About the DS3800NSCC1D1A

The DS3800NSCC1D1A is a speed/current regulator board created by GE for the Mark IV series.  The series was created for gas or steam turbine management and has been built upon a system of triple-redundant back-ups on all critical controls and protection parameters.  These intentional redundancies help limit the possibility of electronics-caused downtime within the system.

The DS3800NSCC1D1A can communicate with other printed circuit boards by utilizing its two PCB mating connectors.  These are marked 218A4637P1 87936-1 and 218A4553-1 A/mp 533002-1. There is also one Augat connector located near the center of the board.  

The DS3800NSCC1D1A is built with one amber light emitting diode.  This is labeled IMOK. It has fourteen test points. All test points are also individually labeled.  

The DS3800NSCC1D1A has two extractors fitted to the board.  These nylon clips aid technicians with insertion or extraction of the DS3800NSCC1D1A, especially from tight locations.  The clips can be used both as handles and as levers to help pull the board from its position.

The DS3800NSCC1D1A is built with over twenty circuits, including quadruple 2-input OR gates and quad differential comparators, which have a common-mode input voltage range and a differential input voltage range equal to the maximum rated supply voltage.  

The DS3800NSCC1D1A  is populated with ceramic covered metal film resistors.  Capacitors may be polyester film, ceramic, or other material.  The top edge of the board is alignment marked.

GE, as the original equipment manufacturer, was responsible for all technical support for the DS3800NSCC1D1A.  This included publications like datasheets and manuals, which will reference this part.
