THE DMS The DMS decoders are available with either output or input multiplexing. The resolver analog signals are converted to the output digital format by a tracking resolver-to-digital converter. With input multiplexing, the analog signals are multiplexed to a single digital converter. In output multiplexing, multiple decoders are multiplexed to the parallel digital output port. The binary code at the input selects a particular resolver for output. Output multiplexing allows for a fast response and is recommended for high-speed operations. In the input multiplexing versions, there is a 100 ms settling time after a change in resolver selection before the data is stable. The output multiplexing has only 15 ps settling time. 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 programmable controller. 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 (sourcing)- or NPN (sinking)-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.
