The description flags it as a spare part, so this is the replacement unit for an existing field installation, not a new-design pick. ## Input voltage range and signal thresholds Signal '0' is recognised between -3 and +5 V; signal '1' between 13 and 30 V. That 13 V threshold is typical for 24 V DC sensor inputs — it gives noise margin below the nominal 24 V rail. The module also accepts 2-wire sensors, with a permissible quiescent current up to 1.5 mA. ## Diagnostics and interrupt handling Channel-by-channel wire-break and short-circuit detection are standard, with a red channel fault LED per input. A parameterisable diagnostic alarm and hardware interrupt feed the PLC — useful for catching a broken sensor lead on a conveyor line before the cycle faults out. The input delay is selectable at 0.5, 3, 15, or 20 ms, matching the response to the sensor type and process speed. ## Power draw and isolation Typical power loss is 1.5 W from the backplane bus, with a max draw of 30 mA at 5 V DC. Isolation between circuits is tested at 500 V DC, and between different circuits at 75 V DC / 60 V AC. There is no potential separation between the digital inputs themselves — adjacent channels share a common reference. ## Sourcing reality — spare part channel This is a current-production spare part according to Siemens lifecycle data. No direct stock-holding claim; the lead time depends on the quantity and the channel at that moment.","metaTitle":"Siemens 6ES7141-1BF30-0XB0 EM141 8DI 24V DC, Spare Part","metaDescription":"Siemens 6ES7141-1BF30-0XB0 spare part for ET 200X. 8 digital inputs 24V DC, M12, channel diagnostics, wire-break & short-circuit detection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Input Modules"],"specifications":{"Depth":"55 mm","Width":"87 mm; Width module 60 mm","title":"6ES7141-1BF30-0XB0","Height":"110 mm","Wire-break":"Yes; channel by channel","description":"***Spare part*** SIMATIC DP, distributed I/O ET 200X: Extended module EM141, 8 DE 24 V DC, 5-pole, 4xM12, 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","Weight, approx.":"250 g","lifecycle_stage":"current","Diagnostic alarm":"Yes; Parameterizable","Power loss, typ.":"1.5 W","Rated value (DC)":"24 V","Unshielded, Max.":"30 m","Number of outputs":"4","Hardware interrupt":"Yes; Parameterizable","up to 40 °C, max.":"0.5 A; Total current: 0.9 A","up to 55 °C, max.":"8","Diagnostics function":"Yes; Parameterizable","For Signal \"1\", Typ.":"10 mA","Group error SF (red)":"Yes","Isolation tested with":"500 V DC","Number of digital inputs":"8","Short-circuit protection":"Yes; Electronic","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.":"30 mA","Potential separation digital inputs":"No","Status indicator digital input (green)":"Yes","Permissible Quiescent Current (2-Wire Sensor), Max.":"1.5 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"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=26836&mlfb=6ES7141-1BF30-0XB0"},"ai":{"faq":[{"question":"What diagnostic features does 6ES7141-1BF30-0XB0 support?","answer":"Channel-by-channel wire-break and short-circuit detection, a parameterisable diagnostic alarm, a hardware interrupt, and a red channel fault LED per input.
