PC104 Synchro/Resolver Simulation Board

Discontinued Product.  Documents below are still available for download.

NAI’s 73DS2 is a PC104-compatible Synchro/Resolver Simulation Board with three isolated channels. These channels can incorporate up to three Digital-to-Synchro/Resolver Converters with 1.2 VA drive capability in a stack-through module. With galvanic isolation, one of the outputs can be grounded without affecting performance.

Standard features include continuous Background Built-In-Test (BIT), and reference and signal loss detection. Major diagnostic capabilities, including malfunction alerts and a choice of either an on-line test or an off-line test, provide substantial improvements to system reliability. Specifically designed for rugged defense, commercial aerospace, and industrial applications, the 73DS2 supports an optional 3 VA reference supply and drives passive loads. Requires forced air cooling.
