Product Overview
The IS200EXAMG1A is a specialized Exciter Attenuator Module (EXAM) engineered for the GE EX2100 Excitation Control system. This module is critical for generator protection, acting as a bridge and monitoring interface that applies a low-frequency AC signal to the field windings for ground fault detection. By working in conjunction with the EGDM module, the IS200EXAMG1A facilitates the identification of insulation degradation or leakage currents, enabling proactive maintenance strategies that prevent potential generator damage and unplanned outages in power generation and heavy industrial environments.
Features
- Designed for integration within the EX2100 Excitation Control architecture.
- Supports high-reliability redundant operation via M1 and M2 controller switching.
- Features precision sensing circuitry to monitor field ground leakage.
- Configurable signal attenuation and bridge logic via onboard jumpers (JP1, JP2, JP3).
- Robust physical interface including dedicated ground detector cabling and high-current stab-on connectors (Vbus-p/Vbus-n).

Installation Guidelines
- Ensure all power is disconnected from the excitation system before installing or removing the module.
- The module is typically installed within the auxiliary cabinet of the EX2100 system.
- Ensure all cabling, including the 9-position ground detector connector and high-current E1/E2 stab-on connectors, is properly seated and secured to prevent intermittent faults.
- Verify jumper settings (JP1, JP2, JP3) match the site-specific configuration requirements before commissioning.
- Handle with standard ESD precautions to protect sensitive onboard components.
FAQ
What is the primary function of the IS200EXAMG1A?
It acts as an attenuator and bridge module that injects a low-frequency AC test signal into the field winding to detect potential ground faults in the excitation system.
Does this module support redundant control systems?
Yes, the IS200EXAMG1A is designed to support redundancy, allowing for seamless switching between M1 and M2 controllers.
Which module does the EXAM interface with for measurements?
The EXAM module transmits control and sense signals to the EGDM module, which performs the final analysis and measurement of field leakage currents.
