Product details

What this CPU brings to the panel

The Siemens 6AG1214-1AG31-5XB0 is a SIPLUS variant of the S7-1200 CPU 1214C, built for extended ambient temperature operation from -40 °C to 70 °C. It carries 4 MB of integrated work memory for program and data, and supports LAD, FBD, and SCL programming languages — covering structured text, function block, and ladder logic. The onboard PROFINET interface handles TCP/IP, MODBUS, and UDP communication.

Supply and footprint

Accepts 24 VDC within a permissible range of 20.4 V to 28.8 V. Dimensions are 110 mm wide, 100 mm high, 75 mm deep — standard S7-1200 rail mounting.

Frequently asked questions
