DS3810MMBA

About the DS3810MMBA

The DS3810MMBA is a printed circuit board by GE designed as a component for the Mark IV series. The Mark IV is built to take care of shutdown, startup, speed control, temperature control, turbine protection, control sequencing, and power supply.  It has a significantly lower rate of turbine outage when compared to earlier Speedtronic systems.

The DS3810MMBA has the following specifications and components:

• It is alignment marked and factory drilled.

• It has one mating connector, marked 218A4553-1 A/mp 533002-1.

• It is marked with the codes 6DA02 and 6BA02.

• It has extractor clips installed in two corners. Extractors give technicians both a lever point and a handle.

• It is built with four very small auxiliary boards.  Three boards are marked 304A8483G5, “8k x 8 RAM.” The other board is marked 304A8483G9, “8K x 8 EEPROM.” Boards connect to the motherboard via two rows of board-to-board pins (one row of seven and one row of six.)  Each board has an additional three b-2-b pins located next to it. On the opposite side of the boards, there are eight jumper switches next to each.

• It has thirty-seven jumper switches.  Jumpers are placed in five groups: one group of five jumpers in the upper left corner, then eight jumpers next to each auxiliary board.  Each row of eight is labeled Quad A/Quad B/Quad C/Quad D.

• It has eleven resistor network arrays.

• It has one toggle switch.

• It has one transistor.

• It has forty circuits.  Circuits include CMOS Static RAM organized as 8K x 8.  This has an address access time as fast as 15 ns. All inputs and outputs are TTL-compatible.  It also includes two-input positive-OR gates and octal buffers and line drivers.

Technical support for the DS3810MMBA was originally provided by General Electric.  This includes publications for the end user like datasheets and manuals.
