ASY-M8251-010, ASY-MS251-F10 PLS Modules
Power Requirements:
Rack: 5 VDC @ 650 mA
Customer: >24 VDC @ 100 mA
Operating Temperature:
-10°F to +130°F (-23°C to +55°C)
PROGRAMMING:
Number of PLS Setups: 8 Groups
PLS Setpoints:
Front Panel: 160 per PLS setup (80 per group of 8
outputs)
Backplane: 112 per PLS setup (56 per group of 8
outputs)
Scale Factor: Programmable from 16-999, common to all
PLS setups (resolution 17 to 1000 counts-per-turn)
Offset: Programmable from 0 to scale factor value, common
to all PLS setups
Speed Compensation: Programmable in scale factor
units-per-100 rpm, up to full scale factor value. Each PLS
channel has its own speed compensation.
Motion Detector: LOW and HIGH Motion Limits, common
to all PLS setups. Programmable from 0-1999 RPM.
Update Time: (Maximum Speed with 1° Resolution)
Module: Time Speed (RPM)

ASY-M8251-F10: 0.8 ms
200
RESOLVER INTERFACE:
Position Transducer: Single-Turn Resolver, AVG
Automation series RL100, RL101, E7R, E8R, or
equivalent
Resolver Cable: CBL-10T22-xxx
Where xxx = length in ft, 010, 020,050, and 50 ft.
increments, e.g., 100, 150, 200 ft., etc. (3.05,6.1,15.24
and 15.24 m increments, e.g., 30.48,45.72,60.96 m, etc.)
Overall foil shielded, twisted pair
Cable Length between Resolver and M8251: 2500 ft.
(762 m), max.
Maximum Resolver Shaft Speed: 2000 RPM

CONTROL INPUTS:
Electrical Specifications: (All lnputs)
Optical Isolation: 2500 V
Input Impedance: 7500 ohms
Logic Levels:
TRUE: 20-30 VDC; 3 mA @ 24 VDC
FALSE: 0-2 VDC, or open circuit
Program Enable (PE): When TRUE, enables setpoint
programming
Supervisor Enable (SE): When TRUE enables setpoint
and setup (scale factor, offset, program number, etc.)
Output Enable (OE): When TRUE, PLS channel outputs
enabled (both Fault and Motion always enabled)
ModZ and Brake Inputs:
MZ1 /B1 = ModZ input I or Brake Input;
MZ2/BC = ModZ input 1 or Brake Clear;
MZ3 = ModZ Input 3
MZ4 = ModZ Input 4
OUTPUTS:
An output module is required for connection to field
devices. Consult AVG Automation's M8250 Sourcing or
M8250 Sinking Output Module Manual (part
MAN-M8250-POUT and MAN8250-NOUT, respective).
Fault Output: Normally energized; de-energizes if broken
resolver wire or M8251 internal fault is detected.
Motion Output: Output is energized whenever resolver
RPM is between upper and lower programmed motion
limits.
Number of PLS Outputs: 16
