DS3815PABA1E1A

Product Description

The DS3815PABA1E1A is a small PCB or printed circuit board made by GE for their Mark IV series.  The MKIV, which was created for gas or steam turbine control, is designed with interconnected microcomputers that distribute all control functions across multiple platforms, with intentional redundant backups to critical controls and protection parameters.  Compared to earlier Speedtronic systems like the Mark I or Mark II, the Mark IV has a substantially decreased turbine outage rate, along with better application flexibility and an upgraded operator interface.

The DS3815PABA1E1A is designed as an auxiliary board for a larger PCB.  It connects and communicates with that larger board via the 278A4702P3B ribbon connector located on one edge.  The board is drilled in all corners for mounting to the larger PCB.

The DS3815PABA1E1A has three test points located on one edge.  These are labeled SIM1, COM, and SIM2. The board has two toggle switches.  One may be set to SS or CONT. The other may be set to LADR or WR. Two thumbwheel switches are placed next to the toggle switches.  These components (1A213034GF) offer ten legend locations, screwdriver thumbwheel adjust, and include stop pins and special rotor markings to create customized interfaces.  This edge also has eight red light emitting diodes, which are numbered zero through seven.

The DS3815PABA1E1A has four circuits, one of which has been updated with the code 9172 P0191.  Other circuits include octal buffers/line drivers designed to improve the density and performance of three-state memory address drivers.  There is also one jumper switch on the board, which can be set either to 2716 or to 2732.

All technical support for the DS3815PABA1E1A was provided by GE.  GE printed and distributed manuals and datasheets for this product.
