The 2 A rating covers the common control loads: contactors, solenoid valves, signal lamps, and small motor starters. The relay outputs provide galvanic isolation between channels, so a short on one output won't cascade into the adjacent circuit. ## Railway-grade build with EN 50155 certification This is the SIPLUS variant, meaning it carries EN 50155 certification for rolling stock and trackside equipment — sections 4, 5, and 12, covering temperature class T1, category 1, class A/B. The standard S7-300 SM 322 relay output module (6ES7322-1HH01-0AA0) lacks this certification and the extended temperature range. The -40 to 70 °C operating range is the key differentiator from the standard 0 to 60 °C industrial module. For a BOM going into a rail application or a cold-climate installation, this is the part that stays within spec without a heater or derating. ## Current production, sourced per RFQ The module requires a 20-pin front connector (sold separately). The 40 mm width fits a single S7-300 slot; the 125 mm height and 120 mm depth match the standard S7-300 envelope, so it swaps into an existing rack without re-spacing. ## Approvals and compliance for global installs CE, UL (File E239877), KC, EAC, and RCM approvals are on file — the module clears for European, North American, Korean, Eurasian, and Australian markets without additional certification work. Isolation tested at 1 500 V AC between channels and the backplane bus. The 4.5 W typical power loss stays within the S7-300 rack budget; the 1 000 m shielded cable length gives headroom for distributed I/O in a railcar or plant floor layout.","metaTitle":"Siemens 6AG1322-1HH01-2AA0 Digital Output Module, 16 Relay","metaDescription":"Siemens 6AG1322-1HH01-2AA0 digital output module with 16 relay outputs, 2 A per channel, -40 to 70 °C range, EN 50155 railway certified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Output Modules"],"specifications":{"Max.":"70 °C","Min.":"-40 °C","Depth":"120 mm","Width":"40 mm","title":"6AG1322-1HH01-2AA0","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)","Fuse blown":"No","Wire-break":"No","KC approval":"Yes","UL approval":"Yes; File E239877","description":"SIPLUS S7-300 SM 322-20-pole based on 6ES7322-1HH01-0AA0 with conformal coating, -40…+70 °C, digital output optically isolated 16 DQ, relay contacts","For Uprating":"No","Short-circuit":"No","Shielded, Max.":"1 000 m","Weight, approx.":"250 g","lifecycle_stage":"current","Diagnostic alarm":"No","Mechanical, Max.":"10 Hz","Power loss, typ.":"4.5 W","Rated value (AC)":"230 V","Rated value (DC)":"120 V","Unshielded, Max.":"600 m","On Lamp Load, Max.":"1 Hz","up to 40 °C, max.":"8 A","up to 60 °C, max.":"8 A","Fuse OK FSG (green)":"No","Between The Channels":"Yes","Diagnostics function":"No","Missing Load Voltage":"No","EAC (formerly Gost-R)":"Yes","Isolation tested with":"1 500 V AC","RCM (formerly C-TICK)":"Yes","Required Front Connector":"20-pin","Short-circuit protection":"No","Number of digital outputs":"16; Relays","With Inductive Load, Max.":"2 A; 2 A (230 V AC), 2 A (24 V DC)","With Resistive Load, Max.":"2 A; 2 A (230 V AC), 2 A (24 V DC)","For Signal \"1\" Rated Value":"2 A","Controlling a digital input":"Yes","from supply voltage L+, max.":"250 mA","Contact connection (internal)":"No","Rated load voltage PWR (green)":"No","For Redundant Control Of A Load":"Yes","from backplane bus 5 V DC, max.":"100 mA","Number of operating cycles, max.":"100 000; 50 000 (24 V DC, at 2 A); 700 000 (120 V AC, at 2 A); 100 000 (230 V AC, at 2 A)","Thermal continuous current, max.":"2 A","Between The Channels, In Groups Of":"8","For Signal \"1\" Minimum Load Current":"10 mA","Between The Channels And Backplane Bus":"Yes; Optocoupler","Status indicator digital output (green)":"Yes","Rated supply voltage of relay coil L+ (DC)":"24 V","Installation altitude above sea level, max.":"2 000 m","Size of motor starters according to NEMA, max.":"Size 5 according to NEMA","Ambient air temperature-barometric pressure-altitude":"Tmin ...
