⚙️ Product Overview
SIMATIC S7-1200, CPU 1212C, compact CPU, DC/DC/DC, onboard I/O: 8 DI 24 V DC; 6 DO 24 V DC; 2 AI 0-10 V DC, power supply: DC 20.4-28.8 V DC, program/data memory 100 KB
The Siemens SIMATIC S7-1200 CPU 1212C DC/DC/DC is a compact, mid-range PLC built for fast, reliable control in small to medium automation systems. Powered by 24 V DC, it features DC digital inputs and high-speed transistor (DC) outputs, making it ideal for applications that require quick switching and precise control.
As a Compact (C) CPU, it integrates the CPU, digital I/O, and analog inputs in one unit—saving cabinet space and simplifying wiring. With built-in PROFINET (Industrial Ethernet) and full support in TIA Portal, it delivers easy engineering, fast commissioning, and strong diagnostics. Typical uses include packaging machines, conveyors, dosing systems, pumps, compressors, and OEM control panels.
