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.
