The Siemens 6AG1505-0KA00-7AB0 is a 24 V SELV power supply module rated for 25 W infeed to the backplane bus, with a wide temperature range from -40 °C to 70 °C and conformal coating for harsh environments. It delivers 6.2 W power loss at nominal conditions and includes reverse polarity protection, short-circuit protection, and redundancy capability. The isolation is tested at 707 V DC type test, and it provides base isolation for max 60 V AC/75 V DC.
Key Ratings for Fit
The temperature range is the standout: -40 °C to 70 °C, but note the derating — above +60 °C the maximum power input drops from 25 W to 12.5 W. If you're running in a warm cabinet, factor that in. The supply also handles altitude up to 5 000 m with a temperature derating above 2 000 m. IP20 means it's not sealed against moisture ingress; the conformal coating and protection against fouling (Type 1) and resistance to coolants and lubricants (incl. diesel and oil droplets) make it suitable for dirty environments like machine tool panels or outdoor cabinets with proper enclosure.
