Allen‑Bradley 1747-ASB SLC 500 Remote I/O Adapter Module

The Allen‑Bradley 1747-ASB is a remote I/O adapter module designed for the SLC 500 PLC system. It establishes remote I/O communication links between the SLC chassis and main processor, enabling distributed layout of I/O racks to place field signal modules closer to production equipment and shorten wiring distance.

This module supports standard Allen‑Bradley remote I/O communication protocol and provides comprehensive network status diagnosis. It adopts single-slot chassis installation, widely stocked as spare parts for maintenance and reconstruction of old SLC 500 distributed automation control systems.
