SDC-14560
DESCRIPTION
The SDC-14560 is a series of high-reli-
ability synchro or resolver-to-digital con-
verters with user-programmable resolu-
tion of 10, 12, 14, or 16 bits. Other fea-
tures of the SDC-14560 are high-quali-
ty velocity output and hermetic seal.
User-programmable resolution has
been designed into the SDC-14560 to
increase the capabilities of modern
motion control systems. The precise
positioning attained at 16-bit resolu-
tion and fast tracking of a 10-bit
device are now available from one 36-
pin double DIP hybrid. Velocity output
(VEL) from the SDC-14560 is a
ground-based
voltage
of
0
to
±10 VDC with a linearity to 0.7%.
Output voltage is positive for an
increasing angle.
The
SDC-14560
series
accepts
broadband inputs: 360 Hz to 1 kHz, or
47 Hz to 1 kHz. The digital angle out-
put from the SDC-14560 is a natural
binary code, parallel positive logic
and
is
TTL/CMOS
compatible.
Synchronization to a computer is
accomplished via a converter busy
(CB) and an inhibit (INH) input.
APPLICATIONS
Because of its high reliability, accura-
cy, small size, and low power con-
sumption, the SDC-14560 is ideal for
the most stringent and severe indus-
trial and military ground or avionics
applications. All models are available
with MIL-PRF-38534 processing as a
standard option.
Designed with three-state output, the
SDC-14560 is especially well suited
for use with computer-based systems.
Among the many possible applica-
tions are radar and navigation sys-
tems, fire control systems, flight
instrumentation, and flight trainers or
simulators.
