Allen Bradley 1761-NET-ENI MicroLogix Ethernet Interface Module

Product Overview

The Allen Bradley 1761-NET-ENI acts as a powerful communication bridge that enables Ethernet/IP connectivity for controllers utilizing DF1 full-duplex protocols. Primarily designed for the MicroLogix 1000, 1200, and 1500 series, as well as SLC 500 and CompactLogix processors, this module converts serial RS-232 signals into high-speed Ethernet data. It allows legacy hardware to participate in modern networked environments for data collection, programming, and HMI interfacing. We supply this unit as 100% Brand New and Factory Original, providing a reliable, zero-hour solution for critical infrastructure upgrades.

Technical Specifications

The 1761-NET-ENI features industrial-grade isolation and low power consumption to ensure stable network performance:

Engineering Advantages

• Legacy Network Integration: This module instantly upgrades standalone serial controllers to Ethernet-capable nodes. It permits remote programming and data monitoring across the factory floor without replacing existing PLC hardware or rewiring the entire system.

• Robust Electrical Isolation: The 710V DC isolation barrier protects the serial port of your controller from transient voltages and ground loops common in industrial Ethernet networks. This safeguarding prevents processor damage during electrical faults.

• Versatile Mounting Geometry: The compact housing supports both standard 35mm DIN rail and direct panel mounting. This flexibility allows engineers to install the module in high-density control cabinets or onto flat surfaces where rail space remains unavailable.

• High-Impact Resilience: Tested to withstand operating shocks up to 30 G and non-operating panel shocks up to 50 G, the 1761-NET-ENI performs reliably on machinery subject to heavy vibration or mechanical impact.

• Wide Thermal Range: The module operates consistently from 0 to 60 °C, ensuring stable communication in non-climate-controlled plant environments or high-temperature enclosures containing heat-generating drives.

FAQs

• Is this 1761-NET-ENI unit 100% Brand New?

  Yes. We guarantee this interface module is 100% Brand New and arrives in its original factory packaging. Each unit undergoes strict quality inspections to ensure it meets the electrical and physical standards of the original manufacturer.

• Does this module support both AC and DC power?

  The 1761-NET-ENI accepts a power range of 20.4V to 26.4V. While many industrial applications utilize 24V DC, the hardware also supports 24V AC power sources, providing flexibility based on the existing control transformer configuration in your panel.

• Which controllers can I connect to this interface?

  The 1761-NET-ENI connects to any device supporting DF1 full-duplex protocol via an RS-232 port. This includes the entire MicroLogix family, SLC 5/03 and 5/04, and even some non-Rockwell devices that utilize compatible serial communication.

• How do I configure the IP address for this unit?

  You set the IP address using the Allen Bradley BOOTP/DHCP utility or the ENI Configuration Utility software. Once configured, the module retains the static IP address in non-volatile memory.
