Its 9 slots and dual redundant power supply option fit a mid-size I\/O extension; pick the larger extension rack instead when more signal-module slots are needed in a single expansion.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eBecause the ER2 takes only signal modules, it is the rack to add when a central S7-400 rack has run out of I\/O slots but still has spare communication or CPU capacity. The two redundant power supply positions keep the added I\/O powered if one supply fails, useful where the added signal modules serve process-critical measurements. At 257.5 mm wide it fits alongside the central rack in the same cabinet section without extra mounting depth.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":53960580333851,"sku":"6ES7403-1JA01-0AA0","price":630.06,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/siemens-6es7403-1ja01-0aa0-er2-plc-rack.png?v=1789782002","url":"https:\/\/stoklink.com\/products\/siemens-6es7403-1ja01-0aa0-er2-9-slot-plc-rack","provider":"Stoklink","version":"1.0","type":"link"}
