The expanded temperature range variant supports 24 V DC to 230 V AC on the field side, making it a fit for mixed-voltage cabinets where a single module must switch both DC solenoids and AC contactors. ## Contact ratings and mechanical life The relay contacts are rated for 300,000 mechanical cycles. Under load, the cycle count derates: 300,000 cycles at 24 V DC / 2 A, 200,000 cycles at 120 V AC / 3 A, and 100,000 cycles at 230 V AC / 3 A. For a valve bank switching at 1 Hz, that 100,000-cycle ceiling at 230 V AC translates to roughly 28 hours of continuous cycling before the contacts wear out — plan the maintenance interval accordingly. The module draws 125 mA from the L+ supply and 40 mA from the 5 V DC backplane bus. Power dissipation is 3.2 W typical — within the S7-300 rack's thermal budget for a mixed I/O slot. ## Physical fit and connector requirement The module occupies a single S7-300 slot at 40 mm wide, 125 mm tall, and 120 mm deep. It requires a 40-pin front connector (sold separately) for field wiring. The relay outputs are isolated in groups of one channel per group via optocouplers, with 2,000 V AC isolation tested between channels and the backplane bus.","metaTitle":"Siemens 6ES7322-1HF80-0AA0 SM 322, 8 Relay Outputs, EOL","metaDescription":"Siemens 6ES7322-1HF80-0AA0 SIMATIC S7-300 SM 322 digital output module, 8 relay outputs, 24-230V AC/DC, 5A, expanded temp range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Output Modules"],"specifications":{"Depth":"120 mm","Width":"40 mm","Height":"125 mm","Shielded, Max.":"1 000 m","Weight, approx.":"320 g","lifecycle_stage":"eol_hot","Mechanical, Max.":"10 Hz","Power loss, typ.":"3.2 W","Unshielded, Max.":"600 m","On Lamp Load, Max.":"2 Hz","up to 60 °C, max.":"5 A","Isolation tested with":"2 000 V AC","Required Front Connector":"40-pin","Number of digital outputs":"8; Relays","With Inductive Load, Max.":"3 A; 3 A (230 V DC), 2 A (24 V AC)","With Resistive Load, Max.":"8 A; 8 A (230 V DC), 5 A (24 V AC)","from supply voltage L+, max.":"125 mA","from backplane bus 5 V DC, max.":"40 mA","Number of operating cycles, max.":"300 000; 300 000 (24 V DC, at 2 A); 200 000 (120 V AC, at 3 A); 100 000 (230 V AC, at 3 A)","Between The Channels, In Groups Of":"1","permissible range, lower limit (AC)":"24 V","permissible range, lower limit (DC)":"24 V","permissible range, upper limit (AC)":"230 V","permissible range, upper limit (DC)":"120 V","Between The Channels And Backplane Bus":"Yes; Optocoupler"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=211407&mlfb=6ES7322-1HF80-0AA0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7322-1HF80-0AA0/alternatives.json"},"ai":{"faq":[{"question":"Does the 6ES7322-1HF80-0AA0 need a 40-pin front connector?","answer":"Yes, the module requires a 40-pin front connector for field wiring, which is ordered separately."},{"question":"What voltage does 6ES7322-1HF80-0AA0 output?","answer":"The relay outputs are potential-free contacts; the module itself does not output a voltage.
