Allen-Bradley 1794-ADN | DeviceNet Adapter for Flex I/O Systems

Product Overview

The 1794-ADN DeviceNet Adapter by Allen-Bradley connects Flex I/O racks to central DeviceNet scanners, enabling reliable I/O data exchange. It supports installation of up to eight Flex I/O modules in any combination, improving system scalability and flexibility.

Designed for both DIN rail and panel mounting, the 1794-ADN provides convenient installation and stable operation. Operators can monitor module performance using red/green status LEDs for Mod/Net and I/O conditions. Module addressing is simple with embedded thumbwheel switches, allowing settings from 00 to 63, while baud rate is automatically detected during power-up.

The adapter operates at 24VDC nominal, with a power range of 19.2–31.2VDC and provides FlexBus output current of 640 mA at 5VDC. It supports data transmission rates of 125KB, 250KB, and 500KB, making it suitable for a variety of industrial automation applications.
