GE DS200TCQBG1B
Product Name: GE DS200TCQBG1B – RST Extended Analog I/O Board (Mark V Turbine Control System)
Product Introduction: The DS200TCQBG1B is an RST extended analog I/O board for GE turbine control systems. It serves as a high-density analog interface, reading field signals (temperature, pressure, flow) from RST modules and sending control outputs to valves and positioners. The board provides 16 analog inputs and 8 analog outputs with 16-bit resolution, designed for reliable operation in GE RST turbine control applications.
