Siemens 6ES7407-0KA02-0AA0 PLC Control Module

Siemens PS407 power supply module for the SIMATIC S7-400 automation system, model 6ES7407-0KA02-0AA0, delivers 5 V DC at up to 10 A from a 120/230 V AC mains input. Built to slot into an S7-400 rack, it provides the centralized 5 V rail that powers the rack backplane, CPU, and I/O modules, supporting stable operation of the control system. This 0KA02 variant is the PS407 10 A version, with related configurations such as 6ES7407-0KR02-0AA0 listed in Siemens’ PS407 family. Key specifications include a wide-range input of 120–230 V AC and a 5 V DC output rated for 10 A continuous supply. Typical applications include industrial automation tasks where a dedicated 5 V DC power source is required to support S7-400 controllers and their field devices. When selecting, verify compatibility with your S7-400 rack and ensure the combined 5 V rail load remains within the module’s rated capacity.
