Rockwell Automation has introduced the CompactLogix 5390 programmable controller, bringing local PointMax input and output modules, integrated safety and cybersecurity capabilities into its Logix product family. Rockwell states that the controller’s physical footprint is 43% smaller than that of the CompactLogix 5380. Its published product information lists commercial availability during the fourth quarter of 2026.
The controller is intended for machine builders, system integrators and industrial users developing automated equipment and production systems. Local PointMax I/O connects control logic with nearby sensor inputs and output devices, allowing an installation to be configured with the modules needed for a particular machine. The controller also operates within Rockwell’s wider architecture for drives, motion control and industrial networking.
The claimed 43% reduction applies to the controller itself, rather than a completed control cabinet. Electrical panels also need space for supplies, protection equipment, terminal blocks and wiring, so the overall cabinet dimensions will depend on the rest of the design. The smaller controller nevertheless provides a defined component dimension when machinery designers lay out control hardware.
Rockwell’s specification lists user-memory options from 400KB to 10MB, with separate listed safety-memory capacity. A USB-C service port is provided, while module and sensor-actuator power connections are specified for 10–30V DC supplies. The published installation requirements include one inch of clearance on all sides and screw or spring terminal-block options. These details are relevant to selecting the controller and configuring its panel connections.
Cybersecurity functions are described by Rockwell as aligned with IEC 62443-4-2, the standard covering technical security requirements for industrial automation components. The manufacturer also cites readiness for the EU Cyber Resilience Act. Those statements should not be read as a certification of every machine or network incorporating the controller; security also depends on system configuration and operation.
Integrated safety allows safety-related logic to form part of the control platform. A complete protective function still includes the relevant sensor and final actuation equipment, with its performance determined by the design and validation of the complete circuit. The product announcement does not give a universal safety rating for every potential application.
The 5390 is designed to integrate with PointMax I/O, Kinetix motion systems, PowerFlex drives, Stratix networking equipment and FactoryTalk Design Studio. Rockwell has not supplied independently measured improvements in machine cycle times or commissioning labour, so the established changes are the controller’s published architecture, dimensions and supported interfaces.
