PLC Replacement of Relay Controls & New Custom Enclosure

OVERVIEW

Simplify your conglomeration of relays and switches and make operations more efficient with a programmable logic controller (PLC).

In this application, paper used in the medical profession is rolled using a multi-spindle, high-speed paper winder that automatically winds the correct length of paper, then transfers it to the next roller on-the-fly. Paper length for the roll is predetermined and based on a selector switch. When the spindle completes its winding procedure, the operator unloads the completed roll, loads a bare, cardboard tube on the empty spindle and the process repeats.

Running the main winder is a 50 HP DC drive that is reused in the new system. The old system of relays was replaced with a programmable logic controller (PLC). An existing programmable limit switch is now interfaced to the PLC. A new operator station completes the system.
