Engineering Advantages

• Extended Temperature Performance: This switch operates reliably between -40 and 70 °C. This extreme thermal range eliminates the need for cabinet heaters or cooling fans, allowing for direct installation in outdoor remote terminal units (RTUs) and non-climate-controlled environments.

• Integrated Broadcast Storm Protection: The hardware includes built-in DIP switches to control Broadcast Storm Protection. Activating this feature prevents network traffic congestion from flooding the system, effectively solving communication bottlenecks caused by faulty field devices or network loops.

• Flexible Power Input: The 1783-US16T accepts both AC and DC power inputs within a wide voltage range. This versatility allows engineers to utilize existing cabinet power supplies (from 18V to 60V DC) without adding specialized voltage regulators.

• Rugged DIN Rail Mounting: The compact, metal-housed design supports standard DIN rail mounting. This ensures a vibration-resistant installation that occupies minimal space in crowded control panels, maintaining secure port alignment even in high-impact manufacturing zones.

FAQs

• Is the 1783-US16T supplied as a brand new original unit?

  Yes. We supply this Ethernet switch exclusively as 100% Brand New original stock. It arrives in its original factory packaging, ensuring full compliance with Rockwell Automation’s industrial networking standards.

• Does this unmanaged switch require any software configuration?

  No. The 1783-US16T offers true plug-and-play functionality. You manage the primary hardware settings, such as Broadcast Storm Protection, directly through the integrated physical DIP switches, removing the need for software tools or IP addressing.

• What do the status indicators communicate?

  The integrated LED status indicators provide real-time feedback on power status and individual port link/activity. These visual cues allow technicians to diagnose physical layer cable issues or power failures instantly without specialized network testing equipment.

• Can I use this switch in a Device Level Ring (DLR) topology?

  As an unmanaged switch, the 1783-US16T does not natively support DLR management. However, it functions perfectly as a local distribution point for end-devices branching off from a primary network backbone or within star-topology control architectures.
