DS3800NADB1B1B

Product Description

The DS3800NADB1B1B is a PCB manufactured by GE as part of their Speedtronic Mark IV line. The Mark IV, which was designed for gas and steam turbine control, has integrated chipsets with two-out-of-three voting redundancies on all critical controls and protection parameters. The Mark IV uses these intentional redundancies--or 'controlled failure' technology to plan for wear and repair of parts, but with as little downtime as possible.

The DS3800NADB1B1B functions as an analog/digital converter card. It is a larger board and has been designed as a motherboard to an optional auxiliary board (DS3800DADB.) When this auxiliary is installed the capacitance of DS3800NADB1B1B is increased through access to that board's eight capacitors ( 708A1 200V M/E .)

The DS3800NADB1B1B is built as follows:

• There is one LED (amber.) The LED is labeled "p ok."

• There are three test points (TPs.) These are labeled com/sync/aout.

• There are three connectors for communicating with other boards: one female connector(218A4637-p2.) one male connector (218A45533-1 AMP) and one ribbon connector to communicate with its auxiliary board.

• It is alignment marked.

• It has extractor arms installed in two corners.

• It is built with spare PTH for the addition of parts.

• The board is built with multiple integrated circuits. This includes a 12-bit A/D converter with a clock. All digital signals from this chip are DTL/TTL compatible, and the data output is negative-true. It is available in either parallel or serial form.

Tech support for the DS3800NADB1B1B was provided by General Electric. Datasheets, manuals and other publications referencing installation instructions and maintenance schedules may be found through the original manufacturer.
