About the IS200EBRGH2A

Bridge and Protection module IS200EBRGH2A is a Bridge Interface that is used for controlling related bridge I/O terminal boards as well as controlling the power bridge (SCR). This board is part of the second group of the EBRG boards, this second group is used with thyristors that are seventy-seven millimeters or smaller. One feature of this board is that it can be used with most SCR devices within the EX2100e series, as such, it allows for uses with several bridge architectures and SCR ratings which includes paralleling bridge converters, simplex, and WBU.
