Siemens 6ES7214-1AF40-0XB0 S7-1200F CPU 1214FC DC/DC/DC 14DI/10DO PLC

The Siemens 6ES7214-1AF40-0XB0 is a SIMATIC S7-1200F CPU 1214FC, a fail-safe compact PLC with DC/DC/DC I/O: 14 digital inputs, 10 digital outputs, and 2 analog inputs (0-10 V) onboard. It runs from 20.4-28.8 V DC, holds 200 KB of integrated program/data memory, and has one isolated PROFINET interface supporting PROFINET IO Controller/Device, OPC UA, and PROFIsafe.

Selection Notes

The "F" in CPU 1214FC adds PROFIsafe support to the standard 1214C feature set, so choose this variant when the same controller has to run standard machine logic and a safety function (e.g. an E-stop chain or safety door interlock) without a separate safety PLC. The 14DI/10DO/2AI onboard count and 200 KB program memory put it above the smaller S7-1200 CPUs in this family, giving headroom for programs that also need HSC or PTO channels. Up to 8 signal modules and 3 communication modules can be added, so the onboard I/O is a starting point, not a hard ceiling, for expanding the station.

Applications

Fits compact machines that combine standard sequencing with a safety function on the same controller - packaging cells, conveyor sections, and small assembly stations needing PROFIsafe alongside PROFINET IO control.
