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 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.


The 1747-SN requires G-file configuration. The streamlining of this configuration is done with RSLogix software. It uses a backplane current load of 600mA at 5V DC. It is compatible with the Belden 9463 cable and it offers noise immunity over different cable lengths dependent on the baud rate. Devices making use of this connection can span a distance of up to 10,000 feet. Its extended node capability facilitates the complementary mode, in which the 1747-SN is able to support connections from up to 32 devices. It can support up to 16 devices in normal mode. The extended node capability can only be used if all the remotely connected devices possess extended node capability. The 1747-SN allows the transfer of large amounts of data without compromising the system throughput.


According to the 1747-SN manual, it can transfer and be configured for up to 4 discrete data logical racks. It communicates with devices in remote locations via the Allen-Bradley Remote Input/Output (RIO) Link. The RIO link is configured to have 1 master device, which is a scanner and manages many slave units called adapters. The 1747-SN can be installed in any slot of the SLC chassis other than Slot 0.
