Allen-Bradley - Rockwell Automation PLC-5 System

Series Prefix : 1771, 1785

For decades the PLC-5 system was the most popular of the Allen-Bradley - Rockwell Automation PLC lines. Because it was so reliable and versatile, the PLC-5 has survived the test of time. Qualitrol International provides remanufactured and hard-to-find replacement parts for the Allen-Bradley PLC-5 family. Remanufactured PLC-5 parts are a cost-effective alternative to new PLC-5 Parts.

Whether you need 1771 I/O modules, Processors, or Power Supplies and Racks, Qualitrol has the PLC-5 parts needed to keep your system running for years to come. Each of our remanufactured PLC-5 parts comes with our exclusive 2-year warranty - learn more about our quality remanufacturing process in our Why Use Qualitrol section.

We repair any Allen-Bradley PLC-5 part in house with fast turnaround - call our PLC Repair Hotline today at 1-800-784-9385.
