Description

The Siemens CPU 1212C DC/DC/DC is a robust and compact programmable logic controller designed for medium-scale control applications that require both flexibility and performance in a space-saving format. It operates using a 24 V DC power supply and includes 8 digital inputs, 6 digital transistor outputs (sourcing type), and 2 analog voltage inputs (0–10 V), allowing it to handle a wide range of sensor and actuator configurations. With a user program memory of 75 KB and data memory of 50 KB, the 1212C model is capable of executing complex logic functions, motion control through integrated high-speed counters, and advanced data handling tasks. These capabilities make it ideal for control systems that demand responsiveness, such as conveyor automation, small process equipment, machine tools, and embedded industrial solutions. The integrated PROFINET interface enables fast and reliable communication with SCADA systems, HMIs, and distributed I/O, supporting modern industrial networking requirements. In addition, the CPU can be expanded with up to three signal boards and eight communication or signal modules, offering substantial scalability without sacrificing its compact design. This makes it particularly well-suited for OEM applications, modular machines, and smart infrastructure systems where both control performance and space efficiency are critical.
