DS3800NGRA1E1A

Product Description

Designed by GE as a regulator board, the DS3800NGRA1E1A fits into the Mark IV series.  The Mark IV was designed for steam/gas turbine management and automates some procedures (shutdown/startup/cooldown) for increased efficiency.  The system may also be used for fuel, air and water emissions monitoring.

The DS3800NGRA1E1A is built with integrated circuitry, including twenty-five circuits.  Circuits one through three (U1-U3) are marked on the board as rigid envelope terminals. No other information is given about these circuits.  Other circuits on the board include LM311 voltage comparators. These circuits operate from a single 5V supply with a power consumption of 135 mW at +/- 15V.   The output from these circuits will be fast and stable with fast input signals and low source impedance. Precision amplifiers, hex inverters, and analog switches are also used on the DS3800NGRA1E1A.  

The DS3800NGRA1E1A has five connectors located on the board.  This includes one female Augat connector with 28 pin locations.   Two 218A4637 connectors populate each of the short edges of the board.  Each edge includes one P4 and one P6 right-angled connector.

The DS3800NGRA1E1A is built with metal film resistors.  Capacitors vary, but polyester film, ceramic, and fixed vacuum capacitors are all used on the board.  

Alignment markings have been placed on two edges.  Corners have been factory-drilled. Board components are marked.  

GE provided all the original technical support for the DS3800NGRA1E1A, including publications like manuals and datasheets.  These publications can be an excellent resource for the user who is looking for information on installation or maintenance schedules.
