Description

The CPU 1215C AC/DC/RLY is a flexible and powerful PLC controller from the Siemens S7-1200 family, suitable for a wide variety of industrial applications. It operates on a wide AC input range (85–264 V AC), eliminating the need for external power converters. It features 14 digital inputs (24 V DC), 10 relay outputs (capable of switching both AC and DC loads), 2 analog voltage inputs (0–10 V), and 2 analog current outputs (0–20 mA), making it well-suited for systems requiring both discrete and analog control. Relay outputs provide the advantage of electrical isolation and multi-voltage switching, which makes this model ideal for controlling solenoid valves, contactors, or pilot lights in HVAC, building automation, or water treatment systems. The inclusion of dual PROFINET ports ensures high-speed communication and device networking, enabling scalable integration into distributed architectures. With its 125 KB program memory and built-in analog I/O, this CPU eliminates the need for multiple expansion modules, simplifying control panel design. Fully supported in TIA Portal, it allows efficient project configuration, code simulation, and remote diagnostics.
