1794-ADN Functional Description

The Allen-Bradley 1794-ADN FLEX I/O DeviceNet Adapter Modules is a 24 VDC DeviceNet adapter module designed for industrial automation systems. This versatile module supports communication rates of 125 Kbps, 250 Kbps, and 500 Kbps while capable of managing up to eight Flex I/O modules in any configuration. The compact 24 VDC Adapter ROCKWELL 1794-ADN features an open-type enclosure that accommodates both DIN rail and panel mounting, measuring 3.7 x 3.6 x 3.4 inches for space-efficient installations.

Electrical specifications for the ALLEN BRADLEY 1794-ADN Flex I/O communication module include a nominal input voltage of 24 VDC with an operating range from 19.2 to 31.2 VDC. The module requires a power supply current load of 400 mA and provides a FlexBus output current of 640 mA at 5 VDC. 

AWith built-in status indicators for monitoring I/O and network status, the DeviceNet Adaptor 1794-ADN AB offers reliable performance across an operating temperature range of -4 to 158°F and features robust vibration and shock ratings for demanding industrial environments.

Configuration of the 1794-ADN DeviceNet Adaptor Allen Bradley is streamlined through integrated thumbwheel switches allowing node address settings from 00 to 63, while baud rate is automatically detected during power-up. The module includes one DeviceNet port compatible with standard 5-pin or 10-pin linear plugs and recommends using Belden YR-29832 or equivalent cabling for optimal network performance. These features make it an essential component for creating flexible and scalable control systems in modern manufacturing facilities, providing both reliability and ease of integration.
