It accepts ±10 V signals and digitizes them at 12-bit resolution including sign, with a basic conversion time of 1 ms per channel. The module occupies one slot in an ET 200SP station and draws its 24 V DC supply from the backplane bus, with a typical power loss of 0.6 W. At 10 mm wide, it fits the narrowest slice in the system — useful when panel space is tight and every millimeter of DIN rail counts toward the I/O count. ## Input characteristics and filtering The input resistance is 100 kΩ for the ±10 V range. The destruction limit is 20 V DC continuous or 75 V DC for up to 1 second (duty factor 1:20), so transient protection upstream is still advisable on long cable runs. Digital filtering is parameterizable in four stages to suppress noise on the signal path. The module achieves at least 50 dB crosstalk rejection between inputs at 50/60 Hz and 50 dB common-mode rejection with USS below 2.5 V. Linearity error is ±0.05 % of the input range, temperature drift is ±0.01 %/K, and repeat accuracy at 25 °C is ±0.1 %. These figures keep the measurement stable across the enclosure's thermal gradient.","metaTitle":"Siemens 6ES7123-1FB50-0AB0 Analog Input Module, 2 AI, 12 bit","metaDescription":"Siemens 6ES7123-1FB50-0AB0 analog input module for SIMATIC ET 200SP. 2 inputs, ±10 V, 12-bit resolution, 1 ms conversion, 10 mm wide.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Analog Input Modules"],"specifications":{"Depth":"51 mm","Width":"10 mm","Alarms":"No","Height":"64 mm","Voltage":"Yes","Step: low":"Yes; 8x cycle time","Step: High":"Yes; 128x cycle time","Step: None":"Yes; 1x cycle time","Step: Medium":"Yes; 64x cycle time","-10 V to +10 V":"Yes","Required Slots":"1; from 8","Shielded, Max.":"200 m","Parameterizable":"Yes; parameterizable in 4 stages by means of digital filtering","Weight, approx.":"20 g","lifecycle_stage":"current","Power loss, typ.":"0.6 W","Rated value (DC)":"24 V","Between The Channels":"No","Diagnostics function":"No","Measurement principle":"Actual value encryption","Usable terminal block":"TB 16IM-SC","For Voltage Measurement":"Yes","Number of analog inputs":"2","Basic conversion time (ms)":"1 ms","Reverse polarity protection":"Yes","Resolution (incl. overrange)":"±10 V: 12 bit incl. sign","from supply voltage L+, max.":"30 mA","Between the inputs and MANA (UCM)":"2 V DC / 2 Vpp AC","Input resistance (-10 V to +10 V)":"100 kΩ","Integration time, parameterizable":"No","Crosstalk between the inputs, min.":"50 dB; At 50/60 Hz","Between The Channels And Backplane Bus":"No","Voltage, relative to input range, (+/-)":"0.7 %","Common mode interference (USS < 2.5 V), min.":"50 dB","Linearity error (relative to input range), (+/-)":"0.05 %","Temperature error (relative to input range), (+/-)":"0.01 %/K","Resolution with overrange (bit including sign), max.":"12 bit","Between The Channels And The Power Supply Of The Electronics":"No","Permissible Input Voltage For Voltage Input (Destruction Limit), Max.":"20 V; 20 V DC permanent, 75 V DC for max. 1 s (duty factor 1:20)","Repeat accuracy in steady state at 25 °C (relative to input range), (+/-)":"0.1 %","Series mode interference (peak value of interference < rated value of input range), min.":"70 dB; With smoothing factor k = 128"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$420.62","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=450554&mlfb=6ES7123-1FB50-0AB0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7123-1FB50-0AB0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the Siemens 6ES7123-1FB50-0AB0?","answer":"Submit a request with your target quantity and we will confirm availability and pricing at quote time."},{"question":"Is the 6ES7123-1FB50-0AB0 obsolete?","answer":"No. The lifecycle stage is current — Siemens still produces this module.
