IS200ESYSH3A Excitation system interface board
IS200ESYSH3A is an excitation system interface board produced by General Electric (GE), which is mainly used to control the excitation system of generators.
The following is a detailed function description of the IS200ESYSH3A:
Excitation control system I/O interface: IS200ESYSH3A board is an I/O terminal board, its function is abbreviated as ESYS, which stands for excitation control system I/O interface. Its main role is to connect the basic inputs and outputs externally to the exciter within the control system.
Interfaces and connections: The board has seven auxiliary contact inputs and is powered by 55 VDC. Most of the EX2100e system I/O interfaces will be processed through the ESYS board. All interfaces provided by the ESYS board will be sent to the EX2100e control system via the included HSLA High Speed Serial Link (HSSL) subboard.
Redundancy mode: The ESYS model has multiple groups H3, H2, and H1, each of which operates in a different redundancy mode. Since the IS200ESYSH3A model is an H3 model, it will operate as a simplex control.
Trip relay outputs: The board has two trip relay outputs, usually these trip relay outputs are used to drive customer locking devices based on two-out-of-three hardware voting outputs.
Multifunctional applications: The IS200ESYSH3A model can be used in both regulator and static systems, rather than one or the other. It can be used not only for the excitation control of generators, but also for the excitation control of power systems and the control of automated production lines.
In summary, the IS200ESYSH3A is a powerful excitation system interface board with a high degree of flexibility and reliability to meet the needs of various industrial automation and control systems.
