DS3815PCLA

About the DS3815PCLA

The PCB DS3815PCLA is manufactured by GE as part of their Mark IV series.  This series is designed for gas/steam turbine management and supersedes earlier Speedtronic systems like the MKI and MKII.  The MKIV is built with more application flexibility and an improved operator interface compared to older systems. It has a higher reliability rate and a decrease in the turbine outage rate.  

The DS3815PCLA is built with over sixty integrated circuits.  This includes High-speed CMOS static RAM chips, hex inverting gates, octal tri-state buffers/line drivers/line receivers, and 2-input positive-NAND Schmitt triggers.  The board has five resistor network arrays located on the board. Resistor network arrays are sometimes used for voltage division.

The DS3815PCLA has two Augat connectors.  It is built with two 218A4637P1 mating connectors; these are right-angled male connectors.  It also has one 218A4553-1 AMP 533002-1 connector. The board has two test points.

The DS3815PCLA is built with three light emitting diodes.  This includes two red LEDs and one amber LED. It has eighteen jumper switches.  Jumpers give the option of finishing off circuits as desired. J15 and J16, for example, can be set to IN or to OUT.  J8 can be set to INT or EXT. Other jumpers may be set to one or zero, or 2k or 4k.

The DS3815PCLA is factory drilled at all corners.  Extractors are installed in two corners. Capacitors are usually fixed vacuum, but the board has several capacitors made of other material.  Resistors tend to be made of ceramic-covered metal film.

General Electric provided all technical support for the DS3815PCLA, including publications like manuals and data sheets.
