DS3800NGRA1L1E

About the DS3800NGRA1L1E

The DS3800NGRA1L1E regulator board from GE is a component in the Mark IV series.  This series was designed for steam/gas turbine management and can automate some procedures for increased efficiency (startup/shutdown/cooldown.)  It also minimizes downtime of the entire system caused by electronics failure by using integrated chipsets that duplicate all important responsibilities across multiple boards.  

The DS3800NGRA1L1E has the following specifications:

• It is marked A through J on its top edge.

• It is marked 2, then 10 through 80 on its left edge.

• It is factory drilled in all corners.

• It is marked with the codes 6BA04 and NGRA 6DA04.

• It has one Augat connector.  This is a 28-pin female connector

• It has four PCB mating connectors.  These are right-angled connectors. Two connectors are marked 218A4637P4.  Two connectors are marked 218A4637P6.

• It uses primarily ceramic-covered metal film resistors.  

• It uses polyester film capacitors.  Examples of polyester film capacitors on the board include .047 +/- 10% M/e AE 80V, 708A1 M/e 100V 2.0 +/- 10%, and 708A1 .33 +/- 10% A/e 200V.  

• It uses ceramic capacitors.

• It uses fixed vacuum capacitors

The DS3800NGRA1L1E has 25 circuits populating the board.  This includes voltage comparators able to operate from a single power supply of 5.0V, retriggerable one-shots capable of generating output pulses between a few nanoseconds up to 100% of the duty cycle, hex inverters,  Quad SPST CMOS Analog switches, and precision operational amplifiers designed with low input bias and offset currents.

All datasheets, manuals and technical support for the DS3800NGRA1L1E were provided by General Electric.
