It also detects wire-break and missing load voltage, which on a refrigeration line means you catch a failed heater or unpowered defrost valve before the evaporator ices up. Short-circuit protection is electronic and per-channel, so a shorted field device does not take down the whole group of 8 outputs. The inductive shutdown voltage is clamped to L+ (-45 V), which limits the back-EMF spike when switching relay or contactor coils.","metaTitle":"Siemens 6ES7322-8BF80-0AB0 SM 322 Digital Output Module","metaDescription":"Siemens 6ES7322-8BF80-0AB0 SM 322 digital output module for S7-300, 8 outputs, 24V DC, 0.5A, with diagnostics and short-circuit protection.","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","Wire-break":"Yes","Short-circuit":"Yes","Shielded, Max.":"1 000 m","Weight, approx.":"210 g","lifecycle_stage":"eol_hot","Diagnostic alarm":"Yes; channel by channel","Power loss, typ.":"5 W","Rated value (DC)":"24 V","Unshielded, Max.":"600 m","On Lamp Load, Max.":"100 Hz","up to 60 °C, max.":"2 A","For Signal \"1\", Min.":"L+ (-0.8 to -1.6 V)","Missing Load Voltage":"Yes","Isolation tested with":"500 V DC","Required Front Connector":"20-pin","Short-circuit protection":"Yes; Electronic","Number of digital outputs":"8","With Inductive Load, Max.":"2 Hz","With Resistive Load, Max.":"100 Hz","from backplane bus 5 V DC, max.":"70 mA","Between The Channels, In Groups Of":"8","For Signal \"1\" Minimum Load Current":"10 mA","permissible range, lower limit (DC)":"20.4 V","permissible range, upper limit (DC)":"28.8 V","For Signal \"0\" Residual Current, Max.":"0.5 mA","Between The Channels And Backplane Bus":"Yes; Optocoupler","from load voltage L+ (without load), max.":"90 mA","Limitation of inductive shutdown voltage to":"L+ (-45 V)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$372.11","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=419207&mlfb=6ES7322-8BF80-0AB0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7322-8BF80-0AB0/alternatives.json"},"ai":{"faq":[{"question":"Does 6ES7322-8BF80-0AB0 have diagnostics and short-circuit protection?","answer":"Yes.
