About the Allen-Bradley 1783-ETAP

The 1783-ETAP is an EtherNet/IP tap with 3 copper ports, now discontinued. It runs from 24V DC (20.4 to 27.6V DC) CL 2/SELV, drawing up to 125 mA at 24V DC and 3 W. It works from -25 to +70 °C in an open-style housing. The 1783-ETAP3T is named by the maker as the successor (Functional Replacement).

What is the 1783-ETAP used for?

It connects a device to a copper EtherNet/IP network, over RJ45 connectors with 2- or 4-pair Category 5e minimum cable. The DC power terminal takes one 0.33 to 3.3 mm2 wire, at a screw torque of 0.6 to 0.8 Nm.

Lifecycle and successor

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

OEM successor: 1783-ETAP3T
