FUNCTIONAL DESCRIPTION:
IS200EXIBG1AAA is an Exciter Bridge Interface Module manufactured and designed by General Electric as part of the EX2100 Series used in GE Excitation Control Systems. It serves as the interface between the control electronics and the exciter power bridge. It manages the transmission of firing signals to the bridge and continuously monitors voltage, current, and bridge status to ensure reliable excitation control. The module also provides electrical isolation between high- and low-voltage circuits, protecting sensitive components and improving overall system stability. Built with robust fault detection and diagnostic capabilities, it ensures safe and precise generator operation under all load conditions.
INSTALLATION:
The module is designed for secure mounting within the Mark VI Excitation Control Cabinet. Connections are made via multi-pin connectors to interface with other excitation system boards. During installation, proper grounding and alignment must be ensured, and the environment should be free from excessive heat, dust, and moisture. Handling should follow standard ESD precautions to prevent damage to internal circuitry. After installation, initial configuration and testing should be performed through the control system to verify communication and operational readiness.
OPERATION:
The EXIB module transmits firing commands from the controller to the power bridge while receiving continuous feedback on current, voltage, and bridge health. It detects abnormal conditions such as overcurrent, voltage irregularities, or feedback loss, and reports these to the control processor for immediate corrective action. By maintaining accurate communication between the control electronics and the exciter bridge, the module ensures stable voltage regulation, smooth generator performance, and reliable system protection.
