Product Description:

  • The IS200EGDMH1A is a General Electric Mark VI PCB/Printed Circuit Board component. The Mark VI is GE’s fifth gas/steam turbine management series under the GE Speedtronic name.
  • This PCB employs an EXAM card on both the ac and dc sides to detect any field ground leakage current anywhere in the generator’s field circuit to ground.
  • In simplex systems, a single EGDM board is employed. For redundant systems, three are required.
  • The three boards are then configured as a Controller for receiving data from the active DSPX, a Master 1 for providing the drive signal to the Attenuator Module’s sense resistor, and a Master 2 for providing the drive signal to the Attenuator Module’s sense resistor.
  • The front panel of the board is rather big. The IS200EGDMH1A is a two-slot board. The front panel displays the manufacturer’s insignia, the board number, and many warning lights.
  • The board has two backplane connections. Two lines are connected by seven high-voltage capacitors. On the board, there is one relay, one CPU socket, and various integrated circuits.
  • The board is built with metal film resistors as well as resistors made of other materials.
