Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 6ES7422-1HH00-0AA0 is a Siemens SM 422 digital output module for the SIMATIC S7-400 system, providing 16 relay outputs rated at 5 A per channel across a 5..230 V AC or 1..60 V DC range. The module draws 4.5 W from the backplane, occupies a 25 mm slot width, and is classified as Size 5 per NEMA. RoHS compliance dates from 01-03-08. Each of the 16 relay outputs switches up to 5 A continuous at 230 V AC (resistive) or 60 V DC. The relay contacts are rated for 100 000 electrical cycles under AC-15 or DC-13 loads, and 3 000 000 mechanical cycles — a figure that governs maintenance intervals in high-duty applications. Each channel has a per-channel status LED for quick fault isolation on the cabinet door. Digital input control is possible, allowing the module to be read back for diagnostics, though no onboard diagnostics block is implemented. ## Applications This SM 422 relay output module is used in SIMATIC S7-400 racks to switch AC or DC loads such as contactors, solenoid valves, motor starters, and indicator lamps in industrial machine control, conveyor systems, and process skids. The 16 isolated channels suit applications requiring galvanic separation between the PLC backplane and field devices.","metaTitle":"Siemens 6ES7422-1HH00-0AA0 SM 422 Digital Output Module, 16 Relay DO","metaDescription":"Siemens SM 422 digital output module 6ES7422-1HH00-0AA0: 16 relay outputs, 5 A per channel, 5..230 V AC, 4.5 W, 25 mm wide, RoHS since 01-03-08.","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","For Uprating":"No; Not possible","Shielded, Max.":"1 000 m","Weight, approx.":"700 g","lifecycle_stage":"mature","Mechanical, Max.":"20 Hz","Power loss, typ.":"4.5 W","Rated value (AC)":"230 V","Rated value (DC)":"60 V","Unshielded, Max.":"600 m","On Lamp Load, Max.":"1 Hz","up to 40 °C, max.":"10 A; 10 A with fan subassembly","up to 60 °C, max.":"5 A; 10 A with fan subassembly","Between The Channels":"Yes","Diagnostics function":"No","Isolation tested with":"1 500 V AC","Short-circuit protection":"No","Number of digital outputs":"16; Relays","With Inductive Load, Max.":"5 A; 5 A (30 V DC), 5 A (230 V AC)","With Resistive Load, Max.":"5 A; 5 A (30 V DC), 5 A (230 V AC), 1.2 A (60 V DC), 0.2 A (125 V DC)","For Signal \"1\" Rated Value":"5 A","Controlling a digital input":"Yes; possible","For Redundant Control Of A Load":"Yes; Possible (only outputs with the same load voltage)","from backplane bus 5 V DC, max.":"1 A","Number of operating cycles, max.":"100 000; 100 000 (AC-15 / DC-13); 3 000 000 mechanical","Thermal continuous current, max.":"5 A","Between The Channels, In Groups Of":"2","For Signal \"1\" Minimum Load Current":"11 mA","permissible range, lower limit (AC)":"2 V","permissible range, lower limit (DC)":"1 V","permissible range, upper limit (AC)":"264 V","permissible range, upper limit (DC)":"60 V","Between The Channels And Backplane Bus":"Yes","Status indicator digital output (green)":"Yes; per channel","Size of motor starters according to NEMA, max.":"Size 5 according to NEMA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$500.39 – $1,267.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/1b04b9561970e8ae7d946719ca97f5c2.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=322752&mlfb=6ES7422-1HH00-0AA0"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7422-1HH00-0AA0","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/6ES7422-1HH00-0AA0 when reusing this data.
