Allen Bradley 1783-US8T Stratix 2000 Unmanaged Ethernet Switch

Product Description

The 1783-US8T is an unmanaged Ethernet switch from Allen Bradley's Stratix 2000 series. It provides eight copper Ethernet ports for connecting compatible network devices without requiring managed switch configuration. The switch supports DIP switch-controlled broadcast storm protection and includes status indicators for checking operating conditions. Its specified operating temperature range is -10 to 60 deg C.

Hardware Specifications

Ethernet Connectivity and Network Protection

The eight copper Ethernet ports allow the switch to connect controllers, operator interfaces, and other Ethernet-capable equipment within a local industrial network, provided the connected devices use compatible interfaces. As an unmanaged switch, the 1783-US8T does not require routine configuration through a managed-switch interface.

The DIP switch-controlled broadcast storm protection feature provides a means to enable or configure the documented protection function. Broadcast storms can consume network bandwidth when excessive broadcast traffic circulates through a network. Confirm the DIP switch settings and protection behavior against the applicable product documentation before commissioning.

Power Supply and Installation Conditions

The switch accepts AC or DC input within the specified ranges. Before connecting the supply, verify the available voltage and frequency against the applicable input type. The stated 24 V nominal rating should not be interpreted as the only permitted input voltage because the supplied specifications also list wider AC and DC ranges.

The IP20 enclosure rating identifies a level of protection against access to hazardous parts and solid objects. It does not indicate protection against water ingress. Select an installation location that meets the specified ambient temperature range and provides suitable environmental protection for the equipment.
