GE DS200DSPCH1AEA Digital Signal Processor Control Board

DS200DSPCH1AEA is original USA-manufactured GE core DSP mainboard belonging to DS200 series Mark V Speedtronic platform, 

also named DSPC control card. It acts as central calculation & communication hub of gas/steam turbine control system, 

responsible for real-time analog/digital signal acquisition, algorithm operation, SCR trigger command output and VME bus data exchange with all rack modules. 

The suffix AEA is factory coated PCB version with conformal coating against damp, dust and corrosive gas for power plant harsh environment. 

This model has been discontinued original production, mainly used as maintenance spare for old thermal power, combined cycle power station turbine unit retrofit & replacement.
