It accepts Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni200, Ni500, Ni1000, Cu10, Cu50, Cu100, and LG-Ni1000 RTD types — covering the common platinum, nickel, and copper curves used in process and HVAC loops. Each input uses an integrating measurement principle and supports wire-break detection, diagnostic alarms, and per-channel status readout. The module draws 1.5 W typical from the 24 V DC backplane supply. ## Active production, sourced per RFQ The closest functional peer is the standard S7-1200 SM 1231 RTD module (6ES7231-5PF32-0XB0), which shares the same 8-input RTD architecture but lacks the extended -40 °C to 70 °C temperature range and SIPLUS coating for harsh environments.","metaTitle":"Siemens 6AG1231-5PF32-4XB0 Analog Input Module, 8 RTD","metaDescription":"Siemens 6AG1231-5PF32-4XB0 analog input module with 8 RTD inputs.
