About the DS3800DLIA

The DS3800DLIA is a printed circuit board, or PCB, manufactured by GE designed as part of their Mark IV Speedtronic system. This is a gas and steam turbine control system specifically designed to reduce downtime caused by electronics failure. With built-in redundancies that automatically take over when one chipset has an issue, the Mark IV gives the operator an opportunity to diagnose and repair the damaged PCB with no loss of service. The DS3800DLIA is designed as a load inverter auxiliary card.

The DS3800DLIA has the following specifications:

• the board is factory-drilled for mounting with six holes total, a single hole in each top corner and a double hole in each bottom corner.

• has one ribbon cable connector, marked 278A4702P5A

• has eleven through-hole potentiometers located on the front edge of the board, parallel to the short edges of the board. These are labeled as follows: 1. Gain 2. Comp 3. UV 4. OVA 5. VM 6. SUPP 7. IM 8. VDC 9. FCA 10. FBC 11. FAB

• has eighteen screw terminals. Nine are grouped in parallel lines of three, six are grouped in parallel lines of two, and three are located on the edge of the board.

• has five jumpers. These are located in the center of the board.

• has 30 ceramic metal film resistors of different values.

• has four TP test point rings

• has three yellow capacitors labeled 70801

• has one orange capacitor labeled 50v 20μF.
