DMS MULTI-AXIS SINGLE-TURN RESOLVER DECODERS
 

Highly Noise Immune Circuitry
The ratiometric tracking converter technique employed for resolver-to-digital decoding provides the best protection against electrical noise generated by power line transients, radio frequency interference, and varying ground potentials. The ratiometric converter is practically immune to temperature variations and line frequency changes. Optional optical isolation adds another layer of protection and enhances system integrity.

Extremely Rugged and Reliable Resolver As Position Transducer 
The DMS series of resolver decoders combines the ruggedness of a resolver and reliability of an advanced solid-state control. The rugged heavy-duty NEMA 13 UP54) resolver can be mounted on a machine shaft in any hostile industrial environment, such as mechanical shock, vibrations, extreme humidity and temperature changes, oil mists, coolants, solvents, etc. The DMS decoder can be mounted up to 2500 ft (762 m) from the resolver in a control panel.
