About Siemens, SIPLUS S7-1200, 6AG1231-5PF32-2XB0, 0 DO, 0 DI, 0 AO, 8 AI, Single-phase, 24 V DC.

The Siemens SIPLUS S7-1200 SM 1231 RTD analog input expansion module (model number 6AG1231-5PF32-2XB0) features 8 analog inputs (AI) specialized for resistance temperature detectors (RTD), with 0 digital outputs (DO), 0 digital inputs (DI), and 0 analog outputs (AO). Derived from the standard 6ES7231-5PF32-0XB0 baseline component, it processes high-precision thermal diagnostics using a 15-bit plus sign resolution across Pt100, Pt1000, and Ni1000 sensor tracks. Operating within a single-phase architecture powered by a standard 24 V DC voltage supply, this module is reinforced with a ruggedized environmental conformal coating. This safely protects internal logic boards from heavy condensation, frost, and active industrial contaminants across an extended temperature range of -40 to +70 C (with a cold startup tolerance down to -25 C).
