DS3815PCBA

About the DS3815PCBA

The DS3815PCBA is a GE component manufactured for the Mark IV gas and steam turbine management system.  The Mark IV uses a triple redundant configuration of microcomputers to carry out continuous diagnostics of the turbine system; if one of these sections fails the turbine will still run under the control of the remaining two sections.  This gives the operator time to fix the failed section and put it back into service. The MKIV monitors such things as turbine speed, temperature, and power supply.

The DS3815PCBA is built with one amber LED and one red LED.  It has four resistor network arrays placed on the board. There are also six jumpers placed on the DS3815PCBA.  Jumpers allow the user to customize some circuits as they choose.

The DS3815PCBA has four TP test points.  There are three connectors for communicating with other PCBs.  These connectors are marked 218A4553-1 AMP 533002-1, 218A4807-P5, and 278A3465.  The last of these have two screw connectors.

The DS3815PCBA has an extractor clip installed in two corners.  The board is factory drilled in each corner. The board is populated primarily with ceramic-covered metal film resistors.  Capacitors may be made of ceramic, polyester film or other material.

The DS3815PCBA has over fifty circuits.  This includes quad two-input NAND gates, presettable 4-bit binary up/down counters, octal buffers and line drivers, and 16-bit HMOS microprocessors.

All technical support for the DS3815PCBA was originally provided by General Electric, as the original equipment manufacturer.  This includes all publications relating to the part, such as manuals and data sheets.
