It requires the 40-pin front connector (sold separately) and fits a 40 mm wide slot in the S7-300 rack. This is a high-density module — 32 points in a single-wide footprint — so it's common in larger I/O cabinets where panel space is tight. ## Output ratings and signal integrity Each channel sources 0.5 A rated current, with a maximum of 2 A per channel at 40 °C and 3 A at 60 °C — note the derating direction: the module can actually deliver more current at higher ambient, which is unusual and suggests the thermal limit is set by the internal silicon junction, not the PCB copper. The response threshold for short-circuit protection is 1 A typ, and the protection is electronic (no fuse to replace). Switching times are 100 µs from 0 to 1 and 500 µs from 1 to 0. That's fast enough for most discrete control signals but not for high-speed pulse trains — the maximum resistive load switching frequency is 100 Hz, and with inductive loads it drops to 0.5 Hz. On lamp loads (high inrush), the limit is 10 Hz. The module has no diagnostics — no diagnostic alarm, no wire-break detection, no short-circuit indicator per channel. The only status feedback is the signal-level voltage at the output: for a logic 1, the output is L+ minus 0.8 V minimum. Channel-to-channel isolation is provided, and isolation is tested at 500 V DC.","metaTitle":"Siemens 6ES7322-1BL00-0AA0 32-DO Digital Output Module","metaDescription":"Siemens 6ES7322-1BL00-0AA0 SIMATIC S7-300 digital output module, 32 outputs, 24 V DC, 0.5 A per channel, 40-pin front connector.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Output Modules"],"specifications":{"Depth":"120 mm","Width":"40 mm","title":"6ES7322-1BL00-0AA0","Alarms":"No","Height":"125 mm","Wire-break":"No","Lower Limit":"48 Ω","Upper Limit":"4 kΩ","description":"SIMATIC S7-300, Digital output SM 322, isolated, 32 DO, 24 V DC, 0.5A, 1x 40-pole, Total current 4 A/group (16 A/module)","For Uprating":"No","Short-circuit":"No","Shielded, Max.":"1 000 m","Weight, approx.":"260 g","lifecycle_stage":"eol_hot","\"0\" To \"1\", Max.":"100 µs","\"1\" To \"0\", Max.":"500 µs","Diagnostic alarm":"No","Power loss, typ.":"6.6 W","Rated value (DC)":"24 V","Unshielded, Max.":"600 m","On Lamp Load, Max.":"10 Hz","up to 40 °C, max.":"2 A","up to 60 °C, max.":"3 A","Fuse OK FSG (green)":"No","Between The Channels":"Yes","Diagnostics function":"No","For Signal \"1\", Min.":"L+ (-0.8 V)","Group error SF (red)":"No","Missing Load Voltage":"No","Isolation tested with":"500 V DC","Required Front Connector":"40-pin","Response threshold, typ.":"1 A","Short-circuit protection":"Yes; Electronic","Number of digital outputs":"32","With Inductive Load, Max.":"0.5 Hz","With Resistive Load, Max.":"100 Hz","For Signal \"1\" Rated Value":"0.5 A","Controlling a digital input":"Yes","Rated load voltage PWR (green)":"No","Channel fault indicator F (red)":"No","Diagnostic information readable":"No","For Redundant Control Of A Load":"Yes; only outputs of the same group","from backplane bus 5 V DC, max.":"110 mA","Between The Channels, In Groups Of":"8","For Signal \"1\" Minimum Load Current":"5 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","Status indicator digital output (green)":"Yes; per channel","from load voltage L+ (without load), max.":"160 mA","Limitation of inductive shutdown voltage to":"L+ (-53 V)","for signal \"1\" permissible range for 0 to 40 °C, max.":"0.6 A","for signal \"1\" permissible range for 0 to 40 °C, min.":"5 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$203.20","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/484d9e3cf2ebb8468f52665f8d458d54.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=253844&mlfb=6ES7322-1BL00-0AA0"},"ai":{"faq":[{"question":"Does the 6ES7322-1BL00-0AA0 have a 40-pin connector?","answer":"Yes, the module requires a 40-pin front connector (sold separately).
