Allen-Bradley 1747-ASB ASCII Interface Module is a single-slot Remote I/O Adapter for the SLC 500 family that maps the images of remote I/O modules in a backplane to the SLC processor, enabling data exchange across the Remote I/O (RIO) link. Designed to work with SLC 500 controllers and compatible with Allen-Bradley scanners, the 1747-ASB supports multiple RIO data rates—57.6 kbps, 115 kbps, and 230 kbps—providing flexible communication options for different network configurations. The 1747-ASB occupies a single slot in the remote I/O chassis and provides the ASCII interface that connects the processor to the remote I/O modules over the RIO network.
