M8350 RESOLVER DECODER
BusMODULE
SPECIFICATIONS
A complete functional Decoder consists of a Cradle (specific to the programmable controller type), a Decoder Module (ASY-M8350-01 0), and a Filler Module (ASY-M8250-FIL). If fault and/or motion outputs need to be directly wired to field devices, an output module (such as, ASY-M8250-XOUT) must be used in place of the filler module. Consult Autotech for specifications on output module.
Card Location: Uses one or two slots (any location) in an
1/0 rack.
PLC Communication: Command-based communication
using standard program controller logic.
Power Requirements:
Backplane: 5 VDC @ 650mA
Customer (Input Power): 24 VDC ± 100mA
Environment Conditions:
Operating Temperature: -10°F to +130ºF (-23ºC to
+55ºC)
Relative Humidity: 5 to 95% non-condensing
RESOLVER INTERFACE:
Position Transducer: Autotech's series RL 100, E7R,
E8R, or RLI 01, RL500 or equivalent resolvers.
Cable Length between Resolver and M8350: 2500 feet
max, shielded.
Resolver Cable: Overall foil shielded, twisted pair, such as
Autotech's cable (CBL-1 OT22-xxxx).
PROGRAMMING:
All features programmable from keypad or through
backplane.
Scale Factor: Programmable from 19 to 4095 (Resolution
20-4096 counts per turn).

 |
Offset: Programmable from 0 to scale factor value.
OUTPUTS:
RPM Format: Binary
Fault Detector: -TRUE (active) on power-up -FALSE if
broken resolver wire or internal fault is detected.
Motion Detector: -Low and high motion limits are
programmable from 0 to 1999 RPM -motion detector is
TRUE when the machine's RPM is within the
programmed limits motion detector's status is available
on the backplane.
Direction: CW (clockwise) or CCW (counterclockwise)
indication. On is CCW, Off is CW.
RESPONSE TIMES:
Tach Update Time: 15ms
Position, Tach and Output Status available to
Backplane: Every 700 ps typical
CONTROL INPUTS:
Program Enable (PE): PE must be TRUE for
programming.
ELECTRICAL SPECIFICATIONS:
Optical Isolation: 2500 VAC RMS
Input Current: 3 mA typical @ 24 VDC
Logic Levels: -TRUE: 21 to 27 VDC (not to exceed V+
relative to V-) -FALSE:< 1 VDC
