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 indica-
tors provide positive indication of a properly working unit.
The resolver interface is short circuit proof.

Position Transducer: AVG Automation's single turn resolver
such as RL100, RL101, RL500, RL501, E1R, E7R, E8R, or E9R
series

Output Formats: Factory scale quadrature
Output Type:
P: PNP sourcing:
Logic TRUE:
Transistor ON, 1.7 V drop @ 100 mA
Logic FALSE: Transistor OFF, 0.2 mA leakage @ 50 VDC
N: NPN sinking (LOW TRUE LOGIC):
Logic TRUE:
Transistor ON, 1.1 V max. @ 100 mA
Logic FALSE: Collector open, 0.1 mA leakage @ 50 VDC
C: NPN sinking (HIGH TRUE LOGIC):
Logic TRUE:
Collector open, 0.1 mA leakage @ 50 VDC
Logic FALSE: 1.1 V drop @ 100 mA
T: TTL output, 5V logic with multiplexing:
Logic TRUE:
3.00 mA max, 2V min.
Logic FALSE: 24.0 mA max, 0.8V max
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-along
units. Up to seven slaves may be added to one master unit.
The slave shares the position transducer with the master.
