Verify that all 24 VDC supply lines match the rated input parameters and maintain correct polarity to prevent triggering internal reverse polarity protection circuits. Separate field power lines from high-voltage AC cables and variable frequency drive outputs to preserve high noise resistance on the plant floor. When attaching the DeviceNet connector, ensure signal wire shielding is properly terminated and grounded according to standard network installation guidelines.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":45319757365363,"sku":"1734-PDN","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/1734-PDN_1200x1200_2873e64c-bf71-47f9-a570-ef4e0329c4df.png?v=1785996682","url":"https:\/\/www.dcssupplier.com\/products\/allen-bradley-1734-pdn-point-i-o-devicenet-adapter-module","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
