It accepts 110–240 V AC (50/60 Hz) or DC input and delivers a regulated 24 V DC at 0.6 A, with galvanic isolation between input and output and an output that is short-circuit proof. The 22.5 mm width means it takes one standard modular position in the enclosure, and it mounts by screw or snap-on in any orientation. The 0.6 A output is the continuous rated current at 24 V DC — sized to power the internal bus of a 3SK1 safety relay or a small safety logic module, not for driving field actuators. Power loss is 17 W, which is heat that must be dissipated inside the enclosure; with a 22.5 mm footprint and no forced cooling, keep ambient below 60 °C and respect the 5 mm side spacing to grounded parts for natural convection. The surge voltage resistance of 4 000 V and overvoltage category 3 confirm it's rated for fixed-installation industrial panels where transients from contactor or motor switching are expected. ## Integration notes Screw terminals accept solid wire 1x (20…14 AWG) or 2x (18…16 AWG), and with ferrules 1x (0.5…2.5 mm²) or 2x (0.5…1.0 mm²). Strip length is the standard 8–10 mm for this terminal class. The green LED lights when 24 V output is present — useful during commissioning to confirm the supply is alive before the safety relay logic is energized. Shock resistance of 10g / 11 ms covers most machine-mounted applications but not high-vibration zones near un-damped presses or crushers.","metaTitle":"Siemens 3SK1230-1AW20 SIRIUS Safety Relay Power Supply, 24V","metaDescription":"Siemens 3SK1230-1AW20 SIRIUS safety relay power supply, 24V DC / 0.6A output.
