RTD support covers Pt100 (standard/climate), Ni100 (standard/climate), Ni1000, and LG-Ni1000; thermocouple and Cu10 are not supported. Voltage ranges include ±10 V, 1 to 5 V, ±1 V, and ±5 V; current inputs accept 0 to 20 mA and 4 to 20 mA; resistance measurement up to 600 Ω is also available. The module occupies one 40 mm slot in the S7-300 rack (125 mm height, 117 mm depth), fitting standard DIN-rail mounting.","metaTitle":"6ES7331-1KF01-0AB0 SIMATIC S7-300 Analog Input Module, 8 AI,","metaDescription":"Siemens 6ES7331-1KF01-0AB0 analog input module for S7-300: 8 channels, supports Pt100, Ni100, Ni1000 RTDs, voltage (±10V, 1-5V) and current (0/4-20mA) signals. 40 mm wide, 117 mm d","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Analog Input Modules"],"specifications":{"Cu 10":"No","Depth":"117 mm","Width":"40 mm","Height":"125 mm","Ni 100":"Yes; Standard/climate","Ni 120":"No","Ni 200":"No","Ni 500":"No","Pt 100":"Yes; Standard/climate","Pt 200":"No","Pt 500":"No","Type B":"No","Type C":"No","Type E":"No","Type J":"No","Type K":"No","Type L":"No","Type N":"No","Type R":"No","Type S":"No","Type T":"No","Type U":"No","Current":"Yes","Ni 1000":"Yes","Pt 1000":"No","Voltage":"Yes","0 to +10 V":"Yes","0 to 20 mA":"Yes","1 V to 5 V":"Yes","LG-Ni 1000":"Yes; Standard/climate","Resistance":"Yes","1 V to 10 V":"No","-1 V to +1 V":"Yes","-5 V to +5 V":"Yes","Thermocouple":"No","0 To 150 Ohms":"No","0 To 300 Ohms":"No","0 To 600 Ohms":"Yes","4 mA to 20 mA":"Yes","-10 V to +10 V":"Yes","0 To 6000 Ohms":"Yes","Shielded, Max.":"200 m; max. 50 m at 50 mV","Parameterizable":"Yes","Weight, approx.":"250 g","lifecycle_stage":"eol_hot","-10 mA to +10 mA":"No","-2.5 V to +2.5 V":"No","-20 mA to +20 mA":"Yes","-50 mV to +50 mV":"Yes","-80 mV to +80 mV":"No","Diagnostic alarm":"No","Power loss, typ.":"0.4 W","Limit value alarm":"No","-250 mV to +250 mV":"No","-3.2 mA to +3.2 mA":"No","-500 mV to +500 mV":"Yes","Between The Channels":"No","Diagnostics function":"No","Group error SF (red)":"No","Isolation tested with":"500 V DC","Resistance thermometer":"Yes","For Voltage Measurement":"Yes","Number of analog inputs":"8","Type TXK/TXK(L) to GOST":"No","Required Front Connector":"40-pin","Input resistance (Ni 100)":"100 MΩ","Input resistance (Pt 100)":"100 MΩ","Basic conversion time (ms)":"66 / 55 ms","For Resistance Thermometer":"yes; Pt100 standard/air con.; Ni100 standard/air con.; Ni1000 standard/air con.; LG-Ni1000 standard/air con.","For resistance measurement":"8","Input resistance (Ni 1000)":"100 MΩ","Input resistance (0 to 10 V)":"100 kΩ","Input resistance (0 to 20 mA)":"50 Ω","Input resistance (1 V to 5 V)":"100 kΩ","Input resistance (LG-Ni 1000)":"100 MΩ","Diagnostic information readable":"No","Input resistance (-1 V to +1 V)":"100 kΩ","Input resistance (-5 V to +5 V)":"100 kΩ","from backplane bus 5 V DC, max.":"90 mA","Input resistance (0 to 600 ohms)":"100 MΩ","Input resistance (4 mA to 20 mA)":"50 Ω","Input resistance (-10 V to +10 V)":"100 kΩ","Input resistance (0 to 6000 ohms)":"100 MΩ","Integration time, parameterizable":"Yes; 60 / 50 ms","Input resistance (-20 mA to +20 mA)":"50 Ω","Input resistance (-50 mV to +50 mV)":"100 kΩ","Input resistance (-500 mV to +500 mV)":"100 kΩ","Between The Channels And Backplane Bus":"Yes","Current, relative to input range, (+/-)":"0.3 %; ±20 mA, 0 to 20 mA, 4 to 20 mA","Voltage, relative to input range, (+/-)":"0.4 %; 0.4% (±5 V, 10 V, 1 to 5 V, 0 to 10 V); 0.3% (±50 mV, 500 mV, 1 V)","Resistance, relative to input range, (+/-)":"0.3 %; 0 to 6 kohms, 0 to 600 kohms","For Current Measurement As 2-Wire Transducer":"Yes; with external supply","For Current Measurement As 4-Wire Transducer":"Yes","For Resistance Measurement With Two-Wire Connection":"Yes","For Resistance Measurement With Four-Wire Connection":"Yes","Resolution with overrange (bit including sign), max.":"13 bit","For Resistance Measurement With Three-Wire Connection":"Yes","Resistance thermometer, relative to input range, (+/-)":"1 Kelvin (Pt100, Ni100, standard); 0.8 Kelvin (Pt100, Ni100, climatic; Ni1000, LG-Ni1000, standard; Ni1000, LG-Ni1000, climatic)","Interference voltage suppression for interference frequency f1 in Hz":"50 / 60 Hz","Permissible Input Current For Current Input (Destruction Limit), Max.":"40 mA","Permissible Input Voltage For Voltage Input (Destruction Limit), Max.":"30 V; 12 V continuous, 30 V for max. 1 s"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$122.22","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=272356&mlfb=6ES7331-1KF01-0AB0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7331-1KF01-0AB0/alternatives.json"},"ai":{"faq":[{"question":"What RTD types does the 6ES7331-1KF01-0AB0 support?","answer":"It supports Pt100 (standard/climate), Ni100 (standard/climate), Ni1000, and LG-Ni1000.
