About the IS200EDEXG2B
This IS200EDEXG2B Exciter De-Excitation Board was manufactured for General Electric's EX2100 or EX2100e Excitation Control System Series, as distinguished just above in this IS200EDEXG2B device's basic product description for your research convenience. The EX2100 and EX2100e subseries that this IS200EDEXG2B product may potentially belong to has a set of specific applications in the excitation control system processes specifically within the specified automated drive assembly that it was originally developed for. This IS200EDEXG2B printed circuit board or PCB for short's greater EX2100 or EX2100e Excitation Control System Series must be considered an obsolete General Electric product series as a whole, given its nature as a legacy GE product series whose manufacture was actually discontinued in one of the many years beyond its initial rollout due to a retailer-highlighted full-series functional obsolescence.
Hardware Tips and Specifications
The IS200EDEXG2B board is a De-Excitation board used to dissipate stored energy from the generator field inductances. There are two independent circuits that will fire SCR gating when the anode-to-cathode voltage of the SCR exceeds a certain value or when either of the two control inputs reads true. These two independent circuits are also supplied by two different power supplies. If this model is being used with a large exciter it is extremely important as well as necessary to connect multiple EDEX boards together, one will function as the Master board and the remaining boards will function as Slave boards. When set up in this configuration the signal will be sent to the Master EDEX and then relayed to the slave boards to fire simultaneously. The IS200EDEXG2B board connects to an Exciter Auxiliary I/O Interface Board (EAUX) that will control the de-excitation on the EDEX board by opening a main contactor/breaker in the field circuit, the moment that this contactor/breaker is opened it will immediately set off a de-excitation command.
The IS200EDEXG2B board is also used in the crowbar subsystem and is the primary board in the crowbar system. The crowbar and de-excitation functions are sometimes provided as a combined EDEX module. When you are operating this module the best manual to use would be the part-specific GEI-100466 manual but as it is hard to find at this time, the GEH-6781 EX2100e Excitation Control Users Guide also works well. The EDEXG2B might be mostly obsolete at this time due to no longer being in production but here at AX Control, we do whatever we can to attempt to get this board for you. If you have the board and it just needs repairs our team of specialists is equipped to do so. Generally, this IS200EDEXG2B EX2100 Excitation Control System Series product is not surrounded online by a great wealth of originally-printed instructional manual materials; almost certainly due to this IS200EDEXG2B product's legacy product series attribution as discussed above. With this being true, the IS200EDEXG2B functional product number itself can be identified as a decent source of IS200EDEXG2B Board hardware component and component specification details, as it codes for these qualities through a series of functional naming segments. For example, the IS200EDEXG2B functional product number begins through an inclusion of the dual-functional IS200 series tag indirectly delegating this IS200EDEXG2B products' normal EX2100 series assembly on top of its more typical domestic original manufacture location. Some of the other relevant IS200EDEXG2B Board hardware details revealed in this fashion include its EDEX functional product abbreviation as well as its normal PCB coating style, group 2 EX2100 Series product grouping, and finally its singular B-rated functional product revision.
