IS200ESYSH3A Control excitation system
IS200ESYSH3A is a product produced by General Electric (GE), which is mainly used to control excitation systems, and can be used in generator excitation control, power systems and other fields. It is an I/O terminal board with an isolated transformer capable of connecting the basic input and output externally to the exciter within the control system. The board’s function is abbreviated ESYS, which stands for excitation control system I/O interface. The IS200ESYSH3A model has seven auxiliary contact inputs powered by 55 VDC, and also offers multiple interfaces to handle CT and PT inputs, as well as the ability to handle excitation contact outputs and inputs. In addition, it can be used in regulators and static systems.
