PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1747-ASB remote I/O adapter connects distributed 1746 chassis across a universal remote I/O link. This single-slot module installs directly into Slot 0 of a 1746 series remote chassis. It operates as a slave device on the RIO link. The unit supports optional remote expansion chassis configurations for extended physical I/O capacity.
Hardware configuration requires no software programming and relies entirely on onboard DIP switches. Dedicated FAULT and COMM LEDs provide real-time diagnostic visibility into module status. The module draws 375 mA of backplane current at a supply voltage of 5 VDC. Operating temperatures span from 32 to 140 degrees Fahrenheit (0 to 60 degrees Celsius). Storage temperatures range from -40 to 185 degrees Fahrenheit.
