About the DS3810MMAB1A1A

The DS3810MMAB1A1A is a PCB designed by GE for the Mark IV series.  The Mark IV is GE’s gas and steam turbine management system. It can manage such things as startup, speed control, temperature of the turbine system, control sequencing, shutdown, and power supply. The Mark IV is designed with more application flexibility and a better operator interface compared to earlier Speedtronic systems and experiences a decreased turbine outage rate.

The DS3810MMAB1A1A is built with twenty-six jumper switches and nine resistor network arrays.  Twenty-four of the jumpers are positioned in four lines of six. These correspond to four small auxiliary boards mounted to the surface of the DS3810MMAB1A1A.  The boards, which are labeled either 304A483G5 or 304A8483G9, are connected to the board using two lines of board-to-board pins, thirteen in total. A resistor network array sits on the other side of each of these boards from the jumper switches.  The primary board is marked around these components (the jumpers/resistor networks/auxiliary board) as a ‘Quad.’ There is an A, a B, a C and a D Quad marked on the board.

The DS3810MMAB1A1A has one toggle switch.  It has one red LED. The board has one PCB mating connector (218A4553-1 A/mp 533002-1.)  It has been marked for alignment and factory-drilled. Extractor clips are inserted in two corners.

There are thirty-nine circuits on the surface of the DS3810MMAB1A1A.  This includes electrically erasable PROMs, oscillating chips, and octal buffers and line drivers.  

All technical support for the DS3810MMAB1A1A--including datasheets and manuals--was provided by GE.
