It accepts Pt 100 RTDs and thermocouple types B, E, J, K, R, and S — covering the vast majority of industrial temperature sensing from cryogenic to 1700 °C furnace work. The module draws its power from a 24 VDC supply (rated value 24 V) and dissipates up to 6.9 W, so budget that thermal load into the rack's ventilation — especially if the adjacent slots are also high-power analog or CPU modules. ## Input flexibility — RTD, thermocouple, and millivolt Each of the 8 channels can be configured for voltage (0 to +10 V), current (0 to 20 mA, 4 mA to 20 mA), or resistance measurement (240 Ω to 4 kΩ), with the thermocouple and Pt 100 ranges handled directly without external signal conditioners. The module also reads bipolar signals: -1.75 V to +11.75 V and -3.5 mA to +23.5 mA, making it usable for process transmitters that swing below zero on fault conditions. For thermocouple wiring, the maximum shielded cable run is 200 m, dropping to 50 m when using 80 mV range or thermocouple inputs — keep the cold-junction compensation reference junction close to the module for best accuracy. ## Lifecycle reality — EOL hot stage For a replacement path, evaluate the S7-1500-based temperature control modules (e.g., ET 200SP AI 8xRTD/TC) if a platform migration is feasible; otherwise, source this exact unit against your RFQ through our network. Digital inputs accept 24 VDC signals with a '1' threshold of 13 to 30 V and typical draw of 7 mA per input. The module supports logic links and is fully parameterizable via the S7-300 configuration tool.","metaTitle":"Siemens 6ES7355-2SH00-0AE0 FM 355-2S, 8 AI TC/RTD, EOL","metaDescription":"Siemens 6ES7355-2SH00-0AE0 FM 355-2S temperature control module. 8 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","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 20 mA":"Yes","Lower Limit":"240 Ω","Upper Limit":"4 kΩ","0 to 23.5 mA":"Yes","Thermocouple":"Yes","2-Wire Sensor":"Yes","4 mA to 20 mA":"Yes","For Signal \"0\"":"-3 to +5V","For Signal \"1\"":"13 to 30V","Shielded, Max.":"200 m; 50 m at 80 mV and thermocouples","For Logic Links":"Yes","Parameterizable":"Yes","Weight, approx.":"470 g","lifecycle_stage":"eol_hot","Power loss, max.":"6.9 W","Power loss, typ.":"5.5 W","Rated value (DC)":"24 V","Unshielded, Max.":"600 m","For Thermocouples":"Type B, E, J, K, R, S","On Lamp Load, Max.":"100 Hz","up to 60 °C, max.":"400 mA","-1.75 V to +11.75 V":"Yes","-3.5 mA to +23.5 mA":"Yes","Between The Channels":"No","For Signal \"1\", Min.":"L+ (-2.5 V)","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 digital inputs":"8","Required Front Connector":"2x 20-pin","Short-circuit protection":"Yes; Electronic","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","Number of digital outputs":"8","With Inductive Load, Max.":"0.5 Hz","With Resistive Load, Max.":"100 Hz","For Resistance Thermometer":"Pt100 (standard)","For Signal \"1\" Rated Value":"0.1 A","Controlling a digital input":"Yes","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","For Signal \"0\" Residual Current, Max.":"0.5 mA","Between The Channels And Backplane Bus":"Yes; Optocoupler","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 %","from load voltage L+ (without load), max.":"270 mA; typ. 220 mA","Limitation of inductive shutdown voltage to":"L+ (-1.5 V)","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 %","for signal \"1\" permissible range for 0 to 60 °C, max.":"150 mA","for signal \"1\" permissible range for 0 to 60 °C, min.":"5 mA","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":"$768.10 – $1,872.00","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=387808&mlfb=6ES7355-2SH00-0AE0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7355-2SH00-0AE0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the 6ES7355-2SH00-0AE0?","answer":"This module is sourced to order against an RFQ through our independent distribution network.
