Product Overview
The Allen‑Bradley 1783‑ETAP1F is an industrial EtherNet/IP tap that integrates embedded switch technology directly into a compact, DIN‑rail mountable module. Part of Rockwell Automation’s Stratix family, this device features two 10/100Base‑TX copper RJ45 ports and one 100Base‑FX fiber optic port with an LC multimode connector, effectively functioning as both a managed Layer 2 switch and a media converter in a single unit . The 1783‑ETAP1F is specifically designed to enable single‑port EtherNet/IP devices—such as PLCs, drives, and I/O adapters—to participate in advanced network topologies including linear and Device Level Ring (DLR) configurations, without requiring a separate Ethernet switch .
The embedded switch technology in the Allen‑Bradley 1783‑ETAP1F delivers robust network management capabilities including VLAN (802.1Q), Quality of Service (QoS) (802.1p), IGMP snooping, and support for the IEEE 1588 Precision Time Protocol (PTP), making it ideal for time‑sensitive industrial applications . The 1783‑ETAP1F operates on a 24V DC supply with a maximum power consumption of just 4.8 watts, drawing 200mA at rated voltage . With an industrial operating temperature range of ‑25°C to +60°C and compliance with IP20/open‑style enclosure standards, the Allen‑Bradley 1783‑ETAP1F is built to perform reliably in demanding factory floor environments .

Main Features and Advantages
Embedded Switch Technology for Topology Flexibility: The Allen‑Bradley 1783‑ETAP1F distinguishes itself from simple media converters by integrating a full Layer 2 managed switch into a compact tap form factor. This allows the 1783‑ETAP1F to support Device Level Ring (DLR) and linear topologies, enabling single‑port devices to connect to redundant network architectures without external hardware . The DLR capability ensures a typical recovery time of less than 3 milliseconds for a 50‑node ring, making network failures virtually transparent to connected devices and enabling uninterrupted machine operation in mission‑critical applications .
Hybrid Copper‑to‑Fiber Connectivity with Noise Immunity: The Allen‑Bradley 1783‑ETAP1F bridges copper and fiber network segments, offering complete galvanic isolation through its 100Base‑FX fiber port. This feature makes the 1783‑ETAP1F immune to electromagnetic interference (EMI), ground loops, and voltage transients commonly encountered in industrial environments with welding equipment, variable frequency drives, and high‑power machinery . The fiber interface also extends network distances well beyond the 100‑meter limitation of standard copper Ethernet, making the 1783‑ETAP1F ideal for connecting remote I/O racks or control cabinets separated by long distances.
