The DS3800HXFC1J1F is a General Electric PCB designed for the Mark IV system. The MKIV is GE’s third commercially available Speedtronic gas/steam turbine management system. It is the first built with integrated microcomputers that work together twenty-four hours a day to monitor the turbine for issues like high pressure, fire, vibration, and loss of flame. The MKIV can also take care of controlling speed, temperature, control sequencing, and startup and shutdown.
The DS3800HXFC1J1F has over forty circuits on its surface. Quad two-input NOR gates, tri-state buffers and line drivers with 400 mV of hysteresis, and hex/quad D flip-flops are included in this. The board has six network arrays and eight jumper switches. Jumpers allow the user to finish circuits as they choose. Some of the jumpers on this board may be set between “zero” and “one.”
The DS3800HXFC1J1F has four TP test points, three light emitting diodes (one amber, two red,) and one toggle switch. Connectors include a 218A4553-1 A/mp 533002-1 female right-angled, a vertical pin male connector, and a M83503/24-19 8535 male right-angled connector.
The board is alignment marked and factory drilled. Extractor clips, which are inserted into two corners, can be used by technicians as a handle so as to avoid touching components and circuitry. Extractor clips add a lever point to the board, which helps technicians push/pull the board out of place during extraction from tight locations.
All components on the board are labeled. Technical support for the DS3800HXFC1J1F was provided by GE, including end-user publications like data-sheets and manuals.
