USB to DeviceNet Cable | Allen Bradley 1784-U2DN
The Allen Bradley 1784-U2DN is a compact USB-to-DeviceNet interface cable designed to connect a personal computer to a DeviceNet industrial network via a standard USB port. Measuring 0.61 meters in length, this adapter facilitates easy programming, configuration, and network diagnostics, operating with flexible data transmission rates and integrated diagnostic LEDs.
Communication and Configuration
The cable supports communication speeds of 125 kbps, 250 kbps, and 500 kbps, featuring an automatic data rate detection mechanism with a 125 kbps fallback option. It includes a physical data rate switch and a rotary node address selector switch for manual configuration, coupled with multi-color status LEDs for network activity and module monitoring.
Power and Electrical Characteristics
The interface is powered via a 5V DC USB connection drawing 75 mA and an external DeviceNet power supply of 24V DC at 75 mA, maintaining a low total power consumption of 0.5 W. Connection to the network is established using a single 5-pin open-style Phoenix connector.
Physical and Environmental Build
Weighing 0.34 kg, the unit is built for industrial settings with an IP20 enclosure rating. It complies with multiple international standards including C-Tick, CE, KC, and UL, requiring the appropriate device driver installation on the host PC prior to use.
