Overview

The Allen-Bradley 1794-ASB is a FLEX I/O Remote I/O (RIO) communication adapter module designed to connect FLEX I/O systems to Allen-Bradley PLC controllers through Remote I/O networks. The adapter serves as the communication interface between the controller and distributed FLEX I/O modules, enabling reliable data exchange in industrial automation systems.

The 1794-ASB supports up to eight FLEX I/O modules and provides flexible addressing capabilities for distributed control applications. It is widely used in manufacturing, material handling, water treatment, power generation, and process automation environments where remote I/O architectures are required.
