It accepts voltage signals from -10 V to +10 V and current signals from 0 to 20 mA or 4 to 20 mA, making it suitable for direct connection to standard process transmitters without external signal conditioners. The module draws power from a 24 V DC backplane supply and dissipates up to 7.8 W, which should be factored into the rack's total power budget. ## Mechanical fit and wiring constraints Unshielded sensor cables can run up to 600 m, but thermocouple and 80 mV signal runs are limited to 50 m with shielded cable to maintain signal integrity. Digital inputs interpret 13 to 30 V as signal \"1\" and -3 to +5 V as signal \"0\", with a typical input current of 7 mA at signal \"1\".","metaTitle":"Siemens 6ES7355-2CH00-0AE0 FM 355-2 C, 4 Analog Inputs, EOL","metaDescription":"Siemens 6ES7355-2CH00-0AE0 FM 355-2 C controller module for SIMATIC S7-300. 4 analog inputs for thermocouples (B, E, J, K, R, S) and Pt 100 RTDs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC I/O & Expansion Modules"],"specifications":{"Depth":"120 mm","Width":"80 mm","title":"6ES7355-2CH00-0AE0","Height":"125 mm","Pt 100":"Yes","Type B":"Yes","Type E":"Yes","Type J":"Yes","Type K":"Yes","Type R":"Yes","Type S":"Yes","Counter":"No","Current":"Yes","Voltage":"Yes","0 to 10 V":"Yes","0 to +10 V":"Yes","0 to 20 mA":"Yes","description":"SIMATIC S7-300, temperature Control Unit FM 355-2 C, 4 channels, continuous, 4 AI+8 DI+4 AO incl. multi-language configuration package, Manual and Getting Started (de, de, fr, en it) on CD-ROM","0 to 23.5 mA":"Yes","Thermocouple":"Yes","2-Wire Sensor":"Yes","4 mA to 20 mA":"Yes","-10 V to +10 V":"Yes","For Signal \"0\"":"-3 to +5V","For Signal \"1\"":"13 to 30V","Shielded, Max.":"200 m; 50 m at 80 mV and thermocouples","Parameterizable":"Yes","Weight, approx.":"470 g","lifecycle_stage":"eol_hot","Power loss, max.":"7.8 W","Power loss, typ.":"6.5 W","Rated value (DC)":"24 V","Unshielded, Max.":"600 m","For Thermocouples":"Type B, E, J, K, R, S","For Inductive Load":"0.5 ms","For Resistive Load":"0.1 ms","-1.75 V to +11.75 V":"Yes","-3.5 mA to +23.5 mA":"Yes","For Capacitive Load":"3.3 ms","Between The Channels":"No","For Signal \"1\", Typ.":"7 mA","Isolation tested with":"500 V DC","Resistance thermometer":"Yes","For Voltage Measurement":"Yes","Number of analog inputs":"4","Number of analog outputs":"4","Number of digital inputs":"8","Required Front Connector":"2x 20-pin","Input resistance (Pt 100)":"10 MΩ","Input resistance (Type B)":"10 MΩ","Input resistance (Type E)":"10 MΩ","Input resistance (Type K)":"10 MΩ","Input resistance (Type R)":"10 MΩ","Input resistance (Type S)":"10 MΩ","Input resistance (type J)":"10 MΩ","For Resistance Thermometer":"Pt100 (standard)","With Current Outputs, Max.":"500 Ω","With Voltage Outputs, Min.":"1 kΩ","Input resistance (0 to 10 V)":"100 kΩ","Input resistance (0 to 20 mA)":"50 Ω","Substitute values connectable":"Yes; Parameterizable","Input resistance (0 to 23.5 mA)":"50 Ω","from backplane bus 5 V DC, max.":"75 mA; typ. 50 mA","Input resistance (4 mA to 20 mA)":"50 Ω","Internal Temperature Compensation":"Yes","Number of closed-loop controllers":"4","permissible range, lower limit (DC)":"20.4 V","permissible range, upper limit (DC)":"28.8 V","Current output, no-load voltage, max.":"18 V","Between The Channels And Backplane Bus":"Yes; Optocoupler","For Current Output Two-Wire Connection":"Yes","For Voltage Output Two-Wire Connection":"Yes","Input resistance (-1.75 V to +11.75 V)":"100 kΩ","Input resistance (-3.5 mA to +23.5 mA)":"50 Ω","Current, relative to input range, (+/-)":"0.04 %; ±0.04 to ±0.5 %","Voltage, relative to input range, (+/-)":"0.04 %; ±0.04 to ±0.5 %","Current, relative to output range, (+/-)":"0.5 %","Voltage output, short-circuit protection":"Yes","Voltage, relative to output range, (+/-)":"0.4 %","from load voltage L+ (without load), max.":"310 mA; Typ. 260 mA","With Current Outputs, Inductive Load, Max.":"1 mH","Voltage output, short-circuit current, max.":"25 mA","With Voltage Outputs, Capacitive Load, Max.":"1 µF","For Current Measurement As 4-Wire Transducer":"Yes","external temperature compensation with Pt100":"Yes","Permissible Quiescent Current (2-Wire Sensor), Max.":"1.5 mA","Resolution with overrange (bit including sign), max.":"14 bit","Resistance thermometer, relative to input range, (+/-)":"0.04 %; ±0.04 to ±0.5 %","Permissible Input Current For Current Input (Destruction Limit), Max.":"40 mA","Permissible Input Voltage For Voltage Input (Destruction Limit), Max.":"20 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$888.11 – $2,165.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/2397e18454e1b1eefc5d489d564c04db.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=246495&mlfb=6ES7355-2CH00-0AE0"},"ai":{"faq":[{"question":"Where can I buy Siemens 6ES7355-2CH00-0AE0?","answer":"The 6ES7355-2CH00-0AE0 is available to order through independent distribution.
