Measurement is integrating (no thermocouple support – the thermocouple field shows 'No'). Diagnostics can be read out over the backplane, and the alarms are parameterizable (the alarm field says 'Yes'). That saves panel space by eliminating external alarm relays. For a bin that already holds standard S7-1200 modules, this RTD input drops into the same mounting rail and uses the standard 24 V DC supply. No separate sensor supply needed – the module provides excitation for two-wire RTDs. Wire-break detection per channel ('Wire-break Yes') flags open loops without additional hardware.","metaTitle":"Siemens 6ES7231-5PD30-0XB0 SM 1231 RTD, 8-ch, -40..70°C","metaDescription":"Siemens SIMATIC S7-1200 SM 1231 RTD input module, 8 channels, -40 to 70 °C, diagnostic alarm, wire-break detection, RTD types Pt100..Ni1000.
