| DESCRIPTION
Autotech's Dual Resolver Decoder
model DM2-DTRAK-0X is a snap track mounted dual resolver decoder
especially designed for OEMs. The unit can be ordered with
PNP sourcing, NPN sinking, or with TTL type of outputs and
operates from an 11-28 VDC input power. The standard unit
supports gear ratios of 16:1, 32:1, 64:1, and 128:1 between fine
and coarse resolvers. The decoder provides BCD, Binary or
Gray code outputs. the outputs are updated |
 |
transparently or by an external
data transfer input. The gear ratio, output code and the
output update method are field selectable by dip switches.
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. |

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.
Data Transfer Input: 10-28 VDC input |
