DS3800NVIA circuit boardof General Electric’s Mark IV Speedtronic series

Product Description
The DS3800NVIA circuit board is part of General Electric’s Mark IV Speedtronic series. The Mark IV was the first Speedtronic system to use microcontrollers. It was also the first to offer triple modular redundant architecture, where three individual controllers voted on outputs. With this sort of setup, any one controller could be offline due to an issue or maintenance without affecting the overall system.

The DS3800NVIA is a rectangular single-sided board with components mounted on one side only. The board uses through-hole components. Standoffs have been pre-installed on the board to allow for the installation of auxiliary boards. However, it is important to note these auxiliaries are not part of this purchase. The board is also pre-drilled to allow for mounting and carries several codes that will help you determine proper placement and wiring configurations.

The DS3800NVIA has many components mounted to its surface. This includes Augat connectors, integrated circuits, resistors, capacitors, test points, transistors, and diodes. The board also has a line of numbered pins that will help the auxiliary board interface with the main board. Additionally, the board has five LED indicators. Four of these are red and one is yellow.

The DS3800NVIA has a single backplane connector. It also has three toggle switches located in its bottom right corner. These are labeled ground reset, OV reset, and OV test.

Additional information about the DS3800NVIA can be found through original documentation from General Electric. This includes user guides, manuals, and data sheets. If you need replacements of any of these documents, please reach out to our staff.

Product Description

The DS3800DBIB is a small printed circuit board (PCB) designed as part of the Speedtronic (Mark IV) line manufactured by GE. The Speedtronic system is designed to sequence turbine fuel and to sequence turbine systems and their auxiliaries for startup. The Mark IV system is designed with a distributed control system which runs on an array of interconnected microprocessors. When one section of this gridwork fails, turbines will continue to work under the control of other parts of the system. In this way downtime is limited. The DS3800DBIB is designed specifically as an interface board.

The DS3800DBIB is a small daughterboard that works as a plug-in to another, larger PCB. It has been drilled out at the factory, one hole in each corner of the board. This board also has four connectors numbered 1 through 4. It has two small screw mounts covered by black tabs. The first mount is marked C101 and is positioned next to a ring marked TP1. The second is not marked and positioned next to a ring marked TP2. The DS3800DBIB has one capacitor rated 708A1, M/E 200V 1.0 +10%. It also has one blue potentiometer located on the edge of the board that is wired for variable resistance. There are ten resistors and six small capacitors marked 'cr' on the DS3800DBIB PCB
