Siemens 6ES7214-1HF40-0XB0 SIMATIC S7-1200 CPU 1214FC DC/DC/Relay 14DI 10DO 2AI Programmable Logic Controller

The Siemens 6ES7214-1HF40-0XB0 is a SIMATIC S7-1200 CPU 1214FC with DC/DC/relay circuitry, integrating 14 DI 24V DC, 10 relay DO rated 2 A, and 2 AI 0-10V DC on one compact body. It runs from 20.4-28.8V DC, holds 200 KB of work memory, and communicates over a single isolated PROFINET port with PROFINET IO Controller and Device roles. Firmware V4.7 supports STEP 7 V20 or higher.

Selection Notes

The FC suffix marks this as the fail-safe-capable compact CPU in the S7-1200 line, so choose it over a standard 1214C when the application needs F-blocks and PROFIsafe on the same PROFINET port rather than a separate safety controller. Ten relay outputs rated 2 A each suit switching contactors or solenoid loads directly, where a transistor-output 1214C would need external relays for the same current. The single PROFINET port with prioritized startup for up to 16 IO devices sets the ceiling on how large a distributed I/O segment this CPU can drive without an added CM.

Applications

Used as the controller in compact machines and skids needing on-board relay outputs, such as material handling stations, packaging cells, and small process skids, where PROFINET IO Controller and Device roles let it both host distributed I/O and act as an IO Device to a higher-level PLC.
