About the Allen-Bradley 1783-ETAP1F

The 1783-ETAP1F is a 3 port EtherNet/IP tap with 2 copper ports and 1 fiber port, now discontinued (technical data 1783-TD002). It runs from 24V DC (20.4…27.6V DC), drawing up to 200 mA and 4.8 W. The fiber port is 100Base-FX IEEE802.3u at 1310 nm with an LC connector, for 62.5/125 µm and 50/125 µm multimode fiber up to 2 km. The 1783-ETAP1T2SFP is named by the maker as the successor (Engineering Replacement).

What is the 1783-ETAP1F used for?

It connects a device to an EtherNet/IP network and links copper and fiber runs, for distances copper cannot cover. Copper ports use RJ45 connectors with Category 5e minimum cable. The power terminal takes a torque of 0.6…0.8 Nm.

Lifecycle and successor

Discontinued (Rockwell Automation lifecycle status, checked 24 October 2026).
