Product Description

The IS200BICIH1AEC circuit card was designed and marketed by General Electric as part of the company’s Mark VI Speedtronic system.  The MKVI is used to fully integrate control, monitoring, and protection of the generator and mechanical drive applications within industrial hydro, steam, and gas turbine systems.  The Speedtronic line of products has been part of GE’s offerings since the late 1960s. 

The IS200BICIH1AEC functions as a Bridge Interface Controller card.  It is used within bridges that have IGCT (integrated gate commutated thyristor) switching devices.   The board typically mounts within an Innovation series rack, interfacing with a CABP Control Assembly backplane.  

The IS200BICIH1AEC is a complicated board with nineteen daughterboards soldered to its surface.  These include IS205AOCA Analog Comparator Modules along with IS205DVAA Dual Voltage Controlled Oscillator modules.   The AOCA boards are used to compare an input reference voltage to input voltage signals.   The DVAA boards create two VCO circuits. 

The IS200BICIH1AEC has two FPGAs on its surface.  These provide the logic functions necessary for the board to properly operate.  The board also has two backplane connectors along with three plug connectors, a single LED indicator, and eight TP test points.  The LED is mounted into the front faceplate and will indicate a fault condition by failing to light. 

For a more detailed explanation of the board’s components and use, please refer to documentation from the OEM.  This may include manuals, user guides, and data sheets. Make sure to read all handling precautions and replacement procedures in these guides before continuing with the replacement of your board.
