Description

The IS200WDIIH3ABB is a board component manufactured by GE as part of the Mark VI system.The Mark VI is one of the last of the Speedtronic systems for gas/steam turbine management released by GE. The IS200WDIIH3ABB is a small rectangular board with a small number of components. The board is drilled in three corners, and also has four additional factory-drilled holes located in a single line parallel to the front edge of the board.The board has two plug connectors on the front surface of the board. These are located on the right edge of the board. The board has a backplane connector connected to the bottom of the board. This is the only component located on the bottom surface.This surface is also marked RA/00.” The IS200WDIIH3ABB has a single heat sink component.It has ten integrated circuits, along with capacitors, resistors, and diodes.The diodes are located in eight parallel lines. There is a single diode bridge rectifier (DN1)with high surge current capability. This rectifier consists of four silicon junctions built into a four-pin D.I.L. package. The IS200WDIIH3ABB has a single metal oxide varistor.Varistors are variable resistors with an electrical resistance that varies with the applied voltage.The board also has two lines of fast acting fuses. These are placed on the board in two lines of eight, and are labeled TR1 through TR16.The board has three lines of components labeled D2, B2, and Z2. The IS200WDIIH3ABB is marked with the manufacturer's logo.Installation instructions can be found using manufacturer datasheets, manuals, and user guides.
