The outputs switch 120/230 V AC loads (permissible range 79 V to 264 V AC) and include zero-crossing switching at 60 V, which reduces inrush stress on the connected load. Maximum switching frequency is 10 Hz with resistive loads and 0.5 Hz with inductive loads; on lamp loads the limit is 1 Hz. ## Diagnostics and channel isolation The module supports parameterizable diagnostic alarms and a group error SF (red) LED. Each channel is isolated from the others in groups of 1, with optocoupler isolation between channels and the backplane bus. Isolation is tested at 1,500 V AC. The module requires an external 40-pin front connector (not included) and external short-circuit protection via a 3.15 A / 250 V quick-response fuse. ## Panel fit and power budget The module occupies a 40 mm wide slot in a Siemens S7-300 DIN rail assembly, with dimensions of 125 mm height and 120 mm depth. It draws a maximum of 100 mA from the 5 V DC backplane bus and dissipates 8.6 W typ. Unshielded cable runs up to 600 m and shielded runs up to 1,000 m are supported.","metaTitle":"Siemens 6ES7322-5FF00-0AB0 SM322, 8 DO, 2 A, 120/230 V AC","metaDescription":"Siemens 6ES7322-5FF00-0AB0 SM322 digital output module, 8 channels, 2 A per channel, 120/230 V AC, with diagnostics.","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","For Uprating":"No","Shielded, Max.":"1 000 m","Weight, approx.":"275 g","lifecycle_stage":"eol_hot","Diagnostic alarm":"Yes; Parameterizable","Power loss, typ.":"8.6 W","Rated value (AC)":"230 V; 120/230 V AC","Unshielded, Max.":"600 m","On Lamp Load, Max.":"1 Hz","up to 40 °C, max.":"4 A","up to 60 °C, max.":"4 A","Between The Channels":"Yes","Diagnostics function":"Yes; Parameterizable","For Signal \"1\", Min.":"L1 (-8.5 V)","Group error SF (red)":"Yes","Zero-crossing switch":"Yes; 60 V","Isolation tested with":"1 500 V AC","Required Front Connector":"40-pin","Short-circuit protection":"Yes; to be provided externally; fuse 3.15 A / 250 V, quick response","Number of digital outputs":"8","With Inductive Load, Max.":"0.5 Hz","With Resistive Load, Max.":"10 Hz","For Signal \"1\" Rated Value":"2 A","Controlling a digital input":"Yes","For Redundant Control Of A Load":"Yes","from backplane bus 5 V DC, max.":"100 mA","Between The Channels, In Groups Of":"1","For Signal \"1\" Minimum Load Current":"10 mA","permissible range, lower limit (AC)":"79 V","permissible range, upper limit (AC)":"264 V","For Signal \"0\" Residual Current, Max.":"2 mA","Between The Channels And Backplane Bus":"Yes; Optocoupler","Status indicator digital output (green)":"Yes","from load voltage L1 (without load), max.":"2 mA","For Signal \"1\" Permissible Surge Current, Max.":"20 A; with 2 half waves","Size of motor starters according to NEMA, max.":"Size 5 according to NEMA","for signal \"1\" permissible range for 0 to 40 °C, max.":"2 A","for signal \"1\" permissible range for 0 to 40 °C, min.":"10 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$314.96 – $662.00","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=488595&mlfb=6ES7322-5FF00-0AB0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7322-5FF00-0AB0/alternatives.json"},"ai":{"faq":[{"question":"Does 6ES7322-5FF00-0AB0 have diagnostic alarms?","answer":"Yes, the module supports parameterizable diagnostic alarms and a group error SF (red) LED for status indication."},{"question":"Can 6ES7322-5FF00-0AB0 be used with S7-300?","answer":"Yes, this is an S7-300 SM322 digital output module designed for the S7-300 DIN rail system.
