Compatibility & Replacements
The 20AC3P5A0AYNANNN was discontinued by the manufacturer on January 20, 2010, and is classified as surplus/used stock. It integrates with Allen-Bradley control systems and Logix platforms via standard industrial networking. Equivalent or successor models in the PowerFlex family should be confirmed with Rockwell Automation for new installations. This unit is a direct replacement for identical part numbers (20AC3P5A0AYNANNN/A is an alternate designation). As a used Series A component, firmware and configuration may require review before deployment in critical systems. Contact technical support or your systems integrator for compatibility verification with your specific PLC and control architecture.
