Siemens 6ES7212-1AF50-0XB0 SIMATIC S7-1200 CPU 1212FC DC/DC/DC 8DI/6DO Programmable Logic Controller

The Siemens 6ES7212-1AF50-0XB0 is a SIMATIC S7-1200 G2 failsafe compact CPU 1212FC DC/DC/DC with 8 onboard digital inputs and 6 digital outputs at 24 V DC, 200 KB program memory, 500 KB data memory, and 20 KB retentive memory. It runs on 20.4-28.8 V DC supply, integrates a 2-port PROFINET switch with IRT and isochronous mode, and supports up to 6 high-speed counters at 100 kHz.

Selection Notes

The 'FC' designation (failsafe compact) distinguishes this CPU from the standard 1212C: it accepts F-blocks in the same user program for basic safety functions, without a separate F-CPU or dedicated safety PLC. With only 8 DI / 6 DO onboard and a 6-module expansion limit, it fits small machines or standalone stations rather than large I/O counts — projects needing more channels should move to the 1214 or 1215 CPUs in the same DC/DC/DC family. The integrated 2-port PROFINET switch with IRT and isochronous mode supports motion-synchronized I/O without an added communication processor.

Applications

Standalone or small-machine control with an onboard safety function requirement — packaging, conveyor, or material-handling cells needing PROFINET connectivity and integrated fail-safe I/O without a dedicated safety CPU.
