The Allen-Bradley 1747-SN is a remote input/output scanner module that communicates with the 1746 backplane SLC processor. Its compatibility spans across 502, 503, 504, and 505 processors. It helps SLC processors to gain high-speed remote communication to the Allen-Bradley operator interface and control devices. This scanner is used with the universal remote input/output network if the application requires either distributed controllers for each to have I/O communications along with a supervisory controller or connections between I/O adapters and controllers.
