Specifications

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 convert-
er. 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 multi-
plexing versions, there is a 100 ms settling time after a change
in resolver selection before the data is stable. The output mul-
tiplexing has only 15 µs settling time.
Variety of Outputs, Built-in PC-Handshake
Permit Interface to Any PLC
BCD, natural Binary, or Gray Code output formats are avail-
able 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 con-
troller. 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 resolu-
tions 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.
