Supports all common RTD types (Pt100, Cu10, Ni100, Pt1000, and more) and thermocouple types B, C, E, J, K, N, R, S, T — with Standard/climate compensation curves. Also handles PTC and MSI (Measuring System Interface) inputs. Runs on the backplane bus; no separate supply needed. For three-wire RTD measurements, the module alternates conductor compensation with the actual measurement, which adds one full cycle per reading. Plan scan time accordingly if mixing two-wire and three-wire channels on the same block. Dimensions 147 mm high × 35 mm wide × 129 mm deep — fits any S7-1200 base unit left-side expansion slot or ET 200SP remote station. Green RUN and red ERROR LEDs on the front panel for immediate channel-level diagnostics. Identification and maintenance data (I&M0–I&M3) stored onboard, so the module can be swapped without reconfiguring the asset database if the replacement writes the same I&M records.","metaTitle":"Siemens 6AG1531-7PF00-4AB0 SIPLUS S7-1200 AI 8xRTD/TC","metaDescription":"SIPLUS S7-1200 analog input module, 8 channels RTD/TC, MSI yes, PTC yes, Pt100, 129 mm depth, I&M0-3.
