Product Description

The IS200PICHG1A is designed as a Phase Interface and Control Board for the Mark VI system from General Electric.  The Mark VI is part of the Speedtronic line of steam and gas turbine management. The Speedtronic line is designed for use on both complex and simple turbine systems.  The Mark VI has scalable hardware that allows it to be easily configured as a Simplex system for a smaller system or as a Triple Redundant system for large, complex one.

The  IS200PICHG1A works within the Innovation Series drives.  The board includes all of the feedback signal processing circuits and gating drivers needs for four dual IGBT modules of the H-bridge phase assembly.   This board has thirteen daughter boards that are soldered onto the primary. Included in the thirteen are:

• Eight IGBT Driver Boards (IS205IGDH)

• Four VCO Feedback Transmitter Boards (IS205VCXH)

• One IGBT Temp Feedback Board (IS205TFBH)

The  IS200PICHG1A board includes three LEDs, one jumper switch, 15 TP test points, 12 plug connectors, three stab-on connectors, and 24 fiber optic connectors. The board is also built with high voltage capacitors, heat sinks, inductor coils, and transformers.

The  IS200PICHG1A includes two logic area ground planes.  This includes a power ground (SHCOM) and a signal ground (DCOM.) Logic circuits supplied by the +5V are referenced to this signal ground.  DC bus overvoltage trip signals are also generated on this board. The jumper switch located on the board is used to reduce the OV trip point.

Technical support for the  IS200PICHG1A was originally provided by GE. Information about this board and its subassemblies may be found in publication number GEI-100309.
