About the Allen-Bradley 1761-NET-ENI

The 1761-NET-ENI is a MicroLogix and SLC communication adapter, now discontinued (user manual 1761-UM006). It runs from 24V dc, 20.4 to 26.4V dc, drawing 50 mA typical and 100 mA maximum, with a maximum inrush of 200 mA. Internal isolation is 710V dc for one minute, and it works from 0°C to +60°C at 5% to 95% relative humidity, non-condensing.

What is the 1761-NET-ENI used for?

It connects a MicroLogix or SLC controller's RS-232 port to an Ethernet network. Its immunity ratings cover both the RS-232 and Ethernet connections.

Lifecycle and successor

Discontinued (Rockwell Automation lifecycle status, checked 25 October 2026).
