Description

About the CPU 1214FC DC/DC/DC

The Siemens 6ES7214-1AF50-0XB0 is a SIMATIC S7-1200 CPU 1214FC DC/DC/DC fail-safe compact CPU with 14 integrated 24 V DC digital inputs and 10 digital outputs. It runs on 20.4-28.8 V DC, holds 300 KB of program memory and 750 KB of data memory with 20 KB retentive, and communicates over a 2-port PROFINET interface with integrated switch.

Selection Notes

The FC suffix marks a fail-safe compact CPU: alongside standard logic it accepts F-blocks for PROFIsafe-rated safety functions in TIA Portal without a separate safety controller. With 14 integrated digital inputs, 8 usable for high-speed counting up to 100 kHz, and 10 outputs, 4 rated to 100 kHz, it covers small-to-medium I/O counts without add-on signal modules. Pick it over a non-fail-safe CPU when the machine needs integrated safety, and reserve a larger-memory CPU in the range for programs exceeding the 300 KB/750 KB program/data split.

Applications

Suited to machine safety applications needing integrated F-CPU logic on a single controller: guard interlocking, E-stop chains, and light-curtain monitoring over PROFINET, alongside standard motion counting via the onboard 100 kHz high-speed counters for encoder-based positioning and quadrature-phase measurement tasks.
