Allen Bradley 1794-ACN Flex I/O ControlNet Adapter Module

Product Introduction

The Allen-Bradley 1794-ACN Flex I/O ControlNet Adapter Module is a high-performance communication interface that connects Flex I/O modules to a ControlNet network. It serves as a bridge between the I/O scanner port and distributed I/O devices, allowing centralized controllers to monitor and control remote I/O efficiently.

This adapter integrates a built-in power supply, converting 24 VDC nominal supply to 5 VDC for the Flex I/O backplane, supporting a maximum output current of 640 mA. It supports up to 8 Flex I/O modules per adapter, facilitating scalable system design. With a ControlNet communication rate of 5 Mbps and an isolation voltage of 850 VDC, it ensures robust signal integrity and network reliability even in industrial environments.

Compact, lightweight, and easy to install, the 1794-ACN is ideal for distributed automation applications requiring fast and secure communication between controllers and remote I/O devices.
