This unit is a common pick for ammonia/CO2 refrigeration skids and freezer room sequencing panels where the hardware sits inside the cold envelope. Programmable in LAD, FBD, and SCL. The integrated PROFINET interface with TCP/IP and autocrossing connects directly to remote I/O, VFDs, or SCADA, eliminating the need for a separate communication module. ## Data retention and backup in sub-zero service Cold storage power outages can be frequent during defrost cycles or utility dips. This CPU includes a removable EEPROM for entire project backup and a typical 240 hour memory backup time — important for keeping retentive data like setpoints, timer values, and alarm history through extended freezes. The integral EEPROM also makes maintenance-free project reload possible if you need to swap a unit in the field. The 24 V DC supply accepts a permissible range of 20.4 V to 28.8 V, giving headroom for voltage drop along long cable runs in large freezer warehouses. ## Regulatory and compliance picture The CPU carries cULus, CE, and FM approvals, which covers most North American and European refrigeration panel builds. FM approval is specifically relevant for ammonia machinery rooms where the authority having jurisdiction may require FM-listed equipment.","metaTitle":"Siemens 6ES7212-1AD30-0XB0 S7-1200 CPU, -40 to 70°C","metaDescription":"Siemens S7-1200 CPU 1212C, rated -40 to 70°C, supports LAD/FBD/SCL, PROFINET, 1 MB memory, cULus/CE/FM.
