Product Overview
The Siemens 6ES7405-0DA02-0AA0 is a PS 405 series power supply module designed for the SIMATIC S7-400 automation system. It provides both 24 V DC (up to 0.5 A) and 5 V DC (up to 4 A) outputs for the backplane bus and on-board electronics. It accepts a wide DC input range and offers inrush current handling, overload protection, and power-failure buffering. Integration into S7-400 racks makes it suitable for industrial control cabinets in discrete and process automation environments. Part number 6ES7405-0DA02-0AA0 is the standard 4 A variant.
