Synchros are transformer-type voltage/current transducers that convert a shaft or other rotating device's angular position and/or velocity to a multi-wire AC electrical signal. Both deliver signals proportional to the Sine and/or Cosine of the shaft angle. A Digital-to-Synchro simulator is used to convert digital angle/velocity commands to corresponding Synchro/Resolver AC signals.

Angle Indicators
Computer Conversions Corporation
This series of units were designed to satisfy Hi speed multiturn synchro/resolver applications where the output data must be fresh and no data staleness can be tolerated. The tranducers utilized are the same as in the regular MDS series, however different tracking electronics are used. The resultant data tracks the input shaft perfectly and is always fresh and accurate at input speeds up to 64 revolutions per second, depending on the resolution. Data in BCD or Binary formats are available, and clean, unambiguous crossovers are guaranteed.
