The DS200DCCAG4A is a DC Power Feedback Board made by General Electric. It is a part of the Speedtronic Mark V turbine control system. It is no longer receiving any type of support from GE and may be a little hard to find. AX Control does try to keep it in stock, but please call us directly for the availability of the DS200DCCAG4A.
The DS200DCCAG4A has many different jumpers. The JP1 is typically disabled but can be enabled to allow it to write to the EEPROM. JP7 and JP8 are typically left unused. JP15 is normally in the in/enable position which enables the oscillator. JP19 is a water flow input. JP20 is a megawatt input. The JP21 is a water flow and megawatt input. JP23 is a direct memory access connection. JP22 is an I/O master oscillator connection. JP31 is an I/O network communication connection. JP32 is a drive system function and only use the 1-2 position. Jp-33 is a 320 co-processor oscillator enabled connection. JP-34 is a microprocessor timer connection. JP-35 is a 27C1010 or 170 EPROM chip. JP-36 allows 128 or 256K RAM chip selection.
The DS200DCCAG4A should be mounted into a Mark V control cabinet. The cabinet should be used only in indoor locations and should be kept away from liquids and corrosive materials. It should be stored in a clean, dry environment. For more information about the DS200DCCAG4A and its installation processes, please consult the GE Application Manual GEH-6195F. Only trained professionals should attempt to install the DS200DCCAG4A.
