6ES7214-1AG40-0XB0

Product information

The 6ES7214-1AG40-0XB0 is a Siemens SIMATIC S7-1200 compact CPU designated CPU 1214C in the DC/DC/DC configuration — 24 V DC supply, 24 V DC inputs and solid-state 24 V DC outputs. It integrates 14 digital inputs, 10 digital outputs and 2 analog inputs into one controller, with 150 KB of work memory, 4 MB of load memory and two PROFINET ports on an integrated switch.

The DC/DC/DC output stage is the reason to choose this variant rather than the relay version: transistor outputs switch far faster and do not wear out mechanically, which matters where the outputs pulse frequently. Where AC loads or mixed load voltages must be switched directly, the AC/DC/relay variant 6ES7214-1BG40-0XB0 is the equivalent CPU instead.

Specifications as published in Siemens product data for this article number. Verify against the nameplate of the unit offered to you — hardware functional status and firmware can differ between production runs.

Lifecycle status

Siemens currently lists this article number as an active product, with phase-out announced effective 2026-11-01, and identifies the SIMATIC S7-1200 G2 generation as the successor platform. For buyers specifying this CPU into new builds, that date is worth planning around; for buyers maintaining existing S7-1200 installations, the CPU itself remains the component the existing project was engineered for.

Typical applications

• Machine control where digital outputs drive fast-switching 24 V DC loads such as valves, contactors via interface relays, or indicator circuits
• Pulse-train and motion-related tasks that use the integrated transistor outputs
• Packaging, conveying and assembly equipment built on a compact controller rather than a modular rack
• Replacement on existing S7-1200 installations where the same ordering code is already in use

Application examples describe typical uses of this product type. Suitability for your own installation must be confirmed against your engineering documentation.

Frequently asked questions

Is the 6ES7214-1AG40-0XB0 still produced?
Siemens lists it as an active product but has announced phase-out effective 2026-11-01, with the S7-1200 G2 generation named as successor. Confirm current availability for the revision you need.

Can the work memory be expanded?
No. The 150 kbyte work memory is integrated and not expandable. If your program needs more, the CPU 1215C or a G2 platform CPU is the usual route.

Does this CPU require a SIMATIC memory card?
No. Unlike the S7-1500 CPUs, the S7-1200 stores the program in its integrated load memory. A memory card is optional and used for program transfer, recipe data or firmware update.

What is the difference between DC/DC/DC and AC/DC/Relay?
The suffix describes supply and output stage. DC/DC/DC runs from 24 V DC and switches solid-state DC outputs; AC/DC/Relay runs from 85–264 V AC and switches relay contacts rated 2 A.

Which engineering software version do I need?
Siemens lists STEP 7 V20 or higher for firmware V4.7 of this article number.

What is the price and lead time?
Both are confirmed individually against current availability for the specific revision and quantity. Submit your requirement and we will respond with a firm offer.
