It runs on 24 V DC (20.4 to 28.8 V permissible range) and lives through ambient temperatures from -40 °C to 70 °C. That's the kind of thermal headroom you need when the controller sits above a hot pump or inside a metal enclosure with no air conditioning. Program it in LAD, FBD, or SCL — whatever your existing codebase or team preference dictates. The CPU also handles MODBUS RTU and TCP/IP, PROFIBUS, and AS-Interface out of the gate, with an integrated Ethernet port that supports UDP and autocrossing. ## Sourcing & Compliance Carries cULus, CE, FM, UL, and CSA approvals, so it slides into panels destined for North America, Europe, or export markets without extra certification hurdles.","metaTitle":"Siemens 6ES7211-1BE31-0XB0 S7-1200 CPU, -40 to 70°C","metaDescription":"Siemens 6ES7211-1BE31-0XB0 S7-1200 CPU 1211C compact PLC. 24 V DC supply, wide -40 to 70°C range.
