DS3800HLCA1C1D

About the DS3800HLCA1C1D

General Electric created the DS3800HLCA1C1D PCB (printed circuit board) as a component of their Speedtronic Mark IV steam and gas turbine control system. The Mark IV minimizes downtime by harnessing the power of controlled failure/recovery technology and intentional redundancies. When one PCB in the Mark IV system experiences an issue, its responsibilities are shifted to other circuit boards until it can be repaired and put back into service.

The DS3800HLCA1C1D is marked for alignment on its top edge. It is also marked 6DA03 and 6BA0. It has been drilled in all four corners. Some of the components on the DS3800HLCA1C1D include:

• two toggle switches. There is a test switch (A4627P5) attached to the board with three right-angled prongs, and a reset switch (A4627PII) attached to the board with six right-angled prongs. Both switches are rated at 0.4 VA max.

• three jumper switches

• 1 LED (red) marked test

• four potentiometers or adjustable voltage dividers. These are marked "Hgn," "Hos," "Lgn," and "Os."

• Twelve TP test points. These are individually labeled.

• three resistor networks, which may be used here for analog to digital conversion, or to act as voltage dividers.

• integrated circuits (over 35) including two programmable interfaces, DIPs, EPROMs, and oscillators.

• a large AMD 218A4553-1 connector.

The DS3800HLCA1C1D has several small capacitors located at intervals across the board. Resistors are primarily ceramic metal film resistors.

Technical support for the DS3800HLCA1C1D along with other Mark IV components was originally provided by GE. Please refer to manuals and/or data sheets published by GE for installation guidelines.
