Allen Bradley 1794-ASB Flex Remote I/O Adapter Module

Product Introduction

The Allen-Bradley 1794-ASB FLEX Remote I/O Adapter Module is a communication interface designed to connect FLEX I/O systems to a Universal Remote I/O network. It enables efficient data exchange between distributed I/O modules and central controllers, making it a reliable solution for extending control systems in industrial environments.

This adapter allows up to 8 FLEX I/O modules to be connected on a single node, providing a compact and scalable distributed I/O architecture. With support for multiple communication rates, it offers flexibility in balancing performance and network requirements across different applications.

Powered by a 24V DC supply, the 1794-ASB is engineered for stable operation in industrial settings. Its compact design and modular integration make it suitable for both new installations and upgrades of existing Remote I/O systems, especially in legacy automation environments.
