CompactLogix 5390: A Scalable Foundation for Smarter Machine Control

8/28/2026

Machines are being engineered with more intuitive and complex capabilities, which can require a more complicated control architecture behind them. Machine builders are being asked to integrate additional controllers, I/O, communications, and safety functions which can increase wiring demands, potential failure points, and difficulties when troubleshooting.

The Allen-Bradley® CompactLogix® 5390 Controller from Rockwell Automation® is designed to help address this challenge. This controller combines high-performance control, integrated safety, and cybersecurity capabilities within a simplified control architecture. Leveraging a modular machine design and common control architecture gives your applications a scalable foundation that is easier to deploy, operate, and maintain.
