Siemens 6ES7212-1AG50-0XB0 SIMATIC S7-1200 CPU 1212C DC/DC/DC 8DI/6DO PLC

The Siemens 6ES7212-1AG50-0XB0 is a SIMATIC S7-1200 CPU 1212C DC/DC/DC compact controller with 8 onboard 24 V DC digital inputs, 6 digital outputs, and integrated PROFINET with a 2-port switch. It offers 150 KB program memory, 500 KB data memory, and up to 6 HSC channels at 100 kHz, running on 20.4-28.8 V DC supply.

Selection Notes

The 1212C's 8 DI / 6 DO onboard count and single expansion-board slot sit below the 1214C and 1215C in the family -- choose it for small machines that need PROFINET and up to 6 high-speed counters but won't grow past 3 communication modules and 6 signal modules. Four of the six outputs run as 100 kHz pulse outputs (Qa.0-Qa.3), useful for stepper or simple servo pulse-train control without a dedicated motion card, while the remaining two are standard 20 kHz outputs. With PROFINET IO Controller and Device roles both built in, the same CPU can act as an I/O master to remote stations or as a smart slave to a higher-level controller.

Applications

Small standalone machines, PROFINET I/O expansion, or embedded controllers needing onboard high-speed pulse outputs for basic positioning without a separate motion controller.
