Product details

The Siemens 6AG1211-1BE31-2XB0 is a SIPLUS S7-1200 CPU designed for extended temperature operation from -40 °C to 70 °C, with a 24 V DC supply permissible range of 20.4 V to 28.8 V, and supports FBD, LAD, and SCL programming languages.

The -40 °C to 70 °C operating range puts this CPU outside the standard 0–60 °C envelope — it belongs in outdoor cabinets, cold storage, or hot process areas where the standard S7-1200 would derate. Supply voltage tolerance is 20.4 V to 28.8 V DC, so a nominal 24 V rail with 10 % sag stays within spec; brownout ride-through depends on the load side, not the CPU. I/O addressing capacity is 1 024 bytes each for inputs and outputs — enough for a medium local rack; if your application exceeds that, you need a higher-end CPU. Backup time is 480 h typical, so a multi-day power failure won’t lose retentive data — useful for remote or intermittent mains sites.
