Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 3RK3221-1AA10 is a Siemens 3RK32-series safety-related expansion module, configured as 2/4 F-DI 1/2 F-RO (fail-safe digital inputs and relay outputs). It is rated IP20 for in-cabinet use, mounts on DIN rail, and terminates via screw-type terminals. The module is rated for a shock of 15g / 11 ms and carries a pollution degree of 3, suiting it for industrial environments with moderate vibration and contamination. The 15g / 11 ms shock rating indicates the module can withstand mechanical shocks common in machine-mounted or conveyor-adjacent installations without losing safety integrity. The finger-safe touch protection and 300 V insulation voltage support safe handling during maintenance. The 3RK3221-1AA10 belongs to the Siemens 3RK32 expansion module family, designed for distributed safety I/O in machine safety systems. It is typically specified alongside.","metaTitle":"Siemens 3RK3221-1AA10 Safety Expansion Module, 15g Shock, IP20","metaDescription":"Siemens 3RK3221-1AA10 safety-related expansion module, 2/4 F-DI 1/2 F-RO, 15g / 11 ms shock, IP20, DIN-rail, screw terminals.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Safety Relays"],"specifications":{"Depth":"124 mm","Width":"22.5 mm","Height":"102 mm","at 24 V":"2 A","at 230 V":"2 A","2-Channel":"0","Safety-Related":"4","Single Channel":"2","Type Of Voltage":"DC","lifecycle_stage":"current","Fastening Method":"DIN rail","Product Category":"Modular Safety System","Shock Resistance":"15g / 11 ms","Mounting Position":"vertical","Monitored Start-Up":"Yes","Non-Safety-Related":"0","Product Brand Name":"SIRIUS","Degree Of Pollution":"3","protection class IP":"IP20","Design Of The Product":"2/4 F-DI 1/2 F-RO","EMERGENCY OFF function":"Yes","according to IEC 61508":"3","according to IEC 62061":"3","Parameterizable Outputs":"Yes","Safety-Related 2-Channel":"0","Protective Door Monitoring":"Yes","Evaluation: Enabling Switch":"Yes","Evaluation: Selector Switch":"Yes","Substance Prohibitance (Date)":"05/01/2012","Type Of Electrical Connection":"screw-type terminals","Insulation Voltage Rated Value":"300 V","category according to EN 954-1":"4","Relative Humidity During Operation":"10 ... 95 %","Evaluation: Two-Hand Operator Panel":"Yes","Surge Voltage Resistance Rated Value":"4 000 V","category according to EN ISO 13849-1":"4","due to burst according to IEC 61000-4-4":"2 kV (power ports)","reference code according to IEC 81346-2":"K","Touch Protection Against Electrical Shock":"finger-safe","control supply voltage 1 at DC rated value":"24 V","performance level (PL) according to ISO 13849-1":"e","vibration resistance according to IEC 60068-2-6":"5 ... 500 Hz: 0.75 mm","PFHD with high demand rate according to EN 62061":"3.79E-9 1/h","Evaluation: Electro-Sensitive Protective Equipment":"Yes","electrostatic discharge according to IEC 61000-4-2":"4 kV contact discharge / 8 kV air discharge","Number Of Outputs For Testing Contact-Based Sensors":"2","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Design Of The Fuse Link For Short-Circuit Protection Of Non-Solid-State Switching Element Required":"NH Typ 3NA, DIAZED Typ 5SB, NEOZED Typ 5SE"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$292.61","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/1f6af927e590b8ac6ddd9f53a7f8f69e.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=90163&mlfb=3RK3221-1AA10"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RK3221-1AA10","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/3RK3221-1AA10 when reusing this data.
