01 / PRODUCT PROFILE

Siemens 6ES7407-0DA02-0AA0 is the SIMATIC S7-400 PS407 wide-range power supply rated for 120 V or 230 V AC/DC input. It supplies the backplane bus with up to 4 A at 5 V DC and up to 0.5 A at 24 V DC without requiring a base load.

02 / INTEGRATION NOTES

The module occupies one S7-400 slot and provides primary-to-secondary isolation, short-circuit protection, and 20 ms mains buffering. A 3.6 V lithium AA backup battery can be installed as an option for the supported rack configuration.

Input protection and conductor selection must match the installation. The official connection description specifies three conductors up to 1.5 mm² with suitable end sleeves, and the input can draw an inrush current up to 8.5 A during the documented 5 ms half-value interval.
