About the DS3800NASB

General Electric manufactured the DS3800NASB PCB as a component of the Speedtronic Mark IV system. The Mark IV, designed for gas and steam turbine control, has integrated chipsets that automatically take over the responsibilities of damaged boards in order to keep the system up and running. The Mark IV can create nearly automatic sequencing for the turbine system and its auxiliaries for startup, cool down and shut down procedures.

The DS3800NASB has the following specifications:

• -factory-drilled at several points on the board. This includes twice in each corner, offset from each corner by a short distance, and in the center of the board.

• -alignment-marked (A-J and 10-80.) Marked '6BA03.'

• -has 14 TP test points. It is worth noting that while TP1-TP10 all sit along the bottom edge of the board, they are not in numerical order.

• -has male connectors on all four sides of the boards. In the case of two sides, the connector is a two-pronged, 90 degree angled connector. The third side has one of these connectors and four five-prong male connectors. The fourth side has a 12 prong male connector.

• -has three transistors. Two are small transistors. The other is a larger Motorola NPN 2 pin transistor designed for general purpose switching and amplifier applications.

• -has one yellow capacitor marked 708D1 600VDC +/- 10% m/e

• -is built with seven ceramic (Cera-mite) disc capacitors of varying capacity.

• -has seven integrated circuits.

• -has two transformers located on the right side of the board.

• -has two potentiometers.

• -is built with ceramic covered metal film resistors of differing values.

Installation guidelines and maintenance schedules for the DS3800NASB can be found within technical support publications from the original manufacturer.
