GE IS200EGDMH1AGG Exciter Ground Detector Module
Product Details:
GE IS200EGDMH1AGG is an excitation ground detection module, which belongs to the
EX2100 excitation control series and is manufactured by General
Electric Industrial Systems. The module detects the leakage
resistance between the excitation loop and the ground to identify
potential ground faults and ensure safe operation of the system.
Its notable features include A-level functional revision, G-level
functional revision and G-level appearance revision. It supports
simplex or triple redundant configuration, and three EGDM modules
are used in the triple redundant system. At the same time, it
adopts a double-height double-slot circuit board design, which is
suitable for installation in the control power module of the
control cabinet.
Features:
Sense Resistor: Uses a unity gain differential amplifier with a high common mode
rejection ratio to accurately detect the ground loop.
Analog-to-digital conversion: The conversion of analog signals to digital signals is realized
through a voltage-controlled oscillator (VCO).
Fiber optic transmission: Uses a fiber optic transmitter to communicate with the EISB
option board to ensure signal transmission reliability.
Protective design: The circuit board uses conformal coating technology to fully
cover all component surfaces, providing moisture, corrosion and
vibration protection.
