| DESCRIPTION
Autotech's Single Resolver Decoder
model DM2-STRAK-xxxxx is a snap track mounted single resolver
decoder especially designed for OEMs. The unit can be
ordered with PNP sourcing, NPN sinking (high or low true logic),
or with TTL type of outputs. It operates from an 11-28 VDC
input power. The decoder provides complimentary quadrature
phase outputs. |
 |
The unit has built-in diagnostics
for broken resolver cable and for shorted outputs ( P and N
outputs only). Two LED indicators provide positive
indication of a properly working unit. The resolver
interface is short circuit proof.

Transparent:
Output data is continuously updated. The data is latched for
100 +/- 10 usec within 30 usec of a transfer input.
PC Handshake: Edge triggered (Low to high as well as
high to low); 30 usec minimum strobe width; the data is stabilized
within 100 usec of any triggering edge, and remains frozen until
next triggering edge comes in.
Slave Systems: Slave units must be used in
conjunction with an Autotech Master Unit. They cannot be
used as stand-alone units. Up to seven slaves may be added
to one master unit. The slave shares the position transducer
with the master. |
