Description

The Siemens CPU 1214C DC/DC/DC is a compact yet highly capable PLC suited for a wide variety of mid-level automation tasks. It features 14 digital inputs (24 V DC), 10 digital transistor outputs (24 V DC), and 2 analog inputs (0–10 V DC), all built into a compact DIN-rail mountable unit. With 100 KB of internal program memory, it enables the execution of moderately complex control logic for machinery, process handling, and automation lines. The transistor outputs offer fast switching times ideal for high-speed pulse output and time-critical digital tasks. This variant is powered by a 24 V DC supply and integrates seamlessly with Siemens’ TIA Portal software, supporting ladder logic (LAD), function blocks (FBD), and structured text (SCL). Its built-in PROFINET interface enables easy communication with HMI panels, SCADA systems, or other networked devices. The unit can be expanded with signal boards, signal modules, and communication modules, offering support for up to 8 signal modules. The CPU 1214C DC/DC/DC is commonly applied in packaging equipment, material handling, automated testing stations, and batch processing environments, especially where rapid digital control is critical.
