Single Resolver Decoder
Model DM2-STRAK-xxxx
and DS2-STRAK-xxxx
Autotech’s Single Resolver Decoder Model DM2-STRAKxxxx 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 11–28 VDC input power. The
decoder provides complimentary quadrature phase outputs.
·
Decoder for single resolver
·

·
Broken resolver cable indication
·
PNP sourcing, NPN sinking (high or low true logic) or
TTL outputs
·
Short circuit protected outputs and output shorted indicator (only with P & N type of 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.

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.

Notes:
1. Black/Green indicates a black wire with green stripes.
2. MS connector: MS3112E-12-10P; Mating connector: MS3116F-12-10S
(Autotech part # ECM-10REC-ITT).
3. MS connector is not available with E8R series.
Grounding and Shielding
1. Resolver wiring must be done using twisted pairs in cable
with an overall foil shield. The twisted pairs must be wired
as per wiring instructions. See the How to Order section
for suitable cable offered by Autotech.
2. It is recommended that the shielded resolver cable be
routed in its own conduit or cable tray.
3. All shielded resolver cable must be kept at a minimum distance of 2 inches from all high voltage or inductive wiring.
4. All shielded resolver cable must be kept at a minimum distance of 12 inches from all motor wiring controlled by AC
or DC drives.
6. The shield drain wires may be terminated in one of two
ways:
a) Connect to chassis ground at each end and not connected to signal reference at any point in the system.
b) Connect to signal reference at the decoder only. The
shield drain should remain unconnected at the resolver
end and the shield should not touch earth ground at any
point in its run.
NOTE: Resolvers with MS connectors have shield drain
wire pre-terminated for method a).
Method a) is recommended for all Autotech products.
In certain circumstances, in unusual EMI conditions,
method b) may be necessary after consulting factory.
5. All ground planes (chassis grounds) in the total system
must be held to the same RF potential, by good metallic
connections to building frames, conduit or wiring trays.

the unit may directly threaten life or cause human injury. The system should be so designed that a single failure or
malfunction does not create an unsafe condition. Regularly scheduled inspections, at least once a week, should be
made to verify that the redundant circuits are fully functional. All faults should be immediately corrected by repair or
replacement of the faulty unit. In addition, the user may have to comply with OSHA, ANSI, state or local standards of
safety. The user of Autotech Controls' products assumes all risks of such use and indemnifies Autotech Controls
against any damages.
The information in this installation manual has been carefully checked and is believed to be accurate; however, no responsibility is assumed for inaccuracies. Autotech Controls
