One parameterizable module covers thermocouples, resistance thermometers and standard process signals, which is what makes it a sensible single-line BOM entry for a mixed sensor panel rather than a dedicated card per signal type. The module carries a CE mark, a KC approval and a UL listing under file E239877, so it is documented for North American, European and Korean panel builds. ## What it will and will not read The supported thermocouple list is B, E, J, K, N; R, S, T, L and U are not on the supported list, so a Type K or Type J probe is the safe default and a Type T low-temperature bath probe needs a different module. RTD coverage is Pt 100 and Ni 100; Cu 10 is not supported. The module is not specified against the rail vehicle or trackside EMC standards, so those environments need a different variant; the listed industrial compliance is UL/CE/KC only.","metaTitle":"Siemens 6AG1331-7KB02-2AB0 AI module, -40 to 70 °C","metaDescription":"Siemens 6AG1331-7KB02-2AB0 analog input module for SIPLUS, thermocouple + RTD + voltage/current, -40 °C to 70 °C, UL/CE/KC.
