DS3800NADA

About the DS3800NADA

The DS3800NADA printed circuit board was manufactured by GE to act as an analog to digital converter card within their Mark IV Speedtronic system. The Mark IV series was designed for steam and gas turbine control. The Mark IV was one of the first systems designed using integrated chipsets built with overlapping two-out-of-three voting redundancy on critical control and protection parameters. This 'controlled failure' technology keeps the Mark IV running even when an individual board experiences an electronics issue by shunting control to other boards that are backups to that board.

The DS3800NADA has been built with the following specs:

• Three crossbars are positioned across the long dimension of the board. This stiffens the board and reduces the risk of bending.

• One amber LED is positioned on the right edge.

• Three test points are positioned above the LED.

• Two potentiometers are positioned on the top edge.

• The board has one connector male and one connector female designed for communicating with other modules. The connectors are placed on the edges of the DS3800NADA.

• The board has twenty-six integrated circuits.

• The board has a set of spare PTH located near the upper middle of the board.

• The board has been drilled in all four corners. Two extractor clips have been installed in the upper and lower right corners.

• The board has been built with small capacitors and multiple metal film resistors.

Installation guidelines for the DS3800NADA can be reviewed by reading through technical support publications from General Electric. GE published data sheets and manuals for the DS3800NADA.
