Allen-Bradley - Rockwell Automation SLC 500 System

Series Prefix : 1746, 1747

With hundreds of thousands of installed systems worldwide, the Allen-Bradley - Rockwell Automation SLC 500 system is the center of many industrial PLC applications. Hundreds of I/O and processor options make this one of the most versatile PLC platforms in the industry.

Qualitrol International provides quality remanufactured Allen-Bradley / Rockwell Automation SLC 500 parts, including 1746 I/O modules, 1747 Processors and Intelligent modules, and all of the racks and power supplies to complete your SLC 500 system.

Remanufactured SLC 500 parts from Qualitrol are a smart and cost-effective alternative to new. Each of SLC 500 parts undergoes our quality testing and assurance process to guarantee that the SLC 500 part you buy from Qualitrol works the first time and works for years to come. Learn more about our remanufacturing process that set us apart from everyday surplus SLC 500 parts providers.

We also repair any Allen-Bradley SLC 500 part in house with fast turnaround - call our PLC Repair Hotline today at 1-800-784-9385 or email us at repairs@qualitrol.com.
