Product Overview

The 1783-ETAP2F is a specialized industrial networking module from Allen-Bradley designed to bridge copper and fiber optic Ethernet segments within an EtherNet/IP™ ecosystem. This device functions as a high-performance tap, featuring one 10/100 Mbps RJ45 copper port and two 100Base-FX fiber optic ports. It is engineered to facilitate Device Level Ring (DLR) topologies, allowing users to connect non-DLR devices to a high-availability ring or to extend network distances across fiber media.

By utilizing fiber optic interfaces, the 1783-ETAP2F provides total electromagnetic immunity, making it an essential component for high-interference environments where standard copper cabling would fail. Its compact, DIN-rail mountable form factor is optimized for industrial control panels, providing a ruggedized solution for media conversion and network expansion.

Industrial Networking and Media Conversion

The 1783-ETAP2F excels in distributed I/O applications where remote field locations are separated by significant distances. Because fiber optic cabling does not conduct electricity, this tap is ideal for connecting buildings or equipment with different grounding potentials, effectively eliminating ground loop risks.

Setup is streamlined through the use of Logix Designer software or a web-based interface, providing comprehensive diagnostics including port status and fiber link quality. The module supports both full and half-duplex operations, ensuring compatibility with a wide range of legacy and modern Ethernet hardware. Whether used to add redundancy to a critical control loop or to shield a network from heavy motor noise, the 1783-ETAP2F provides the deterministic performance and physical resilience required for 24/7 manufacturing and process operations.
