About the Allen-Bradley 1747-SN

The 1747-SN is the SLC remote I/O scanner module, with four channels, now discontinued. It draws 600 mA at 5V dc from the backplane, and comm circuit isolation is 500V DC. It works from 0°C to +60°C, is stored at -40°C to +85°C, and takes 5 to 95% humidity without condensation (user manual 1747-UM013). The 5069-AENTR is named by the maker as the successor (Engineering Replacement).

What is the 1747-SN used for?

It lets an SLC 500 controller scan remote I/O over its four channels. Noise immunity is to NEMA Standard ICS 2-230.

Lifecycle and successor

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

OEM successor: 5069-AENTR
