The 1794-OM8 is a digital output module from Rockwell Automation's Allen-Bradley 1794 Flex I/O series. This module is designed to provide digital output signals to control external devices or processes in a programmable logic controller (PLC) system.

Here are some key features of the 1794-OM8 digital output module:

- It supports up to 8 digital output channels.

- The module provides relay outputs, which are commonly used for controlling devices that require higher power or for driving larger loads.

- The 1794-OM8 module offers a robust and reliable output interface, capable of switching high current loads.

- It can be easily configured and integrated into the Flex I/O system using Rockwell Automation's software tools, such as RSLogix 5000 or Studio 5000.

The 1794-OM8 digital output module is commonly used in industrial automation applications where control of digital signals is required. It is often used for controlling solenoids, motors, valves, indicators, and other devices that rely on digital switching.
