Description
Product Overview
The Allen‑Bradley 1747‑ASB is a single‑slot remote I/O slave adapter module for SLC 500 and PLC‑‑5 automation systemsRockwell A…. Installed in slot 0 of a 1746 remote chassis, it acts as gateway between RIO scanner hardware and local 1746‑series I/O modules inside the remote chassis and expansion racksRockwell A…. It transfers input signals from field I/O back to the main scanner and writes output data received over the RIO link onto chassis backplane without extra user programming workRockwell A…. Equipped with 3‑digit 7‑segment status display plus COM / FAULT LED indicators for fast on‑site troubleshooting, this module is widely used for legacy Rockwell system maintenance and spare‑part replacement projects.
Series
SLC 500 control platform, including SLC controllers, 1746 I/O racks and multiple communication modules for classic PLC distributed‑I/O automation.
