I/O modules

The GE  IS200EXAMG1A serves as a critical bridge and protection module for generator excitation systems. This Exciter Attenuator Module drives the field winding’s electrical center with low-frequency AC voltage. It primarily works to detect potentially dangerous field ground leakage currents within the system.

Core Function and Integration

The IS200EXAMG1A module collaborates directly with the EGDM (Exciter Ground Detection Module). It specializes in detecting field ground leakages during operation. Subsequently, the connected EGDM module measures these leakage currents precisely. This team ensures reliable protection for the generator’s field circuit.

Physical Layout and Connector Details

This module features a clear and functional board layout for easy integration. It includes two key female connectors: a three-position plug and a nine-position cable port. The cable connector is specifically labeled as the ground detector for clear identification. Furthermore, the board provides a single-screw terminal for secure surface wiring connections.

Key Components and System Redundancy

Important stab-on connectors on the board are labeled Vbus-p (E1) and Vbus-n (E2). The module also contains three configurable jumpers at positions JP1, JP2, and JP3. For use in redundant systems, a switch selects between M1 or M2 controller test signals. This design enhances system reliability and allows for flexible configuration.
