It's designed to power the logic side of a safety relay or a small safety controller, not a field actuator bank. The 0.6 A rated output current is enough for the 24 V bus of one or two safety modules; expect the internal power loss at 17 W to be dissipated into the enclosure air, so leave breathing space in a densely packed panel. The 22.5 mm width and 100 mm height match the standard SIRIUS safety relay footprint; depth is 121.6 mm, which is shallow enough to clear most gland plates. Spring-loaded push-in terminals accept solid 1x (20-16 AWG) or 2x (20-16 AWG) and stranded 1x (20-16 AWG) or 2x (20-16 AWG). Mount in any position. ## Protection and environment Enclosure is IP20 — protected against solid objects >12.5 mm, no water ingress rating. That is fine for a dry cabinet; not for washdown zones. Shock resistance 10g / 11 ms. Relative humidity 10-95% non-condensing. ## Output and diagnostics Output is short-circuit proof and galvanically isolated from the input — a fault on the 24 V side won't propagate back to the AC line. The green LED lights when 24 V is present. Input operates on AC or DC across 0.85-1.1 x rated voltage, so it holds regulation through a 10% brownout. Surge voltage resistance at 4 kV and insulation voltage rated 300 V.","metaTitle":"Siemens 3SK1230-2AW20 SIRIUS Safety Power Supply, 24 V / 0.6","metaDescription":"Siemens 3SK1230-2AW20 SIRIUS safety power supply, 24 V DC / 0.6 A output, 110-240 V AC/DC input, IP20, push-in terminals, active production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Safety Relays"],"specifications":{"Depth":"121.6 mm","Solid":"1x (20 ... 16), 2x (20 ... 16)","Width":"22.5 mm","at DC":"0.85 ... 1.1","Height":"100 mm","Stranded":"1x (20 ... 16), 2x (20 ... 16)","at 50 Hz":"0.85 ... 1.1","at 60 Hz":"0.85 ... 1.1","During Storage":"-40 ... +80 °C","power loss [W]":"17 W","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting","Product Category":"Safety relays","Shock Resistance":"10g / 11 ms","Mounting Position":"any","at DC rated value":"110 ... 240 V","Product Brand Name":"SIRIUS","Degree Of Pollution":"3","Product Designation":"Power supply","Overvoltage Category":"3","at 50 Hz rated value":"110 ... 240 V","at 60 Hz rated value":"110 ... 240 V","Type Of Current Supply":"24 V / 0,6 A","Consumed Current Maximum":"0.25 A","EMC emitted interference":"IEC 60947-5-1, Class A","With Core End Processing":"1x (0.5 ... 1.0 mm²), 2x (0.5 ... 1.0 mm²)","Output Current Rated Range":"0.6 A","Without Core End Processing":"1x (0.5 ... 1.5 mm²), 2x (0.5 ... 1.5 mm²)","Type Of Electrical Connection":"spring-loaded terminal (push-in)","Insulation Voltage Rated Value":"300 V","output voltage at DC rated value":"24 V","Design Of Short-Circuit Protection":"automatically start-up","Relative Humidity During Operation":"10 ... 95 %","air pressure according to SN 31205":"900 ... 1 060 hPa","Display Version For Normal Operation":"Green LED for 24 V OK","Surge Voltage Resistance Rated Value":"4 000 V","protection class IP of the enclosure":"IP20","Property Of The Output Short-Circuit Proof":"Yes","Galvanic Isolation Between Input And Output":"Yes","Product Feature Parallel Switching Of Channels":"No","Required Spacing For Grounded Parts At The Side":"5 mm","vibration resistance according to IEC 60068-2-6":"5 ... 500 Hz: 0.75 mm","Installation Altitude At Height Above Sea Level Maximum":"4 000 m; Derating, see Product Notification 109792701","Required Spacing With Side-By-Side Mounting At The Side":"0 mm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/3SK1230-2AW20/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3SK1230-2AW20 and how do I get a price?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
