Allen-Bradley 1783-US4T1F Stratix 2000 Unmanaged Ethernet Switch

Product Overview

The Allen-Bradley 1783-US4T1F functions as a high-velocity industrial networking hub within the Stratix 2000 family. This unmanaged switch expands local area networks (LAN) in rugged environments by providing four copper Fast Ethernet ports and one preinstalled multimode fiber SFP module. It offers a "plug-and-play" solution for engineers needing to bridge long-distance fiber runs with localized copper-based automation hardware. We supply this unit as 100% Brand New and Original, ensuring your network maintains maximum uptime without the risks of used equipment.

Technical Specifications

The 1783-US4T1F utilizes an open-style enclosure and supports versatile power inputs for global compatibility.

Engineering Advantages

• Hybrid Connectivity: The preinstalled SFP module eliminates the need for separate media converters. It allows the switch to transmit data over multimode fiber, bypassing the 100-meter limit of standard copper cabling while providing total immunity to electromagnetic interference (EMI).

• Flexible Power Railing: The internal circuitry accepts both DC (12–48V) and AC (18–30V) power. This flexibility allows engineers to integrate the switch into standard PLC power loops or machine-tool AC control circuits without adding dedicated power supplies.

• Ultra-Compact Footprint: With a width of only 1.17 inches, this switch fits into extremely narrow cabinet spaces. It maximizes DIN rail density, allowing more room for I/O modules and safety relays.

• Simplified Deployment: As an unmanaged switch, the 1783-US4T1F requires zero software configuration. It automatically negotiates speed and duplex settings, reducing commissioning time for field technicians.

FAQs

• Does this unit require a separate SFP purchase?

  No. The 1783-US4T1F comes with a preinstalled multimode fiber SFP module. You can connect your fiber optic LC connectors directly to the unit out of the box.

• What type of fiber cable should I use with this switch?

  This model utilizes a multimode fiber SFP. For optimal performance and distance, use standard 50/125 or 62.5/125 micron multimode fiber optic cabling.

• How should I ground the device for high-noise environments?

  Use 14 AWG (2.5 mm²) copper wire for the ground connection. Ensure the wire is rated for at least 187 °F (86 °C) and use a suitable ring terminal to secure the connection to the ground screw.

• Can this switch handle both 24V DC and 24V AC?

  Yes. The power terminal accepts 12–48V DC or 18–30V AC. This makes it ideal for older facilities that primarily use AC control power or modern DC-standard panels.
