6ES7511-1AL03-0AB0 CPU 1511-1 PN 300KB/1.5MB PROFINET IRT | Siemens

The Original New Siemens 6ES7511-1AL03-0AB0 is a SIMATIC S7-1500 standard CPU 1511-1 PN, designed for mid-range machine automation and industrial control applications. It provides 300 KB of work memory for program and 1.5 MB for data, with a 6 ns bit-operation processing speed for deterministic control. The integrated PROFINET IRT interface with a 2-port switch supports isochronous real-time communication, and the onboard 3.45 cm display with 8 function keys enables local diagnostics and commissioning without additional engineering tools. A SIMATIC Memory Card is required for operation, supporting up to 32 GB load memory.

Core Engineering Highlights:
300 KB program work memory / 1.5 MB data work memory | 6 ns bit operation / 7 ns word operation | PROFINET IRT with 2-port switch | Isochronous mode (500 µs distributed / 1 ms central) | 3.45 cm display with 8 keys + 2 mode buttons | 24 V DC (19.2–28.8 V DC) | 0.56 A rated / 0.9 A max current | 3.4 W typical power loss | 35 × 147 × 129 mm | SIMATIC Memory Card required
