DS3815PABA

Product Description

The DS3815PABA is a smaller PCB manufactured by GE as a component for the Mark IV series.  The Mark IV is designed for gas/steam turbine management. It is built around a group of interconnected microcomputers that monitor the turbine twenty-four hours a day.  This system offers improved application flexibility and an enhanced operator interface with a substantial decrease in the turbine outage rate.

The DS3815PABA has eight light emitting diodes on one edge.  These are labeled zero through seven. All are red. Below these are two  thumbwheel switch components (1A213034GF) marked SW3/MSD and SW4/LSD. Both have ten legend locations.  Each switch may be a different code. The board also has two toggle switches. One of these may be set to WR or LADR and the other to CONT or SS.   The board has three test points, which are placed in the order of TP1, TP3, TP2. These are labeled SIM1, COM, and SIM2.

The DS3815PABA has one PCB mating connector with ribbon cable attached.  This is marked 278A4702P3B. The board has one jumper switch, which may be set either to 2716 or to 2732.  It is populated by four integrated circuits including octal buffers and line drivers with three-state outputs.  

The board is factory drilled for mounting to a larger board.  It is marked with the GE mark and with the code 6BA03. The majority of capacitors on the board are fixed vacuum capacitors.  The majority of resistors on the board are ceramic metal film.

As the original equipment manufacturer, GE was responsible for all tech support for the DS3815PABA, including publications like manuals and datasheets.
