The 73DS2 is a PC/104 compliant stack through module which incorporates up to three isolated Digital-to-Synchro/Resolver converters with 1.2 VA drive capability. This card features continuous background BIT testing, Reference and Signal loss detection and an optional Reference Supply (3 VA). Galvanic isolation enables the user to ground one of the outputs without affecting performance. This model drives passive loads. Major diagnostic capabilities offer substantial improvements to system reliability because user is immediately alerted to malfunctions. See Programming Instructions for further details. Two different tests (one on-line and one off-line) can be selected.
