About the Allen-Bradley 1783-US5T

The 1783-US5T is a Stratix 2000 5T port unmanaged switch, now discontinued. Its power input is 24V (12…48V DC, 18...30V AC, 50/60 Hz, SELV), and it uses 3.4 W. It is open-style, rated IP30, and works from -10 °C to +60 °C. The 1783-USP5T is named by the maker as the successor (Functional Replacement).

What is the 1783-US5T used for?

It connects a few Ethernet devices in a control panel without configuration. Nominal current is 180 mA on DC and 360 mA on AC, and both power and communication ports carry immunity ratings.

Lifecycle and successor

Discontinued (Rockwell Automation lifecycle status, checked 24 October 2026).

OEM successor: 1783-USP5T
