Shipping & Payment

The GE IS200EISBH1A is an Exciter ISBus Board designed for the GE EX2100 excitation control system. It provides a communication interface within the control rack and is identified by the functional abbreviation EISB. The board is a 3U-format assembly installed beneath the DSPX board, with six front-panel indicators for monitoring generator field and exciter voltage and current, as well as ground detection input and output status.

Functional Role and Signal Communication

The EISB board provides the interface between the EX2100 controller electronics and the excitation system's feedback and ground detection circuits. In redundant configurations, its ISBus interface electronics support data exchange among the M1, M2, and C controllers.

The front panel provides six fiber-optic connections for variable-frequency signals:

Generator field DC voltage feedback.
Generator field DC current feedback.
Exciter voltage feedback (optional).
Exciter current feedback (optional).
Ground detector voltage input.
Ground detector voltage output.

The feedback signals are transferred through the associated EDCF interfaces. The optional exciter voltage and current connections depend on the system configuration. The EISB also exchanges controller data through the control backplane.

Front-Panel Indicators

Six indicators provide status information for the following signal groups:

Generator field voltage and current.
Exciter voltage and current.
Ground detection input and output.

These indicators help maintenance personnel distinguish feedback and ground detection signal status during troubleshooting. They should not be interpreted as six independent analog measurement channels.

Installation and Configuration Notes

The IS200EISBH1A occupies a single 3U slot in the EX2100 control rack and is associated with the DSPX controller. Its six fiber-optic connections provide dedicated paths for feedback and ground detection signals.

Before replacing the board, verify the complete catalog number, including the H1A suffix. The EX2100 board identification convention distinguishes functional revisions and assembly variations, so similar EISB part numbers should not automatically be treated as interchangeable.
