It is a basic DI – no diagnostic alarms, no parameterization, no hardware interrupt – so the slot is reserved for standard binary field signals. ## Footprint for the panel layout Isolation is tested with 500 VDC between the field side and the backplane, consistent with a basic DI of this class.","metaTitle":"Siemens 6AG1321-1BH02-2AA0 SIPLUS SM 321, 16 DI, 24 VDC","metaDescription":"Siemens 6AG1321-1BH02-2AA0 SIPLUS S7-1200 digital input module, 16 channels, 24 VDC, -40 °C to 70 °C, current production, UL/CE/EN 50155.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Input Modules"],"specifications":{"Max.":"70 °C","Min.":"-40 °C","Depth":"120 mm","Width":"40 mm","title":"6AG1321-1BH02-2AA0","Alarms":"No","Height":"125 mm","CE mark":"Yes","EN 50155":"Yes; Sections 4, 5 and 12; no further agreements apply; T1, Category 1, Class A/B, EN 50155:2007 (see SIOS entry 109755985)","KC approval":"Yes","UL approval":"Yes; File E239877","description":"SIPLUS S7-300 SM 321 20-pole based on 6ES7321-1BH02-0AA0 with conformal coating, -40…+70 °C, digital input isolated 16 DI, 24 V DC, 1x 20-pole","2-Wire Sensor":"Yes","For Signal \"0\"":"-30 to +5 V","For Signal \"1\"":"13 to 30V","Shielded, Max.":"1 000 m","Parameterizable":"No","Weight, approx.":"200 g","lifecycle_stage":"current","Diagnostic alarm":"No","Power loss, typ.":"3.5 W","Rated value (DC)":"24 V","Unshielded, Max.":"600 m","Hardware interrupt":"No","up to 40 °C, max.":"16","up to 60 °C, max.":"16; 16 @ > 60 °C","At \"0\" To \"1\", Max.":"4.8 ms","At \"0\" To \"1\", Min.":"1.2 ms","At \"1\" To \"0\", Max.":"4.8 ms","At \"1\" To \"0\", Min.":"1.2 ms","Between The Channels":"No","Diagnostics function":"No","For Signal \"1\", Typ.":"7 mA","EAC (formerly Gost-R)":"Yes","Isolation tested with":"500 V DC","RCM (formerly C-TICK)":"Yes","Type of input voltage":"DC","Number of digital inputs":"16","Required Front Connector":"20-pin","from backplane bus 5 V DC, max.":"10 mA","Between The Channels, In Groups Of":"16","permissible range, lower limit (DC)":"20.4 V","permissible range, upper limit (DC)":"28.8 V","Between The Channels And Backplane Bus":"Yes; Optocoupler","Status indicator digital input (green)":"Yes","Installation altitude above sea level, max.":"5 000 m","Permissible Quiescent Current (2-Wire Sensor), Max.":"1.5 mA","Ambient air temperature-barometric pressure-altitude":"Tmin ...
