IS200JPDDG1A

Product Description

The IS200JPDDG1A is a component created by General Electric for their Mark VI system.  The MKVI is one of the Speedtronic gas/steam turbine management series that, while now obsolete, was considered for decades the most consistently reliable turbine management system on the market by many.  The MKVI includes a central Control Module that takes care of the majority of the monitoring, protection, and control of the turbine system.

The IS200JPDDG1A is designed as a DC power distribution board.  It is used to split one DC power output into multiple loads. The board accepts inputs of 24V, 48V or 125 VDC.   This is one of several branch circuit boards used in the Mark VI system to provide additional distribution of DC or AC power.   The boards are not connected to the PPDA feedback cable.

The IS200JPDDG1A is a rectangular board with six toggle switches and twelve fuses.  The board has six LEDs located on the board to indicate power status. It has seven 2-position plugs located on one long board edge. Six of these are labeled JD1 through JD6 and correspond to the toggle switches.  The board has an additional three plugs on its surface that are also labeled. The board has a single conduction sensor that is labeled “TB1.”

The IS200JPDDG1A is factory-drilled in two corners.  The GE logo is present on the board, as are several codes and the board ID number.  Installation guidelines and other technical support may be found by consulting publications like manuals, data sheets, or user guides that reference this part number.
