IS200JPDCG1A

The IS200JPDCG1A is a JPDC Power Distribution Module from GE's Mark VI. The Mark VI system is part of the Speedtronic series of steam or gas turbine management systems, which has been in use in various forms since the 1960s.

• The IS200JPDCG1A is a printed circuit board with a lot of components. This board uses standoffs and screw mounts to attach to a metal sub-panel. Through board cutouts, this sub-panel adds many connectors, including screw connects and stab-on connectors that utilize surface wire.
• A large vertical component can also be mounted to the bottom right corner of the board, where there is a small rectangular cut-out in the board edge, using the subpanel. This vertical component wires in through surface wiring attached to a two-pin plug and connects to the PCB via a female multi-pin connection.
• A five-position terminal strip is situated next to three small three-position terminal strips on the IS200JPDCG1A. On the board, there are seven toggle switches: one single switch, three lines of three, and three lines of three with a warning sticker that reads, "After withdrawing power, wait 30 seconds before re-energizing."
• Two LEDs, twenty fuses, a male ribbon connector, and 52 plug connectors of various sizes, ranging from 2- to 12-position plugs, make up the board. A jumper switch, a transformer, transistors, varistors, capacitors, resistors, and integrated circuits are among the other components on the board.
• Reference designators are used to identify certain components. Codes, the board ID number, and the round GE emblem are all printed on the board.
