PLS-601 - Full Featured Programmable Limit Switch
A programmable limit switch is a device which overcomes the shortcomings of mechanical cam
switches by performing the cam functions electronically rather than mechanically. Instead of
having to physically adjust the timing and dwell of a number of mechanical cams, the
programmable limit switch (PLS) allows a user to enter the timing and dwell settings via a
keyboard. The timing and dwell settings are then stored in a solid state memory and used to
control whether the outputs of the electronic switches are turned ON or OFF.
The PLS-601 provides one source for all of your programmable limit switch actions at
your machine. It is used to control automated functions during a machine cycle.
This product will eliminate the time it takes to manually adjust mechanical limit
switches.
The front panel utilizes an alpha numeric display, 3-mode keyswitch and keyboard. Status LEDs
for channel output and motion detect, combined with other features, gives this product
unparalleled functionality.
