The DS200DMCAG1AHC is a PC Interface Board made by GE for its Mark V series of Speedtronic turbine control systems. It is a legacy series and is no longer supported by GE. It may be somewhat hard to find, but AX Control does try to keep it stocked as either a new surplus or refurbished part.
The DS200DMCAG1AHC is a very large rectangular printed circuit board that contains many different components. Along the edges and corners, there are factory drilled holes that can be used to mount the board into place. Along the bottom edge are three connectors that have male pin connections. In the top, left corner of the board are a series of four blue capacitors. There are nine resistors that are scattered around the capacitors. Next to the series of four capacitors is a smaller blue capacitor that is directly next to an inductor coil. There is a female RS-232 26-pin d-shell connector that has the ability to screw into place. Next to that is a series of large integrated circuits. Above the RS-232 connection is an integrated circuit and four resistors. Below the relays are fourteen integrated circuits and fourteen resistor network arrays. Below the inductor coil and RS-232 connector are seventeen resistors, twenty-seven integrated circuits, and four resistor network arrays. There are also a good number of diodes scattered in this section. Below the four capacitors are four more relays and a very small auxiliary daughterboard that has eight integrated circuits. There are ten resistors next to the small circuit card.
