Product details

The Siemens 6AG1211-1AD30-5XB0 is the SIPLUS variant of the standard S7-1200 CPU 1211C — purpose-built for environments where a standard 0–55°C part won't hold. The entire unit, from the -40°C cold start to the 70°C ambient ceiling, runs without derating. Varnish-coated board, wider electrolytic caps, stiffer oscillator. If a panel lives unheated in a Canadian plant or inside a refrigerated warehouse, this is the one that stays up. One in the cabinet, and you sleep.

How it sits against the standard sibling

The closest functional peer is 6ES7212-1AD30-0XB0 (standard S7-1200 1212C). Same 1 MB load memory, same I/O layout, same PROFINET interface. What changes: the standard CPU lives 0–55°C ambient and lacks conformal coating. The SIPLUS here covers -40 to 70°C and carries full coating against moisture and condensation. Panel wiring is identical — same 90 mm width, same 24 V pinout, same front connector. You can pull a standard unit and drop this in without touching the cabinet. The delta in part number should be the only procurement headache; everything else is transparent to the machine.

Compliance documentation

UL listed, cULus approved, and CE marked per the nameplate.

Frequently asked questions

Is 6AG1211-1AD30-5XB0 a direct mechanical replacement for a standard S7-1200 1212C (e.g., 6ES7212-1AD30-0XB0)?

Yes – same 90 mm width, 100 mm height, 75 mm depth, same front connector pinout and mounting on standard DIN rail. No rewiring needed.

What compliance marks does the SIPLUS carry?

UL and cULus approval, plus CE mark. Evidence confirms these approvals directly on the listing.

Does this CPU support both FBD and LAD programming?

Yes, both Function Block Diagram (FBD) and Ladder Logic (LAD) are explicitly supported, per the spec list.
