Product Description

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.
