Product Description

The IS200FCGEH1A is a PCB component designed for the Mark VI system. The MKVI turbine control system is part of the Speedtronic series for gas or steam turbine management that started with the Mark I and has continued through the Mark VIe.  The Mark VI is a full system solution that includes the hardware and the software for turbine control. The MKVI is a fully programmable control system that uses 32-bit floating point data in a QNX operating system with scheduling, multi-tasking, real-time applications, and fast context switching.  

The IS200FCGEH1A is an LCI Control/Gating Exciter Board.  The PCB is used to interface signals between the motor field exciter and the LCI drive.   The main functions of the board are conditioning of voltage and current feedback signals from the LCI processor board to the exciter bridge.  The board also relays cell gating commands from the LCI processor board to the exciter. The IS200FCGEH1A can also detect ground faults from the DC exciter.  

The IS200FCGEH1A has a front faceplate attached to the PCB.  The faceplate is built with an LED labeled IMOK and another LED labeled ACTIVE.  The front faceplate has two openings that allow access to twenty-eight TP test points.   These TP test points are all labeled on the front of the panel.

The IS200FCGEH1A board has four connectors, including two 96-pin VMEbus connectors and two 20-pin cable connectors.  The 20-pin cable connectors are for factory use only. The board also has several integrated circuits, capacitors, and resistors.   More information about the board may be found through GE publication GEI-100233.
