Product Introduction
The Allen Bradley 1747-ASB Remote I/O Adapter Module is a communication interface module designed to connect remote I/O racks to an Allen-Bradley PLC system via the Remote I/O (RIO) network. It functions as the communication gateway between the scanner module and distributed I/O chassis, enabling reliable data exchange between the controller and field-level input/output devices.
This adapter allows remote racks to operate as an extension of the main control system, significantly reducing wiring complexity and improving system scalability. The 1747-ASB is widely used in SLC-500 based architectures where deterministic and cyclic I/O communication is required for industrial automation processes.
Engineered for continuous industrial operation, the 1747-ASB offers stable communication performance, robust electrical design, and seamless integration into Allen-Bradley Remote I/O networks.
