The IS200BICIH1ADC is a GE Mark VI Bridge Interface Controller Board. This circuit board was designed as part of the MK VI platform for the control of industrial gas and steam turbine systems. The IS200BICIH1ADC uses an IGCT switching device and mounts into an Innovation Series rack along with an IS200CABP board.
The IS200BICIH1ADC has nineteen individual daughterboards soldered to its surface of two types: eight DVAA dual voltage controlled oscillator modules (IS205DVAA) and eleven analog comparator modules (IS205AOCA). Each of the daughterboards has its own function; for example, the DVAA board will provide two identical circuits, which are VCO circuits, as well as a pulse-train compatible output. The IS200BICIH1ADC also has a digital signal processor that acts as a coprocessor for a nearby DSPX board.
The IS200BICIH1ADC includes two FPGAs (field-programmable gate arrays) for logic functions, PWM timers, and control and status registers. The board has both analog and digital inputs and outputs. Some connectors are mounted into the board’s front faceplate. The faceplate also includes a removable panel that allows access to a row of TP test points.
Other components on the board include right-angled connectors on the rear edge of the board, over forty integrated circuits, resistors, capacitors, metal oxide varistors, and diodes. The board is designed with components on both the front and rear surfaces.
