Rated 24 VDC with a signal '1' threshold of 13 to 30 V and a typical input current of 10 mA per channel, it handles 2-wire sensors directly and includes channel-by-channel wire-break and short-circuit detection. The input filter is parameterizable in four steps — 0.5, 3, 15, or 20 ms — letting you match debounce time to the sensor type and cycle rate on the line. ## Diagnostics and fault handling Diagnostic functions — including group error (SF red LED), channel fault indicator (F red), diagnostic alarm, and hardware interrupt — are all parameterizable, so the module reports exactly what the control logic needs. Isolation between different circuits is tested at 75 V DC / 60 V AC; between channels and the backplane bus there is no isolation, so adjacent channels share the same reference. Power loss is 3.5 W typical, and the module draws up to 180 mA from the 5 V DC backplane bus. Dimensions are 175 mm wide, 180 mm high, and 110 mm deep; when screw-mounted the width increases to 180 mm, height to 174 mm, and depth decreases to 90 mm. Unshielded signal lines can run up to 30 m; the module includes RUN LED, FREEZE and SYNC capabilities for coordinated data acquisition across the network.","metaTitle":"Siemens 6ES7141-1BF40-0AB0 Digital Input Module, 8 DI","metaDescription":"Siemens 6ES7141-1BF40-0AB0 digital input module, 8 inputs, PROFIBUS DP slave, 24 VDC, parameterizable diagnostics, channel-by-channel wire-break and","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Input Modules"],"specifications":{"Depth":"110 mm; 90 when screw mounted","Width":"175 mm; 180 when screw mounted","title":"6ES7141-1BF40-0AB0","Height":"180 mm; 174 when screw mounted","RUN LED":"Yes","Wire-break":"Yes; channel by channel","PROFIBUS DP":"Yes","description":"***Spare part*** SIMATIC DP, distributed I/O ET200X:basic module BM141/ECOFAST RS485; 8DE DC 24V, 5-pol., M12, Channel diagnostics, short circuit and wire break, Hardware interrupts Input delay time: 0,5ms/3ms/15ms/20ms","2-Wire Sensor":"Yes","Short-circuit":"Yes; channel by channel","For Signal \"0\"":"-3 to +5V","For Signal \"1\"":"13 to 30V","Parameterizable":"Yes; 0.5 / 3 / 15 / 20 ms","SYNC capability":"Yes","Weight, approx.":"650 g","lifecycle_stage":"current","Diagnostic alarm":"Yes; Parameterizable","Power loss, typ.":"3.5 W","Rated value (DC)":"24 V","Unshielded, Max.":"30 m; for signal lines","FREEZE capability":"Yes","Number of outputs":"8","PROFIBUS DP slave":"Yes","Hardware interrupt":"Yes; Parameterizable","up to 40 °C, max.":"1 A","up to 55 °C, max.":"8","Between The Channels":"No","Diagnostics function":"Parameterizable","For Signal \"1\", Typ.":"10 mA","Group error SF (red)":"Yes","Isolation tested with":"500 V DC","Transmission rate, max.":"12 Mbit/s; 9,6 / 19,2 / 45,45 / 93,75 / 187,5 / 500 kbit/s; 1,5 / 12 Mbit/s","Number of digital inputs":"8; 8 process channels DI, single channel connector","Short-circuit protection":"Yes; Electronic","Between The Load Voltages":"No","Between Different Circuits":"75 V DC/60 V AC","Channel fault indicator F (red)":"Yes","Diagnostic information readable":"Yes","from backplane bus 5 V DC, max.":"180 mA","Number of expansion modules, max.":"7","Of Which Pneumatic Interfaces, Max.":"6","Between The Channels And Backplane Bus":"No","Status indicator digital input (green)":"Yes","Of Which Motor Starters/Frequency Converters, Max.":"6","Direct data exchange (slave-to-slave communication)":"Yes; Sender","Permissible Quiescent Current (2-Wire Sensor), Max.":"1.5 mA","between PROFIBUS DP and all other circuit components":"Yes","Between Load Voltage And All Other Switching Components":"No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$284.61","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/eaa2d09cb181f4f534f179bc0da588d0.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=250972&mlfb=6ES7141-1BF40-0AB0"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7141-1BF40-0AB0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/6ES7141-1BF40-0AB0 when reusing this data.
