Product description
The Siemens 6ES7511-1CK01-0AB0 is a compact central processing unit in the SIMATIC S7-1500 family. Siemens identifies it as the CPU 1511C-1 PN with integrated inputs and outputs. The unit provides 175 KB of program work memory and 1 MB of data memory. It includes 16 digital inputs and 16 digital outputs, supplemented by five analog inputs and two analog outputs. For time-critical signals, the Siemens data sheet lists six high-speed counters and four high-speed outputs for PTO, PWM, or frequency output. The first communication interface is PROFINET IRT with an integrated 2-port switch. The specified bit execution time is 60 ns. Power is supplied at 24 V DC. A SIMATIC Memory Card is required for program and data storage. The integrated display has a diagonal of 3.45 cm, eight keys, and two mode buttons. Siemens documents a permissible supply range of 19.2 to 28.8 V DC for the CPU section; the permissible range for supplying the integrated digital inputs and outputs starts at 20.4 V DC. The module supports isochronous operation and I&M data from I&M0 to I&M3. The Siemens equipment manual gives enclosure dimensions of 85 × 147 × 129 mm and an approximate unit weight of 1,050 g. The order number binds these data to the documented CPU 1511C-1 PN version. Every visible technical value comes from the referenced Siemens documents. No undocumented firmware, installation, or replacement assumption is transferred to the product.
