Allen-Bradley 1783-US8T Ethernet Switch
The Allen-Bradley 1783-US8T, also cataloged as the 1783-US8T Unmanaged Switch, operates as a dedicated hardware component for physical Ethernet signal distribution and packet switching within Allen-Bradley Stratix 2000 industrial networks. It provides plug-and-play network expansion across 8 Fast Ethernet copper ports, routing unmanaged data traffic between control controllers, human-machine interfaces, and field devices.

Deterministic Network Behavior & Broadcast Storm Protection
The 1783-US8T switch maintains low latency and deterministic network data throughput across control cabinet installations. Integrated DIP-switch-controlled broadcast storm protection suppresses high-volume multicast and broadcast frames, preventing network degradation during traffic spikes. Advanced hardware-level filtering ensures clean frame processing, preventing backplane bus communication velocity bottlenecks when interfacing with EtherNet/IP deterministic networks.
Frequently Asked Questions
Q: How is broadcast storm protection activated on the 1783-US8T?
A: Broadcast storm protection is enabled or disabled via onboard hardware DIP switches located on the switch housing, requiring no software configuration.
Q: What power input voltage range is accepted by the 1783-US8T power terminals?
A: The switch accepts dual power source options, supporting 12 to 48 VDC or 18 to 30 VAC at 50/60 Hz.
Field Installation Guidelines
- DIN Rail Mounting: Snap the 1783-US8T securely onto a standard 35 mm DIN rail inside an IP54 or higher rated protective enclosure to protect against dust and moisture.
- Ethernet Cabling: Connect shielded Category 5e (or higher) twisted-pair Ethernet cables to the 8 copper RJ45 ports. Maintain maximum cable lengths under 100 meters per segment.
- Power Terminals and Grounding: Wire the supply voltage to the removable terminal block. Connect the chassis ground terminal directly to the enclosure single-point ground bus to protect against electromagnetic noise.
