The IS200EXMDG1APR from General Electric functions as an MD interface card. It is used within the Mark VI Speedtronic turbine control system. This was one of the last and most advanced of several turbine control systems for industrial steam turbines released by General Electric under the Speedtronic umbrella.
The IS200EXMDG1APR is a small board designed to mount easily using the factory drilled holes located at each corner of the board. The board itself carries several codes along its edges, including wiring and ID codes. There is also a barcode located at one edge that will provide additional information. The board also has the GE logo printed within the body of the board to ensure its authenticity.
The IS200EXMDG1APR includes multiple connectors on its surface. This includes two vertical pin connectors that are located parallel to each other. Close to these connectors, there are two additional Augat connectors. One of these is a 3 by 3 connector. The other is a 2 by 3 connector. Finally, there is a right-angled connector with two female connection points and two male pins located along one board edge.
Other board components include a relay, a single resistor, and two MOVs (metal oxide varistors).
Refer to manuals, datasheets, or user guides from General Electric for additional information. The EX2100 manual may be of some help as this part can be used with that Excitation Control subsystem of the Mark VI. If you need additional copies of these instructions due to loss or misplacement, please let our staff know when you are placing your order.
