Functional Description

IS200ESYSH3A is an I/O terminal board developed by GE. The model is a simplex control that is part of

General Electric’s EX2100e series. Isolation transformers are used in this model. The model has seven auxiliary

contact inputs and a 55 VDC power supply. The interface board is used with generator voltage PTs and CTS

required for protection functions. The board accepts external I/O and outputs transducers. It is intended to

handle all input and output interfacing requirements. PT and CT inputs, general-purpose and trip relay outputs,

analog inputs and outputs, and digital control inputs are all included. These interfaces take place via terminal

boards mounted on the ESYS board via terminal strips that provide terminal connections. Typically, these

daughter boards are HSSL or HSLA boards.

Features

• This board’s functional acronym is ESYS, which stands for Excitation Control System I/O Interface. This board’s
• primary function is to connect the basic input and output to the exciter within the control system. The board will
• handle the majority of the EX2100e system I/O interfaces. The interfaces will be sent to the EX2100e control
• system via the attached HSLA high-speed serial link (HSSL) daughterboard.
• The model is divided into three groups: H3, H2, and H1, each with its own redundancy mode. Because the
• model is an H3, it will function as a simplex control.
• Apart from having different redundancy modes and fewer control sections than the other groups, these boards
• operate in the same way, for example, by supporting excitation contact outputs and inputs. The board can handle
• CT and PT inputs; there are two generator CT inputs with current ratings of 1 A or 5 A that provide current
• feedback; and two three-phase generator PT voltage inputs that can be connected together for generator voltage feedback.
• The board has two trip relay outputs, which are typically used to drive a customer lockout device with two-of-three
• hardware voting outputs. This model can be used in both regulator and static systems, rather than just one of them.
