Programmable Limit Switches (PLS)

M1050 PLS
THE HIGH-PERFORMANCE SELF-CONTAINED PROGRAMMABLE LIMIT SWITCH
Includes Power Output Relays in the Same Chassis Eight PLS Outputs, Motion Output, and Fault
Output in compact chassis.  No external power relay chassis or customer power supply needed.  (Selected models do no use relay rack, except for expansion greater than 8 outputs.)

• Eight PLS programs can be remotely or keyboard
  selected to simplify job changeover
• Built-in speed compensation for all PLS outputs
• All inputs and outputs fully isolated
• Built-in self diagnostics
• Simple creative keyboard
• Setpoints-per-program
  --8-channel units--80
  --16-channel units--160
• Programmable resolution from 17-1000 divisions-
  per-revolution
• Simultaneous display of program number, channel
  number, ON and OFF setpoints, and output status
• Rugged, reliable, resolver as position transducer, 
  can be mounted up to 2500 ft (762 m) away
• Patented up and down arrow keys for fine-tuning, 
  even with machine in full motion
