It reads types J, K, T for general process, R and S for high-temp, plus L, U, and C for specialty applications. It does not accept RTD inputs (Pt100, Pt1000, Ni100, Ni1000) or voltage/current signals — this is strictly a millivolt-level thermocouple interface, so the cold-junction compensation is internal and the module expects bare TC wire, not a 4-20 mA transmitter. ## Temperature range and approvals for harsh environments The 40 mm width fits a standard S7-300 slot; the 125 mm height and 120 mm depth match the rest of the S7-300 family, so it aligns with neighbouring modules on the DIN rail without protruding.","metaTitle":"Siemens 6AG1331-7PF11-4AB0 Analog Input Module, 11 TC Types","metaDescription":"Siemens 6AG1331-7PF11-4AB0 analog input module supports 11 thermocouple types (B, C, E, J, K, L, N, R, S, T, U). -40 to 70 °C range, 40x125x120 mm.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Analog Input Modules"],"specifications":{"Max.":"70 °C","Min.":"-40 °C","Cu 10":"No","Depth":"120 mm","Width":"40 mm","title":"6AG1331-7PF11-4AB0","Height":"125 mm","Ni 100":"No","Ni 120":"No","Ni 200":"No","Ni 500":"No","Pt 100":"No","Pt 200":"No","Pt 500":"No","Type B":"Yes","Type C":"Yes","Type E":"Yes","Type J":"Yes","Type K":"Yes","Type L":"Yes","Type N":"Yes","Type R":"Yes","Type S":"Yes","Type T":"Yes","Type U":"Yes","CE mark":"Yes","Current":"No","Ni 1000":"No","Pt 1000":"No","Voltage":"No","EN 50155":"No","0 to +10 V":"No","0 to 20 mA":"No","1 V to 5 V":"No","EN 50121-4":"No","LG-Ni 1000":"No","Resistance":"No","1 V to 10 V":"No","KC approval":"Yes","UL approval":"Yes; File E239877","description":"SIPLUS S7-300 SM 331 8AI 40-pole based on 6ES7331-7PF11-0AB0 with conformal coating, 0…+60 °C, analog input isolated, 8 AI thermocouples type B, E, J, K, L, N, R, S, T TXK/TXK (L) according to GOST 16-bit, 50 ms, 1x 40-pole","-1 V to +1 V":"No","-5 V to +5 V":"No","Thermocouple":"Yes","0 To 150 Ohms":"No","0 To 300 Ohms":"No","0 To 600 Ohms":"No","4 mA to 20 mA":"No","-10 V to +10 V":"No","0 To 6000 Ohms":"No","Shielded, Max.":"100 m","Parameterizable":"Yes","Weight, approx.":"272 g","lifecycle_stage":"current","-10 mA to +10 mA":"No","-2.5 V to +2.5 V":"No","-20 mA to +20 mA":"No","-50 mV to +50 mV":"No","-80 mV to +80 mV":"No","Diagnostic alarm":"Yes; Parameterizable per group","Power loss, typ.":"3 W","Rated value (DC)":"24 V","For Thermocouples":"Type B, E, J, K, L, N, R, S.
