6ES7511-1AK02-0AB0 CPU 1511-1 PN 150KB 60ns PROFINET | Siemens

The Original New Siemens 6ES7511-1AK02-0AB0 SIMATIC S7-1500 CPU 1511-1 PN is a central processing unit designed for medium-scale automation applications requiring balanced performance and connectivity. Featuring 150 KB work memory for program and 1 MB for data, this CPU delivers 60 ns bit-processing speed and a PROFINET IRT interface with integrated 2-port switch. As part of the S7-1500 Advanced Controller family, it sets new standards in system performance and usability. The CPU can be used as a PROFINET IO controller or as a distributed intelligent device (PROFINET intelligent device). A SIMATIC Memory Card is required for operation.

⚠️ Important Product Status Note:

This product has been officially discontinued by Siemens as of May 1, 2024 and will be available only in limited quantities until the final discontinuation date of October 1, 2025. The recommended replacement is the CPU 1511-1 PN (6ES7511-1AL03-0AB0) which offers doubled memory and improved performance. For new designs, customers are encouraged to consider the replacement model.
