The IS200EPCTG1AAA is a component manufactured by General Electric for its Mark VI Speedtronic system, tailored for the control of industrial gas/steam turbines.
Speedtronic Line
The Speedtronic line originated with the Mark I in the late 1960s and has since seen iterative enhancements with each subsequent release. The Mark VI, the latest iteration, introduces Ethernet capability, a PC-based operator interface, and proprietary software like CIMPLICITY and GE Toolbox, enhancing system functionality and user experience.
Functionality
The IS200EPCTG1AAA serves as an Exciter PT/CT board, featuring two three-phase inputs for generator PT voltage, two current inputs for generator CT voltage, and a single analog input.
Physical Design
The board is characterized by three terminal strips along its front edge: a single 24-position strip and two 4-position strips. At the rear edge, three vertical pin connectors labeled J315, J305, and J308 are present. Additionally, the board includes 12 test points, a jumper switch, 2 toroidal transformers, 4 transformers mounted in frames, as well as resistors, capacitors, and metal oxide varistors (MOVs).
