A regulated 24 V supply minimizes voltage sag during high‑density I\/O updates, ensuring predictable scan timing under varying load conditions. When deployed in redundant configurations, ORing behavior maintains uninterrupted backplane power, preventing communication dropouts during supply switchover. The module’s electrical profile aligns with firmware flash compatibility requirements for controllers that depend on stable DC input during update cycles.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1606‑XL240DR operate with DC input A: Yes.

Ensure manual AC range selection matches the supply voltage before energizing. Provide adequate ventilation when operating above 60 deg C due to derating requirements. Use proper strain relief on DC output wiring to prevent connector stress. Verify grounding and bonding practices to minimize noise coupling into PLC backplanes.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":48214670901438,"sku":"1606-XL240DR","price":450.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/allen-bradley-1606-xls240e-performance-power-supply-e43eejvcca2.png?v=1759047054","url":"https:\/\/www.autooiltech.com\/products\/1606-xl240dr-allen-bradley-redundant-power-supply","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
