About the DS3800NHVE1B1B

The DS3800NHVE1B1B from GE functions as a high volt card for the Mark IV system. This system was designed for steam/gas turbine control and uses a number of features to streamline management of the turbine system, including automating procedures like startup and shutdown. It can also monitor emissions of air, fuel, and water.

The DS3800NHVE1B1B is a vertically heavy board due to six Bicron transformers attached in two rows of three (part number 218A4886 P1.) The transformers take up a significant part of the board. Clustered inside these two lines are twelve banded carbon composite resistors (gold/black/purple/yellow,) and six polyester film 100V 2.0+/- 10% capacitors. Six light emitting diodes (LEDs) are also located in this area of the board.

Other components on the DS3800NHVE1B1B include five jumper switches (which can be set either to H or to B,) six contact points, two male com connectors (both 218A4807P4,) and many straight-pin headers. The headers are as follows:

• top edge, three 8-position 3 pin, labeled p1, p2, p3

• right edge, five 4-position 2 pin, labeled 01, 02, 03, p, n

• bottom edge, three 8-position 3 pin, labeled n1, n2, n3

All components on the board are labeled. Two edges are marked for alignment, and corners are factory-drilled. There is an additional factory-drilled hole in the exact center of the board.

General Electric provided all the technical support for the DS3800NHVE1B1B and other Mark IV components. This included publications like manuals and data sheets. Necessary information like installation guidelines and maintenance schedules may often be found within these publications.
