- Mark VIe series GE Energy IS200 Normal Assembly
- Mark VI IS200 Series produced by General Electric
This board is primarily used to monitor key electrical parameters in the generator excitation circuit, providing precise sampling feedback, particularly for critical indicators such as excitation current, voltage, and grounding detection. It is a crucial component of the closed-loop regulation of the excitation control system, providing real-time power bridge operating status data to the controller and ensuring stable output from the generator excitation system.
In terms of functionality, this module possesses advanced signal processing and protection monitoring capabilities. It integrates a high-voltage isolation circuit, safely processing high-level signals from the excitation power cabinet and converting them into low-voltage signals recognizable by the control system.
The IS200EXAMG1AAB GENERAL ELECTRIC Exciter Attenuation Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The IS200EXAMG1AAB acquires analog signals from the excitation circuit via a front-end shunt or transformer. The onboard signal conditioning circuit first filters and scales these raw signals, then digitizes them through a high-resolution analog-to-digital conversion process. The processed data is transmitted to the control processor via a dedicated VME bus or backplane interface. The processor calculates and adjusts the trigger pulses based on these feedback values, thereby achieving precise closed-loop control of the exciter output.
- Excitation Grounding Detection: Its most critical function is to work in conjunction with the exciter grounding detection module (IS200EGDM) to build a grounding detection system for the EX2100 exciter controller.
- Voltage Scaling and Attenuation: It can detect high voltages from the excitation bridge and scale them down to a controllable level for processing by low-voltage diagnostic modules such as the EGDM.
- Excitation Current/Voltage Feedback: This board provides necessary feedback signals (typically ±50V low-frequency square wave) to the control section to monitor the operating status of the generator excitation winding.
