Description

The CPU 1215C DC/DC/RLY is engineered to offer DC power efficiency combined with relay-based output flexibility. It runs on 24 V DC and includes 14 digital inputs, 10 relay outputs, 2 analog inputs (0–10 V), and 2 analog outputs (0–20 mA), making it capable of handling both digital control logic and analog process regulation. Relay outputs enable this CPU to handle a wide range of load types—DC and AC—ideal for applications where mixed electrical components are in use, such as building services or mixed-load industrial machines. This model also includes 125 KB of internal memory, two Ethernet PROFINET ports for network integration, and supports modular expansion via signal and communication modules. It is compatible with advanced features such as PID control, motion control, and high-speed counting, while the analog outputs are perfect for interfacing with actuators, VFDs, or analog gauges. It is designed for DIN rail mounting and is fully programmable via Siemens TIA Portal, offering ease of setup, simulation, and maintenance.
