Allen Bradley Stratix 2000 1783-US05T 5-Port Unmanaged Fast Ethernet Switch

Technical Overview

The 1783-US05T (Part Number 1783-US05T) is a compact, entry-level industrial Ethernet switch designed to provide reliable connectivity for machine-level networks. As part of the Stratix 2000 portfolio, this unmanaged device offers a "plug-and-play" solution for expanding copper port density without the need for complex software configuration or IP management. It is specifically engineered to operate in harsh industrial environments, featuring a rugged housing and a wide input voltage range that supports both AC and DC power sources.

With its broadcast storm protection and auto-negotiation capabilities, the module ensures efficient data flow between PLCs, HMIs, and other networked automation components. Its small footprint makes it an ideal choice for space-constrained control panels where basic, high-speed switching is required.

• Small-scale star topology networks for material handling and assembly line equipment.

• Integration into systems requiring flexible power inputs from existing 24V DC or 24V AC control transformers.

Technical FAQ

Does this unit require any software for setup? No, the device is an unmanaged switch. It functions immediately upon power-up and connection to the network with no configuration required.

How does this module handle different device speeds? Each port independently auto-negotiates the highest possible speed (10 or 100 Mbps) and duplex mode supported by the connected end device.

Is this switch compatible with EtherNet/IP protocols? Yes, while it does not support advanced features like IGMP Snooping found in managed switches, it is fully capable of transporting standard EtherNet/IP traffic for basic automation tasks.
