Lamp loads are limited to 30 W on DC and 200 W on AC — a practical ceiling for pilot lights and indicator banks. The module has no internal short-circuit protection; an external fuse or breaker must be provided per channel group. Switching times are 10 ms max for both turn-on and turn-off. Diagnostic alarm output is available for monitoring. The relay coil isolation between different circuits is tested at 750 V AC for 1 minute. ## Approvals and Compliance Coverage The module carries cULus, CE, UL, CSA, FM, KC, RCM (C-TICK), and marine approvals — a global compliance set that covers most industrial, marine, and hazardous-location installations without additional certification work. ## Mechanical Fit and Wiring Unshielded cable runs up to 150 m are permitted; shielded runs up to 500 m. The plastic housing withstands a 0.3 m drop five times in its packaging.","metaTitle":"Siemens 6ES7222-1HF32-0XB0 S7-1200 SM 1222, 8 Relay Outputs","metaDescription":"Siemens 6ES7222-1HF32-0XB0 S7-1200 SM 1222 digital output module: 8 relay outputs, 10 A per common at ≤50 °C, switching 5-250 V AC / 5-30 V DC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Digital Output Modules"],"specifications":{"Max.":"70 °C","Min.":"-40 °C","Depth":"75 mm","Width":"45 mm","cULus":"Yes","Height":"100 mm","CE mark":"Yes","Plastic":"Yes","FM approval":"Yes","KC approval":"Yes","UL approval":"Yes","CSA approval":"Yes","In Groups Of":"2","Shielded, Max.":"500 m","Marine approval":"Yes","Weight, approx.":"190 g","lifecycle_stage":"current","\"0\" To \"1\", Max.":"10 ms","\"1\" To \"0\", Max.":"10 ms","Diagnostic alarm":"Yes","Power loss, typ.":"4.5 W","Rated value (AC)":"5 V AC to 250 V AC","Rated value (DC)":"5 V DC to 30 V DC","Unshielded, Max.":"150 m","Fall height, max.":"0.3 m; five times, in product package","On Lamp Load, Max.":"30 W with DC, 200 W with AC","up to 50 °C, max.":"10 A; Current per mass","Between The Channels":"Relays","RCM (formerly C-TICK)":"Yes","IP degree of protection":"IP20","Number of relay outputs":"8","Storage/transport, max.":"1 080 hPa","Storage/transport, min.":"660 hPa","Required Front Connector":"Yes","Short-circuit protection":"No; to be provided externally","For Status Of The Outputs":"Yes","Number of digital outputs":"8","With Inductive Load, Max.":"2 A","With Resistive Load, Max.":"2 A","Between Different Circuits":"750 V AC for 1 minute","For Signal \"1\" Rated Value":"2 A","from load voltage L+, max.":"11 mA/relay coil","Vertical Installation, Max.":"50 °C","Vertical Installation, Min.":"-20 °C","Horizontal Installation, Max.":"60 °C","Horizontal Installation, Min.":"-20 °C","Permissible Temperature Change":"5°C to 55°C, 3°C / minute","from backplane bus 5 V DC, max.":"120 mA","Number of operating cycles, max.":"mechanically 10 million, at rated load voltage 100 000","Between The Channels, In Groups Of":"2","permissible range, lower limit (DC)":"20.4 V","permissible range, upper limit (DC)":"28.8 V","Between The Channels And Backplane Bus":"1 500 V AC for 1 minute","Rated supply voltage of relay coil L+ (DC)":"24 V","Operation at 25 °C without condensation, max.":"95 %"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$88.90 – $216.32","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/33d520486d5400af5daa6ff5c939699f.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=278953&mlfb=6ES7222-1HF32-0XB0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7222-1HF32-0XB0/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7222-1HF32-0XB0","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/6ES7222-1HF32-0XB0 when reusing this data.
