It uses one 5‑pin screw-terminal block for the DeviceNet connection (CAN_H, CAN_L, Drain\/Shield, +24 VDC, 0 VDC) and fits as a 1-slot, standard 1756 module. Baud rates are software-selectable among 125 Kbps, 250 Kbps and 500 Kbps, with corresponding maximum network lengths of up to 500 m, 250 m and 100 m respectively. The module’s typical backplane power draw is about 400 mA at 5.1 V, with no required backplane current at 24 V, and it is designed for 0 °C to 60 °C environments (IP20 when mounted in an enclosure). Supported configuration tools include RSNetWorx for DeviceNet and Studio 5000\/RSLogix 5000 with Add‑On Profiles for Generic Device support. Firmware Revision 3.010 is current for the 1756‑DNB, as noted in Rockwell release documentation. The 1756-DNB is UL Listed, cULus, CE and ODVA‑conformant, and it supports a variety of DeviceNet devices such as sensors, actuators, and other I\/O devices in industrial automation, making it a common choice for integrating DeviceNet devices with ControlLogix systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658947428654,"sku":null,"price":275.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_21f3d827-bc3c-4d78-9bc1-408f8b35043c.jpg?v=1769525810","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-dnb-a-ser-a-f-w-rev-3-010-devicenet-communication-module","provider":"PLG Automation ","version":"1.0","type":"link"}
