Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 6ES7422-1BL00-0AA0 is a Siemens SM 422 digital output module for the S7-400 programmable logic controller platform, providing 32 digital outputs rated at 0.5 A each with a Profibus interface for integration into the rack-based backplane. It operates on a 24 V DC supply, measures 290 x 25 x 210 mm, weighs 600 g, and is rated IP20 for installation in a protected control cabinet on a rack-mount backplane. This module switches 32 digital outputs, each capable of 0.5 A continuous current, with a minimum load resistance of 48 Ω and a maximum of 4 kΩ. The signal-1 voltage at the output is L+ minus 0.3 V, ensuring a clean ON-state voltage drop. Switching times are symmetrical at 1 ms for both turn-on and turn-off, making it suitable for moderate-speed discrete control tasks such as valve actuation, contactor drives, and indicator banks. The module communicates over Profibus, relying on the S7-400 CPU for program execution and diagnostics. ## Applications The SM 422 digital output module is used in Siemens S7-400-based automation systems for medium-to-large process and manufacturing lines — chemical batch plants, power generation auxiliaries, water treatment skids, and material handling systems — where a high density of 32 discrete outputs per slot is needed to drive solenoids, motor starters, and status indicators.","metaTitle":"Siemens 6ES7422-1BL00-0AA0 SM 422 digital output module, 32 outputs","metaDescription":"Siemens SM 422 digital output module 6ES7422-1BL00-0AA0: 32 outputs, 0.5 A per channel, Profibus, IP20, rack-mount, 24 V DC supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Digital Output Modules"],"specifications":{"Depth":"210 mm","Width":"25 mm","Height":"290 mm","Lower Limit":"48 Ω","Upper Limit":"4 kΩ","For Uprating":"Yes; possible (only outputs of the same group)","Shielded, Max.":"1 000 m","Weight, approx.":"600 g","lifecycle_stage":"mature","\"0\" To \"1\", Max.":"1 ms","\"1\" To \"0\", Max.":"1 ms","Power loss, typ.":"4 W","Rated value (DC)":"24 V","Unshielded, Max.":"600 m","On Lamp Load, Max.":"10 Hz","up to 40 °C, max.":"4 A","up to 60 °C, max.":"2 A; 8 adjacent outputs each","Between The Channels":"No","Diagnostics function":"No","For Signal \"1\", Min.":"L+ (-0.3 V)","Isolation tested with":"500 V AC/707 V DC, type test","Response threshold, typ.":"0.7 to 1.5 A","Short-circuit protection":"Yes; Clocked electronically","Number of digital outputs":"32","With Inductive Load, Max.":"0.5 Hz","With Resistive Load, Max.":"100 Hz","For Signal \"1\" Rated Value":"0.5 A","Controlling a digital input":"Yes; possible","For Redundant Control Of A Load":"Yes; possible (only outputs of the same group)","from backplane bus 5 V DC, max.":"200 mA","Between The Channels, In Groups Of":"32","permissible range, lower limit (DC)":"20.4 V","permissible range, upper limit (DC)":"28.8 V","For Signal \"0\" Residual Current, Max.":"0.3 mA","Between The Channels And Backplane Bus":"Yes","For Signal \"1\" Permissible Range, Max.":"0.6 A","For Signal \"1\" Permissible Range, Min.":"5 mA","from load voltage L+ (without load), max.":"30 mA","Limitation of inductive shutdown voltage to":"-27 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$166.66 – $360.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/cf53aff0606bc4589e989bbfc906e2c7.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=365063&mlfb=6ES7422-1BL00-0AA0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7422-1BL00-0AA0/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7422-1BL00-0AA0","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/6ES7422-1BL00-0AA0 when reusing this data.
