Allen-Bradley 1747-SDN Remote I O Scanner Module

The Allen-Bradley 1747-SDN is a DeviceNet remote I/O scanner module for the SLC 500 family that acts as the DeviceNet master to bring field devices onto the controller network. Catalog number 1747-SDN with FRN 4.0 indicates its firmware revision and it exchanges configuration data, device I/O data, and status information with the connected SLC processor. Designed to sit in an SLC 500 remote I/O chassis, this module can connect an SLC 5/02 or higher processor to up to 63 DeviceNet I/O devices on a single network. Typical applications include integrating DeviceNet sensors, actuators, and I/O devices into legacy automation systems for centralized control and reliable field connectivity. As part of the 1747 Remote I/O family, the 1747-SDN enables seamless DeviceNet communication within Rockwell Automation’s SLC-based control architecture.
