DS3800NAIA

About the DS3800NAIA

The DS3800NAIA is a printed circuit board from General Electric, designed as part of the Mark IV/Speedtronic line. The Mark IV, designed for gas and steam turbine control, uses integrated chipsets built with overlapping two-out-of-three voting redundancies. This 'controlled failure' technology on critical controls and protection parameters minimizes downtime caused by electronics failure and allows the Mark IV to maximize uptime.

The DS3800NAIA is built with the following specs:

• It is factory drilled.

• It has five integrated circuits.

• It is alignment marked along its top edge and marked '6BA07' on its bottom edge.

• It has two connectors to communicate with other PCBs. These are located on opposite ends of the DS3800NAIA. The female connector (218A4637P2) is on the right side of the board and the male connector (218A4551 AMP) is on the left.

• It has two board extractors. Board extractors allow technicians to insert or extract the PCB from tight locations without touching the circuitry.

• It has three trim potentiometers.

• It has three rotary potentiometers.

• It has one resistor network, located in the bottom left corner.

• It is built with 32 larger yellow polyester film capacitors (200V.) It is also built with multiple smaller polyester film capacitors.

• It is built with multiple ceramic metal film resistors.

Maintenance schedules and installation instructions for the DS3800NAIA may be found in technical support publications such as datasheets and manuals. These were originally provided to the end user by GE.
