Product Description
This DS200KLDCG1AAA printed circuit board product offering was originally designed and manufactured by General Electric, specifically for use in their Mark V Turbine Control System Series. As you surely have been able to ascertain from its extended name, the Mark V Series that this DS200KLDCG1AAA printed circuit board exists as a member of has specific applications in the control and management systems of steam, wind, and gas turbine automated drive assemblies, and is considered a General Electric legacy series as its production has been discontinued in the years following its initial release. The Mark V Turbine Control System Series that this DS200KLDCG1AAA product offering exists as a component member of is additionally one of the final General Electric product series to make use of their patented Speedtronic control system technology, which was first released alongside the rollout of the Mark I Series in the late 1960s. This DS200KLDCG1AAA printed circuit board has a true functional product description as a Key/LED/Display Board, based on this functional description's inclusion in pertinent Mark V Turbine Control System Series instructional manual materials. While this DS200KLDCG1AAA PCB is definable through this functional description, it is not the original Key/LED/Display Board manufactured for use in the Mark V Series; that would be the DS200KLDCG1 parent printed circuit board missing all three of this DS200KLDCG1AAA product's revisions.
Hardware Tips and Specifications
As with any circuit board available in our inventory of new and used General Electric Mark V Series products, this DS200KLDCG1AAA PCB makes use of its own series of functionality-introducing hardware component inclusions and specifications. For starters, this DS200KLDCG1AAA printed circuit board is equipped with many of the various voltage-limiting and storing hardware components seen in other static-sensitive Mark V Series offerings, including numerous resistors, capacitors, and diodes. The base circuit board of this DS200KLDCG1AAA product is additionally insulated through this DS200KLDCG1AAA device's inclusion of a normal style of PCB coating, which envelops and insulates individual DS200KLDCG1AAA product hardware components attached to its base circuit board on a functional priority basis. Before making any ultimate purchase decision on this DS200KLDCG1AAA product, it is important to realize the following hardware component and specification information has likely been altered as a function of this DS200KLDCG1AAA PCB's adoption of two A-rated functional product revisions and an A-rated artwork revision.
The GE Key/LED/Display Board DS200KLDCG1AAA features 32 LEDs, twenty-one 4-character displays, and one jumper. The GE Key/LED/Display Board DS200KLDCG1AAA also features one 40-pin connection strip on the rear of the board. The jumper on the board is used to modify its behavior by changing the position of the jumper over the pins. For example, if the jumper covers pins 1 and 2 you can move the jumper to cover pins 2 and 3. The documentation that came with the original board describes the jumper and how moving the jumper changes the behavior of the board. However, some jumpers are for use by the factory only and are not to be moved by servicers. In that case, the jumper is used for testing during manufacturing and the operation of the board with the jumper in the alternate position is not supported. Refer to the information supplied with the board for more information.
The DS200KLDCG1AAA board is attached to its greater Mark V Series automated drive cabinet with screws inserted in the four holes in each corner. The holes align with the screw holes in the cabinet rack in the drive, and were drilled at the GE factory to include a ringed insulation material. Before you remove the defective board, note where the board is installed and also how cables are routed in the cabinet. Cable routing is important because it protects the DS200KLDCG1AAA and its greater Mark V Series drive from interference caused by high-voltage current if a signal cable is too close to a high-voltage cable. Also cable routing helps maintain proper air flow. Improper cable routing might block air flow and cause components to heat up.
