DS3800DISA1A is an Isolated Auxiliary Card manufactured and designed by General Electric. It is a part of the GE Mark IV Series. This series was designed for steam and gas turbine control and can be used for a variety of tasks such as sequencing the turbine fuel and its auxiliaries for startup, shutdown and cool down procedures, synchronization of the generator and the system, and monitoring the turbine control and auxiliary functions.

DS3800DISA1A Features

  • The component is factory-drilled at all four corners and has six screw terminals, four in one line and two in the other.
  • The board has 9 plugs on its top edge, numbered 1-9, that serve as connectors to a larger motherboard and are marked with a triangular logic buffer symbol.
  • Two potentiometers are labeled R1 and R2 and are located side by side.
  • The board has two more resistor slots labeled. Ceramic, metal film resistors are intended for use in these two slots.
  • DISA's potentiometers are rated differently. The first is marked 3069P-1-103 and has a resistance of 10,000 Ohms (located at R1). The second (R2) is labeled 3069P-1-503 and has a resistance of 50,000 Ohms.

System Hardware Design

  • The Mark IV panel's hardware design had several goals. One of these goals was to have a base design that could accommodate 95% of the customer panel requirements without requiring any hardware changes other than the removal or addition of an optional card, module, or cable. This goal was to have the software configuration accommodate the customer's requirements. While the design was tested against historical requirements and passed, only time will tell how well we meet the needs of future customers' requirements. Another goal was to make the panel repairable while the turbine was running.
  • Much effort has been expended to achieve a panel configuration in which most of the components can be easily and safely replaced while the panel is energized and running a turbine.
  • As a result, the modules containing the majority of the active components (which are presumably the most likely to fail) are placed near the front doors for easy access. To achieve easy repairability, the Mark IV panel had to be built from physical modules that could be easily handled by one person.
  • With the exception of the black start inverter, which is being redesigned to Mark IV standards, we believe this goal has been met. In order to achieve easy repairability, it was also necessary to make the most of pluggable cables rather than screw terminals for electrical connections.
  • Another advantage of using cables is that it reduces the number of wiring errors in module installation, resulting in more reliable repairs. All variable wiring modules were removed to achieve maximum reliability. Many of them have been upgraded to printed wiring backplanes.
