The DS3800HLNF1D1B is a control card for a General Electric turbine control system. This particular printed circuit board is designed to fit into a Mark IV Speedtronic system. Speedtronic systems, which began with the Mark I in the 1960s, have been GE’s primary offering for industrial turbine control, with the Mark IV being the first of these systems to offer a more complex architecture with built-in redundancies that helped to reduce downtime and increase the overall efficiency of the system.
At 1.15 pounds, the DS3800HLNF1D1B is a larger circuit board. This weight is before the addition of internal or external boxing as well as any sort of padding we may use to protect components for shipment. Your actual shipping weight will be higher. Components can be combined together in one package for lower overall shipping costs.
The DS3800HLNF1D1B is built with a backplane connector to help the board communicate with the larger rack system and other components within it. The board also has a right-angled connector near its front edge for the addition of another cabled connector. Before the Mark IV, most Speedtronic systems used terminal screw-type connectors; with the advent of this system connectors changed over to plug-in types to allow for faster change-out of components. This front edge also includes extractor clips to allow the board to be pulled from its location more easily during replacement.
Other board components on the DS3800HLNF1D1B include FPGAs, integrated circuits, DIP switches, and resistors. Details regarding this board’s installation and maintenance can be found through General Electric manuals and user guides.
