140G-J6F3-D25-BA Allen‑Bradley Programmable controller

Product Detailed Description

The Allen-Bradley 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 is a functional replacement for the discontinued 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:

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 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.
