Product Overview

The Allen-Bradley 1784-U2DN cable offers a simple USB connection to a DeviceNet network. It measures 0.61 meters in length. The cable supports three data rates: 125, 250, and 500 kbps. It features auto-detection of the active network rate. A manual switch sets the fallback rate to 125 kbps. The device includes a node address selector for network identification. Status LEDs show blue and red for module, network, self-test, and standby modes. The USB host interface provides 5 VDC at 75 mA. The DeviceNet side requires 24 VDC at 75 mA. Power consumption is 0.5 W. The enclosure meets IP20 protection. It is certified with C-Tick, CE, KC, and UL standards. This cable is designed for industrial environments.

Application Scenarios

Technicians use this cable to connect a computer to a DeviceNet network. It is ideal for programming PLCs and configuring drives. The cable allows real-time monitoring of DeviceNet nodes. It simplifies network diagnostics and troubleshooting. Use it during system commissioning or maintenance. The flexible data rate settings adapt to different network speeds. The node address selector helps assign unique IDs. This cable works with Rockwell Automation and other DeviceNet-compatible devices. It is a handy tool for field engineers and system integrators.
