Description

The IS200JPDDG1A is a PCB component created for the Mark VI system.The Mark VI system is part of the Speedtronic line of gas/steam turbine management that General Electric has developed and released for over three decades.While the Speedtronic line is now obsolete, for a long time these systems were considered by many to be the most consistently reliable heavy-duty turbine management systems available on the market.The Mark VI was one of the last of the Speedtronic systems developed and includes a central Control Module connected to a PC-based operator interface that allows the user to access most system data from one place. The IS200JPDDG1A is one of several branch circuit boards in the Mark VI system. These boards are designed to provide additional distribution of ac/dc power for the output of core PDM elements.The IS200JPDDG1A is a dc power distribution board used to distribute a single dc power output into multiple loads.Inputs to this board may be 24V, 48V or 125 VDC. The IS200JPDDG1A is built with six toggle switches to help distribute and turn on/off the loads exiting the board.Each of these toggle switches is paired with an indicator LED. The toggle switches also correspond to two fuses each.Each fuse is marked as positive or negative. The board has ten plug connectors and a single component marked TB1.” Eight plugs are two-position plugs; six of these correspond to the toggle switches on the board. The board is built with resistors and diodes.
