Power and environmental fit
The 6AG1212-1AE31-4XB0: Rated for 24 V DC with a permissible range of 20.4 V to 28.8 V, the CPU handles dips and standard industrial power rails. Ambient temperature rating from -40 °C to 70 °C means it can be placed in outdoor cabinets, cold storage, or hot enclosures without forced cooling. Dimensions are 90 mm wide, 100 mm high, and 75 mm deep – standard for a Siemens S7-1200 form factor. Work memory is 1 Mbyte integrated, and a typical backup time of 480 hours retains program and data across power loss.
