DS3800HRCA | General Electric Signal Condition Processor Board Mark IV

The DS3800HRCA is a Signal Condition Processor Board manufactured by General Electric, designed for use in the Speedtronic Mark IV Turbine Line. This board functions as a processing daughter board and connects via a long female power terminal, two clips, and two small screws. The board is labeled along one edge with letters for identification. 

The DS3800HRCA features one amber LED and four red LEDs, with each LED secured in place by small black clips. Additionally, the board includes five jumper prongs covered by two protective covers, which facilitate adjustments to energy flow. The board is populated with five yellow capacitors, three blue diodes, two silver diodes, one black diode, and nineteen yellow diodes. It also contains sixteen banded resistors, with the bands indicating the current capacity of each resistor. 

The DS3800HRCA incorporates thirty-three EPROM memory chips, which are programmable and can be updated. Additionally, the board includes four EEPROMs, which are non-volatile memory chips that cannot be updated. EPROMs and EEPROMs are visually similar, but EPROMs can be identified by a small circle on the top, distinguishing them from EEPROMs.
