Product Description
The GE IS200EISBH1A is an Exciter ISBus Board for the EX2100 series excitation control systems.
It provides reliable data transfer between M1, M2, and C control modules in GE system setups.
The unit receives high-speed optical feedback signals from EDCF boards inside the control cabinet.
It sends this critical field data directly to the DSPX digital signal processor via the backplane.
This 3U single-slot module also supports local RS-232C communication for keypad and maintenance software tools.
It integrates built-in ISBus interface circuits to keep triple-redundant exciter systems synchronized.
Engineers fit this card into the main rack right under the primary DSPX controller.

System Compatibility and Integration
- Designed for M1, M2, and C controllers inside EX2100 control racks.
- Hooks up directly to EDCF interface cards using high-speed optical links.
- Connects to the EGDM module for continuous ground fault detection.
- Pairs with the DSPX processor through standard backplane connections.
Front Panel Optical Connectors
- Receives generator field DC voltage signals via fiber cables.
- Accepts generator field DC current inputs from EDCF boards.
- Processes optional exciter DC voltage feedback inputs cleanly.
- Handles optional exciter current inputs without electrical noise.
- Transmits voltage signals directly to the ground detector module.
- Reads voltage feedback outputs returned from the ground detector.
Installation and Diagnostics
Slide the IS200EISBH1A board straight into the 3U rack slot right below the DSPX unit.
Align all fiber optic cables with the six front ports before securing the mounting screws.
Six front LED indicators display live status for field voltage, current, and ground test lines.
These status LEDs allow fast visual checks during routine maintenance and troubleshooting.
Typical Application Scenarios
- Gas turbine generator field excitation control in power plants.
- Steam turbine voltage regulation setups using GE EX2100 racks.
- High-availability redundant exciter hardware upgrades for industrial sites.
