Siemens 6EP3331-6SB00-0AY0 SITOP LOGO!Power 24V/1.3A DIN Rail Power Supply

The Siemens 6EP3331-6SB00-0AY0 is a LOGO!Power stabilized DIN-rail power supply that converts 100-240 V AC input to a regulated 24 V DC, 1.3 A output. Output voltage is adjustable from 22.2 to 26.4 V via potentiometer, with 86% efficiency and short-circuit-proof constant-current protection. It weighs 0.12 kg and fits a 36 mm DIN-rail footprint.

Selection Notes

The output is adjustable 22.2-26.4 V via potentiometer, useful for compensating cable drop on long DIN-rail runs to LOGO! logic modules or 24 V field devices without adding a separate trim resistor. A 40 ms power-failure buffering time and internal short-circuit protection with a defined 1.7 A constant-current limit let it ride through brief mains dips without nuisance tripping downstream. At 1.3 A rated output it sizes for a single LOGO! base module plus a modest number of 24 V sensors — for larger 24 V loads, a higher-current SITOP or LOGO!Power variant in the same family is the step up.

Applications

Sized for LOGO! logic controller installations and small 24 V DC field-device loads in control cabinets, building automation panels, and machine control boxes.
