PL-1746 Series

PLµS® Plug-In Modules for the Allen-Bradley SLC-500 PLC

PL-1746-C01

The PLµS PL-1746 Series Plug-In Modules for Allen-

Bradley PLC’s, incorporate advanced PLS functions in
a 1746 I/O module package.

The PLµS Plug-In Modules provide 12 bit absolute po­sition, and accurate control of functions at high speeds,
based on rotary position input. They complement the
control capabilities of the PLC by performing tasks that
typically must occur much faster than a normal PLC scan
cycle.

In addition to providing precise control of events based
on rotary position, these modules incorporate high speed
control logic and automatic speed compensation, inde­pendent of the PLC scan. Output Groups and High
Speed Logic Modes move beyond standard PLS func­tionality to give the user powerful tools that solve con­trol problems accurately and at high speeds.

Programming of the PL-1746 modules may be done
through the backplane or through the Electro Cam Corp.
model 6400 keypad/display.

PL-1746-C01 Plug-In Module

■ Up to 32 PLS output channels avail-

able through 1746 backplane. All
channels are available to use either
with the Electro Cam Corp. I/O rack
(High Speed/Real World), or any 1746
discrete output module.

■ Real world, high speed I/O available

via either an 8 input/8 output, or an 8
input/16 output external DIN mount
rack.

The PS-4108-13-L08 and PS-4108-13-L16 I/O racks
provide inputs, analog outputs, and digital power
outputs (requiring SLIMLINE™ solid state relays) for
the PL-1746-C01 PLµS plug-in modules.

■ Up to 32 digital plus 2 analog outputs

available.

Resolvers

Electro Cam Corp. Resolvers are de­signed for rugged industrial applications.
They feature dual bearing construction
(except the 5212 model), and come in a
variety of mounting styles and shaft
sizes. Some resolver configurations are
shown here.

See Price List (Lit. #202) for complete
listing of part numbers and specifica­tions.
