Siemens 6ES7511-1CL03-0AB0 SIMATIC S7-1500 CPU 1511C-1 PN 300KB/1.5MB Programmable Logic Controller

The Siemens 6ES7511-1CL03-0AB0 is a SIMATIC S7-1500 compact CPU 1511C-1 PN with 300 KB of program memory and 1.5 MB of data memory, plus onboard 16 digital inputs, 16 digital outputs, 5 analog inputs and 2 analog outputs. Its PROFINET IRT interface includes a 2-port switch and processes bit operations in 6 ns, and it requires a SIMATIC Memory Card to run.

Technical Specifications

Selection Notes

The compact (C) CPU integrates discrete and analog I/O plus 6 high-speed counters directly on the module, removing the need for a separate signal module in a small or mid-size machine; pick a non-compact CPU such as a plain 1511-1 PN instead when the application needs more distributed I/O or additional communication module slots, since onboard I/O is fixed and cannot be resized. The 4 integrated PTO/PWM channels support direct stepper or servo pulse-train control without adding a positioning module.

Applications

Standalone or single-cell machine control that needs integrated discrete and analog I/O together with pulse-train axis control (PTO/PWM) and PROFINET IRT connectivity to distributed I/O or drives, without a separate signal module.
