Product Description
This DS200DMCBG1 General Electic printed circuit board or PCB for short was originally introduced as a member of their Mark V Series, one of the later General Electric product series to feature the patented Speedtronic technology first introduced with their rollout of the Mark I Series in the late 1960s. The Mark V Series, while one of the more recent GE Speedtronic Series, is considered a legacy series due to its eventual discontinuation by the original manufacturer, and has specific applications in the control and management systems of wind, steam and gas turbine automated drive assemblies. This DS200DMCBG1 printed circuit board is more explicitly-definable as a DOS DUP Processor Board, the functional description that it received in original General Electric and Mark V Turbine Control System Series instructional manual documentation. While this DS200DMCBG1 PCB does exist as a Mark V Series DOS DUP Processor Board in its own right, it is additionally considered to be the original DOS DUP Processor Board developed for installation in the Mark V Series automated drive assembly, as denoted through the absence of any significant revision indicators in the DS200DMCBG1 functional product number.
Hardware Tips and Specifications
Similarly to any product offered in our catalog of new and reconditioned General Electric printed circuit boards, this DS200DMCBG1 DOS DUP Processor Board necessitates its own particular series of hardware component inclusions and specifications to achieve normative functional status as a DOS DUP Processor Board. For starters, the GE DOS DUP Processor Board contains three 26-pin connectors, one 40-pin connector, and 19 jumpers. The board also has 2 LEDs, included in its assembly for diagnostic fault detection purposes. The DS200DMCBG1 GE DOS DUP Processor Board is also populated with two fuses that the servicer can replace, if necessary. This DS200DMCBG1 DOS DUP Processor Board benefits from its possession of a General Electric functional product number, given the relative unavailability of its original instructional manuals on the internet for research purposes. The DS200DMCBG1 functional product number begins with the functional DS200 series tag, which identified this DS200DMCBG1 printed circuit board as a domestically-manufactured General Electric product and as a Mark V Series printed circuit board with a normal style of assembly. Some of the other details revealed by functional naming elements in the DS200DMCBG1 functional product number include the DS200DMCBG1 DOS DUP Processor Board's DMCB functional product acronym, its normal style of printed circuit board coating, its group one Mark V Series product grouping, and its possession of no functional or artwork revision in its normal assembly.
There are General Electric-specified steps that must be followed to perform the DS200DMCBG1 PCB's safe fuse replacement. You can inspect the board if you suspect there is a problem. Locate the board and inspect the fuses and check that the element in the fuse is blown. Remove all power from the drive before you touch any components, cables, or boards. Use a tester to verify that power is removed from the drive before proceeding. Also, be aware that power resides in the DS200DMCBG1 PCB's greater automated drive for 20 seconds after power is removed. You might have to remove the board to replace the fuse. Use a screwdriver to remove the four screws and washers that hold the board in place. Keep the screws and washers together and store them because you need them to reinstall the board. Note where the cables are connected to the board before you remove them from the board. Place the board on top of a static protective bag and remove the blown fuse. You must only use an exact replacement fuse. Refer to the information for the rating of the fuse before you replace it; if the fuse is not the same rating, it might allow more current into the DS200DMCBG1 board and damage components.
