DMS - Advanced Features

Variety of Outputs, Built-in PC-Handshake permit Interface to any PLC

BCD, natural Binary, or Gray Code output formats are available with a choice of TTL, PNP (sourcing) transistor, or NPN (sinking) transistor outputs. Optional PLC synchronization circuit provides an error-free method of interfacing output position data from the decoder to any PLC. Upon receipt of a data transfer command from the PLC, the stable data is latched and made available to the PLC.

Multiplexing Capability

The TTL- type of outputs have multiplexing capability, which allows more than one decoder to be connected to the same control unit for multi-axis applications. For multiplexing PNP- or NPN-type outputs, consult the factory.

Up to 4096 Counts-per-Turn Resolution at 1800 RPM

The DMS series resolver decoders are available with resolutions ranging from 256 to 4096 counts-per-turn to match unlimited control needs. The high-performance ratiometric-tracking converter assures exacting performance at speed up to 1800 rpm.

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 tempera-ture 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 rugged-ness of a resolver and reliability of an advanced solid-state con-trol. The rugged, heavy-duty NEMA 13 (IP54) resolver can be ounted on a machine shaft in any hostile industrial environ-ment, such as mechanical shock, vibrations, extreme humidity and temperature changes, oil mists, coolants, solvents, etc. The DMM decoder can be mounted up to 2500 ft (762 m) from the resolver in a control panel.
