The diagnostic alarm and wire-break detection feed back to the CPU early, so you see a sensor fault before the loop goes dead. Operates from -40 °C to 70 °C ambient with atmospheric pressure from 795 to 1 080 hPa. Approved under cULus, UL, CSA, FM, KC, CE, and Marine, covering the common global panel certifications in one module. Mounts on the standard S7-1200 DIN rail; 70 mm width leaves room for a CPU and two more signal modules in a typical rack.","metaTitle":"Siemens 6ES7231-5PF32-0XB0 RTD Module, 70°C, -40°C","metaDescription":"Active Siemens S7-1200 analog input module for RTD/resistance.
