About the DS3800NMEC1F1E
The DS3800NMEC1F1E is a PCB created by GE for the Mark IV system. It is designed as a motor exciter control board. The Mark IV was designed for gas and steam turbine management and increased efficiency in these systems by allowing the user to automate some standard processes like shut down and cool down.
The DS3800NMEC1F1E is factory drilled and alignment marked. It has several nylon spacers attached near the edges of the board; these spacers support companion or auxiliary boards while allowing the DS3800NMEC1F1E airspace to keep from overheating. The board is populated with three right-angled mating connectors, all marked 218A4637P2. It also has two male vertical pin connectors. There is one 6 pin right-angled header along the right edge.
The DS3800NMEC1F1E has two jumper switches and one trim potentiometer. One jumper can be set either to OUT or IN, and the other can be set to J33 or J32. Jumpers give the end user options on how to customize the board for their use. The potentiometer has a dial marked with hash marks along with the numbers zero, fifty and 100. The board also has seventeen test points and ten transistors.
The DS3800NMEC1F1E has thirty-seven circuits, including 2-input NAND buffers, voltage comparators, crystal oscillators, 4-bit D latches with low power schottky, and operational amplifiers. Some of the amplifiers are quad 741 op amps with low input offset voltage and current, and low supply current drain.
All technical support for the DS3800NMEC1F1E--including publications like manuals and datasheets--was provided by General Electric.
