RDE
Most closed-loop motors controllers require the incremental quadrature feedback that encoders provide. Empire Magnetics’ RDE resolver-to-digital converter module closes the loop betwen rugged feedback resolvers and motor controllers that require encoder feedback.
RDE converters connect easily to Empire Magnetics resolvers, providing complementary TTL compatible two phase quadrature and outputs with index (Channels A, B, and Z).
For a more detailed look at the specifications, consult the RDE Manual.
