It accepts a broad input window—85 to 264 VAC or 88 to 300 VDC—and delivers two regulated outputs: 5 VDC at up to 10 A and 24 VDC at 1 A, enabling separate rails for central logic supply and the rack's distribution network. The R suffix denotes redundancy, and Siemens documents guidance to install two PS 407 power-supply modules in the rack (typically in slots 1 and 3) to ensure uninterrupted operation and automatic handover in the event of a failure. This specific variant is identified by order number 6ES7407-0KR00-0AA0 and is part of the S7-400 automation system module lineup. It is designed for mounting in standard SIMATIC S7-400 racks and is commonly paired with a second PS 407 module to form a redundant supply that supports ongoing operation during maintenance or a fault.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New Surplus No Box","offer_id":46268590194922,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6es7407-0kr00-0aa0-programmable-logic-controller-module","provider":"GTG Hardware","version":"1.0","type":"link"}
