1783-USP16T Allen‑Bradley Ethernet switches

Product Detailed Description

The Allen-Bradley 1783-USP16T is an unmanaged Ethernet switch from the Stratix 2000 series, manufactured by Rockwell Automation. It is designed for simple, plug-and-play connectivity in industrial control systems, providing reliable Ethernet networking without the need for configuration or management software. This switch features 16 copper RJ45 ports supporting 10/100 Mbps speeds, making it suitable for small to medium-sized networks in harsh environments. It supports both AC and DC power inputs and includes features like broadcast storm protection to enhance network stability. The 1783-USP16T is a functional replacement for the discontinued 1783-US16T model, offering improved power flexibility and certifications for global use. It operates in an open-style enclosure and is built to withstand extreme temperatures, ensuring robust performance in industrial settings.

Product Parameters (Specifications)

The following table summarizes the key technical specifications of the 1783-USP16T:

These parameters ensure compatibility with standard industrial Ethernet protocols and provide isolation for safety in powered environments.

Product Advantages

• Ease of Use: As an unmanaged switch, it requires no setup or IT expertise—simply connect and operate, ideal for non-technical users in manufacturing settings.
• Rugged Industrial Design: Wide temperature range and high humidity tolerance make it reliable in extreme conditions, reducing downtime compared to commercial switches.
• Cost-Effective Networking: Provides high port density (16 ports) at a lower cost than managed alternatives, with built-in broadcast storm protection to prevent network overloads.
• Flexible Power Options: Supports both AC and DC inputs, allowing seamless integration into diverse power infrastructures without additional converters.
• Enhanced Safety and Compliance: Features electrical isolation and hazardous location certifications, minimizing risks in explosive or volatile environments.
• Backward Compatibility: Direct replacement for older models like 1783-US16T, with improved power handling for future-proofing small networks.

Precautions and Notes

• Installation Safety: Disconnect all power sources before wiring or mounting. Use only certified tools and follow ESD (electrostatic discharge) precautions to avoid damage to ports or internals.
• Power Supply: Ensure input voltage stays within 16–60V DC or 18–30V AC limits to prevent overheating or failure. Use Class 2 or SELV-rated supplies only; non-compliance may void certifications.
• Environmental Limits: While rated for -40°C to +70°C, avoid direct exposure to corrosive substances or excessive vibration. Mount on a DIN rail in a well-ventilated area to dissipate the 6.72 W heat.
• Wiring Guidelines: Ground the device properly using 14 AWG wire at 1.82 N·m torque. Limit cable lengths to 100 m per port for optimal performance; use shielded twisted-pair (STP) cables in noisy environments.
• Configuration: The SW1 DIP switch enables/disables broadcast storm protection—default is enabled. SW2 is reserved; do not alter. No firmware updates are supported due to unmanaged design.
• Hazardous Areas: In Class I Division 2 locations, ensure proper conduit sealing and consult local codes. The device is not intrinsically safe.
• Maintenance: Periodically inspect for dust buildup on ports. If issues arise (e.g., port failures), power cycle the unit; contact Rockwell support for diagnostics.
• General Warning: Read the full user manual (publication 1783-UM002) before use. Improper handling may lead to equipment damage or safety hazards.

Product Applications

The 1783-USP16T is optimized for industrial automation and control systems where simple, reliable Ethernet connectivity is essential. Typical applications include:

• Machine-Level Networking: Connecting PLCs, HMIs, sensors, and I/O modules in packaging, material handling, or assembly lines for real-time data exchange.
• Small Control Panels: Deployed in electrical enclosures for linking multiple devices in water/wastewater treatment or HVAC systems.
• Harsh Environment Setups: Used in oil & gas, mining, or food & beverage processing where extreme temperatures and humidity are common, thanks to its robust ratings.
• Distributed I/O Networks: Facilitating communication in conveyor systems or robotic cells, supporting up to 8K MAC addresses for scalable growth.
• Legacy System Upgrades: As a drop-in replacement for older unmanaged switches, enhancing reliability in retrofit projects without network redesign.
