DS3800DLCA

GE Speedtronic Mark IV DS3800DLCA is a printed circuit board and its series of Mark IV gas and steam turbine control systems. The DS3800DLCA functions as a load communication converter card that was built expressly for that purpose. In this way, in the event of a malfunction, control, and communications can be shifted, and the Mark IV system can continue to operate without being shut down while the particular electronic board is evaluated and repaired. The DS3800DLCA was designed with only one mounting option in mind. All four corners of the board are drilled. There is only one test point ring on it. The ring is labeled TP12 and is placed near the potentiometer on the board's edge. There is only one potentiometer on it. The part number is 3069P-1-203. 20A.

• There is one ribbon cable connector on the board's long edge, as well as six communication connections. These run between the labels "Open Com" and "Cov" and are parallel to the potentiometer. Each one is identified by the letters BJ1 through BJ6.
• There are three different types of resistors on the board. There are five capacitors designated 70801 on the PCB. On the border of the DS3800DLCA are the letters 6BA03, DLCA, and 6DA02. A triangle logic buffer sign is also present on the board.
