  • 5-port unmanaged switch connects multiple Ethernet devices
  • Broadcast storm protection at 20 packets per second on 10 Mbps ports
  • Higher 200 packets per second threshold on 100 Mbps ports
  • Low 2-watt power draw at 24 V AC/DC
  • Wide 18–60 V DC and 18–30 V AC input range

Industrial 5-Port Ethernet Switch

The Allen-Bradley Stratix 2000 1783-US5T is an unmanaged switch with five RJ45 ports for connecting multiple Ethernet devices in automation environments. It operates on a 24 V Class 2/SELV supply accepting 18 to 60 V DC or 18 to 30 V AC at 50 to 60 Hz and dissipates a maximum of two watts. Broadcast storm protection triggers at twenty packets per second at ten Mbps or two hundred packets per second at one hundred Mbps per port. Isolation is rated at thirty volts continuous with basic insulation.

Wiring and Power Requirements

DC connections require 0.75 to 2.5 mm² twisted-pair copper wire rated for thirty degrees Celsius above ambient. The in-rush current reaches 2.2 amperes, so the upstream supply and fusing must handle that peak. No accessories, software licences or configuration cables are included in the factory-sealed package.

DIN-Rail Mounting and Temperature Limits

The unit is designed for DIN-rail installation inside a suitable enclosure; allow adequate airflow to keep the surrounding temperature within the rated operating range. Common issues are undersized power supplies that sag under the in-rush current and wiring that exceeds the 2.5 mm² maximum or falls below the minimum temperature rating. Verify the supply voltage stays inside 18 to 60 V DC or 18 to 30 V AC before applying power.

Questions about this item

Will the 0.75 to 2.5 mm² twisted-pair copper power cables need periodic replacement?

The cables are rated for 30 °C above ambient; inspect them during routine maintenance and replace if insulation shows heat damage or cracking.

At what traffic level does the 200 packets-per-second broadcast storm threshold at 100 Mbps become the limiting factor?

Sustained broadcast traffic above 200 packets per second on any 100 Mbps port triggers storm control, which then limits further forwarding on that port.

How much heat does the 2 W maximum dissipation add to a cabinet running continuously?

The switch dissipates up to 2 W at 24 V, contributing minimal heat; ensure the enclosure provides enough airflow for the total installed load.
