Official product identity

Siemens SIMATIC S7-1200 CPU 1214C compact CPU, order number 6ES7214-1AG31-0XB0, DC/DC/DC version.

Integrated control resources

Onboard I/O comprises 14 digital inputs at 24 V DC, 10 digital outputs at 24 V DC and 2 analog inputs for 0-10 V DC signals.

Power and memory

Rated supply range is 20.4-28.8 V DC. The official product description specifies 75 KB program/data memory.

Lifecycle and selection

Siemens lists this order number as phased out/discontinued. The stated successor is 6ES7214-1AG40-0XB0 and is conditionally compatible, so project and hardware checks are required before replacement.

Physical procurement data

Official packaging dimensions are 115 x 111 x 84 mm (L x W x H). Net weight is 0.416 kg.

Integrated I/O

Digital inputs

Fourteen onboard digital inputs are specified for 24 V DC signals, allowing direct connection of machine and process input devices within the documented electrical range.

Digital outputs

Ten onboard digital outputs use 24 V DC. The DC/DC/DC designation identifies DC supply, DC inputs and DC transistor outputs for this CPU variant.

Analog inputs

Two integrated analog inputs accept 0-10 V DC signals. Engineering must confirm the sensor signal type and the required scaling before commissioning.

Power & Memory

Supply range

The official product description specifies a 20.4-28.8 V DC supply range. Power design should stay within this range under normal load and transient conditions.

Program and data memory

The stated program/data memory capacity is 75 KB. The engineering project should be checked against the available memory before migration or expansion.

Compact architecture

The CPU combines controller processing, power interface and onboard mixed I/O in one compact SIMATIC S7-1200 device.

Lifecycle

Product status

Siemens marks 6ES7214-1AG31-0XB0 as phased out/discontinued. Procurement should therefore verify exact condition, serial data and traceable stock evidence.

Successor information

Siemens identifies 6ES7214-1AG40-0XB0 as the successor and describes compatibility as conditional.

Replacement planning

A replacement decision must account for the saved TIA Portal project, firmware level, wiring, expansion modules and machine validation requirements.

Compatibility

Exact order number

The complete order number 6ES7214-1AG31-0XB0 identifies the CPU 1214C DC/DC/DC version with 14 DI, 10 DO and 2 AI. Suffixes must not be shortened in procurement documents.

Electrical match

Confirm 20.4-28.8 V DC supply, 24 V DC digital I/O and 0-10 V DC analog input compatibility with the installed system.

Project and hardware check

Before using the stated successor or a similar CPU, compare project compatibility, firmware, memory, onboard I/O allocation, expansion hardware and commissioning requirements.

FAQ

Q1. How can a buyer verify that the quotation is for the exact complete model?

Require the quotation, label photographs and packing information to show 6ES7214-1AG31-0XB0 in full. Cross-check CPU 1214C, DC/DC/DC, 14 DI, 10 DO, 2 AI, 20.4-28.8 V DC and 75 KB memory against the Siemens product data.

Q2. How can New, Used and Refurbished condition be distinguished?

Request current high-resolution photos of the Siemens label, order number, serial/date codes, housing, terminals, seals and packaging. Ask for a written condition declaration and evidence that matches the photographed unit.

Q3. How should supplier legitimacy and reliability be checked?

Verify the legal company name, invoice details, traceable contact information, written return terms and the ability to provide consistent serial-numbered evidence for the exact 6ES7214-1AG31-0XB0 offered.

Q4. Which engineering points must be confirmed before purchase?

Confirm the DC/DC/DC version, 20.4-28.8 V DC supply, 14 digital inputs, 10 digital outputs, two 0-10 V analog inputs, 75 KB memory, firmware level and compatibility with the saved TIA Portal project and installed expansion hardware.

Q5. What physical evidence should be requested before payment?

Ask for timestamped photos or video showing the complete order number, Siemens label, serial/date codes, terminal condition, housing, power-up or diagnostic state where applicable, and the exact packing contents.

Q6. Can a similar suffix or the stated successor be used as a direct replacement?

Do not assume direct interchangeability. Siemens lists 6ES7214-1AG40-0XB0 as a conditionally compatible successor; verify project conversion, firmware, wiring, onboard I/O mapping, expansion modules and machine validation before substitution.
