SIPLUS S7-1200 CPU 1214C DC/DC/DC — 6AG12141AG402XB0
Family positioning and part number decode
The 6AG12141AG402XB0 belongs to the Siemens SIPLUS S7-1200 compact controller series. The MPN prefix 6AG1 denotes the SIPLUS extended-temperature variant; the subsequent digits 214 identify the CPU 1214 class, and the character pair AG encodes the 24 V DC input / 24 V DC transistor output (DC/DC/D) configuration. The suffix 402XB0 reflects the onboard I/O count and package form factor. Siemens orders these parts under the SIPLUS extended-temperature family designation to distinguish them from the standard S7-1200 range.

Selection trade-offs within the SIPLUS CPU 1214 family
- The DC/DC/D output type (transistor) suits sinking-load applications; relay-output variants (suffix
HG,BG) handle AC or higher-current loads but have different switching寿命 characteristics. - The 100 kB memory in 6AG12141AG402XB0 is mid-range; higher-memory options such as 6AG12141AF405XB0 (125 kB) or 6AG12141HF405XB0 (125 kB) may reduce program-density pressure but increase unit cost.
- Temperature range 40°C–70°C positions this variant for cabinet-mounted applications with elevated ambient conditions; the 25°C–55°C variants (6AG12141AF405XB0, 6AG12141HF405XB0) serve climate-controlled environments.
- Non-expandable constraint means no Signal Board or communication module additions; a CPU 1214F fail-safe variant (6AG12141AF405XB0, 6AG12141HF405XB0) provides functional safety functions only when the application demands it.

Why the peers are listed: 6AG12141AF405XB0 shares the same DC/DC/D output configuration, panel-mount box encapsulation, and non-expandable architecture, differing in expanded memory (125 kB) and a narrower temperature ceiling. 6AG12141HG402XB0 and 6AG12141BG405XB0 share 100 kB memory and identical input counts but use relay outputs, making them candidates for AC load switching without external contactors.

FAQ
Does 6AG12141AG402XB0 support PROFINET or Ethernet communication? The SIPLUS S7-1200 CPU 1214 family typically integrates a single PROFINET port; however, communication interface details are not present in the on-record specifications and should be confirmed against the ordering documentation for this exact MPN suffix.
Can 6AG12141AG402XB0 use the same expansion modules as the standard S7-1200 CPU 1214C? The primary part is non-expandable per the on-record specification, so onboard expansion is not supported regardless of module compatibility.
What load type is recommended for the 10 pulse outputs on 6AG12141AG402XB0? The DC/DC/D configuration provides transistor outputs suitable for 24 V DC sinking loads. For inductive or high-inrush loads, a relay-output variant should be evaluated separately.
