Page 2: Model 75Ds2
Description The 75DS2 is a 3U cPCI board which incorporates up to 4 Digital-to-Synchro/Resolver converters with 1.5, 2.2 or 3 VA drive capability; or 2 or 4 isolated DLV converters. The board features continuous background BIT testing, reference and signal loss detection. Each channel is independent, isolated and enables the user to ground one of the outputs without affecting performance. -
