminal board for GE Mark V Speedtronic gas turbine control system. It converts control signals from the main turbine controller into dry contact relay outputs to drive field solenoid valves, relays and auxiliary actuators.
This board is equipped with terminal blocks and bayonet connectors for rack wiring. It provides dry contact output channels for turbine trip, valve control and auxiliary equipment logic. It is an obsolete legacy hardware, commonly used as spare replacement parts for existing power plant Mark V turbine control cabinets.
