About the IS200EDEXG1A
This IS200EDEXG1A Exciter De-Excitation Board printed circuit board product offering from General Electric was, as mentioned in our brief functional product description inserted above, originally designed and produced for placement in the EX2100 Excitation Control System Series. As you have more than likely been able to tell base off of its full extended series name alone, the EX2100 series that this IS200EDEXG1A Exciter De-Excitation Board product offering belongs to has specific applications pertaining to excitation control system processes specifically. This IS200EDEXG1A printed circuit board product offering is actually not considered the originally-developed product of its specific EX2100 Excitation Control System Series functional role, as that would have to be considered the IS200EDEXG1 parent Exciter De-Excitation Board not making any use of this IS200EDEXG1A device's sole A-rated functional product revision.
Hardware Tips and Specifications
The IS200EDEXG1A model is a De-Excitation module that is primarily used to function as a bridge and protection board. The prime purpose of this board is to store energy that has been provided to the generator, the energy that has been provided to the generator must be dissipated upon shutdown. It is important when operating this board that you note that the IS200EDEXG1A board is typically controlled by the EXTB. This module provides conduction sensing feedback, plus voltage retention which will ensure that the board can still operate in case a power-failure event occurs and allows for SCR de-excitation firing. When two of the control inputs reads as true or the anode to cathode voltage related to the SCR exceeds a certain value that is when the SCR de-excitation will fire. Apparently, two versions of this IS200EDEXG1A product are currently being offered online for purchase and repair; the group one-grouped EDEX boards are considered applicable to SCR de-excitation processes specifically, with the group two-grouped boards pertaining to diode de-excitation processes more specifically. This IS200EDEXG1A device benefits from its original General Electric product manufacture, given the fact that its IS200EDEXG1A functional product number itself stands to outline a number of relevant IS200EDEXG1A Board hardware details, including this IS200EDEXG1A device's:
- EDEX functional product abbreviation
- Normal PCB coating style
- Group one EX2100 Series product grouping
- A-rated primary functional product revision
This board comes equipped with Hall effect conduction sensors which will sense the magnetic field produced by field current discharge that flows through the thyristor. The IS200EDEXG1A board receives power from the ESPM module, the power that should be received from that module should be 24 VDC; the EDEX module will then turn the power received into 125 VDC. This IS200EDEXG1A Exciter De-Excitation Board product should in theory exist as a well voltage-protected EX2100 Excitation Control System Series product, given the fact that its base printed circuit board is rather obviously jam-packed with over ten total electrolytic drum-style capacitor components; a staple of a larger EX2100 series voltage limitation strategy involving various other types of IS200EDEXG1A Exciter De-Excitation Board voltage-limiting hardware components including but not limited to different resistors, transistors, diodes, and specialized integrated circuits or ICs. According to the various IS200EDEXG1A Exciter De-Excitation Board instructional manual materials made available to our convenient manuals tab above, this IS200EDEXG1A Exciter De-Excitation Board product exists as the central component product to the greater EX2100 Series' de-excitation module, as it specifically provides this module with de-excitation firing of silicon-controlled rectifiers and conduction sense feedback reporting as well as an additional failsafe layer of voltage protection. This IS200EDEXG1A Exciter De-Excitation Board is but one of many General Electric EX2100 or EX2100e Series exciter bridge and protection products, which include different devices ranging from the similarly-named IS200EXAM Exciter Attenuation Module to the more simply-described crowbar module. At least the former of these two offerings is available in a number of different revision versions for both repair and replacement here today.
