Product Overview

The Siemens 6ES7407-0RA02-0AA0 is a PS 407 series DC power supply module for the SIMATIC S7-400 automation platform. It converts wide-range AC or DC power (120/230 V) to regulated 5 V and 24 V DC outputs, supplying typical control backplane and auxiliary circuits. With a rated 20 A 5 V output, it supports mid- to large-scale CPU and I/O configurations in industrial control systems, including process automation, manufacturing cell power feeds, and high-availability rack installations.
