Products Description
GE DS200TCQAG1BHE RST Analog I/O Board
GE DS200TCQAG1BHE is an RST analog I/O board for GE Mark V Speedtronic gas and steam turbine control system. It acquires and processes analog measurement signals for turbine speed, temperature and pressure, performing signal conditioning and closed-loop control calculation for turbine regulation.
This board has heavy conformal coating for harsh cabinet environments, equipped with onboard signal circuits, LED diagnostic indicators and backplane connectors. It exchanges analog data with other rack boards via the core bus. It is a discontinued legacy PCB, mainly used as surplus or refurbished spare parts for power plant Mark V turbine control retrofit and maintenance.
