Product Overview

The Allen-Bradley 1783-US6T2F is an industrial-grade Stratix 2000™ unmanaged Ethernet switch engineered for reliable, plug-and-play connectivity on the plant floor. This module features a total of eight communication ports: six 10/100 Mbps copper RJ45 ports and two Small Form-factor Pluggable (SFP) slots. The inclusion of SFP slots allows for high-performance fiber-optic uplinks, enabling long-distance data transmission and providing immunity to electromagnetic interference in dense automation environments.

Designed for simplicity and resilience, this switch requires no software configuration, making it an ideal solution for expanding local area networks (LANs) to include Programmable Logic Controllers (PLCs), Human-Machine Interfaces (HMIs), and variable frequency drives. Its compact footprint and ruggedized housing ensure stable network performance in areas where space is limited and environmental conditions are harsh.

Advanced Hardware Features

• Flexible Fiber Connectivity: The dual SFP slots permit the use of various 100 Mbps SFP transceivers, allowing engineers to tailor the network to specific distance and fiber-type requirements.

• Rugged Environmental Rating: Built for extreme industrial temperatures, the 1783-US6T2F operates reliably from -40°C to 70°C, ensuring network uptime in non-climate-controlled control cabinets.

• Broadcast Storm Protection: Features integrated hardware circuitry to prevent network congestion caused by broadcast traffic, maintaining the integrity of time-critical automation data.

• Visual Diagnostics: Front-facing LED indicators provide immediate status updates for power health, link status, and data activity for each individual port.

• Low-Maintenance Operation: As an unmanaged switch, it eliminates the need for IT-level management or IP addressing for the switch itself, reducing commissioning time and maintenance overhead.

Industrial Network Integration

The 1783-US6T2F serves as a foundational bridge within EtherNet/IP™ architectures. It effectively distributes data between various automation assets while providing the physical durability required for factory floor deployment. The module is fully compatible with any standard Ethernet-enabled equipment, making it a versatile choice for discrete manufacturing, water/wastewater, and energy infrastructure applications.
