Products Description
GE DS200DTBDG1A Contact Output Expansion Terminal Board
GE DS200DTBDG1A is a contact output expansion terminal board for GE Mark V Speedtronic gas and steam turbine control system. It expands discrete output termination capacity, serving as the wiring interface between the main turbine controller and field actuators, relays and solenoid valves.
This board is fitted with dual terminal blocks, multiple test points, jumpers and 34-pin connectors for signal routing and circuit inspection. It handles auxiliary control and interlock output signals for turbine systems. It is a discontinued legacy board mainly used as spare replacement parts for existing power plant turbine control cabinets.
