1794-IE4XOE2 is a product code that corresponds to an input/output module in the Allen-Bradley Flex I/O series. Allen-Bradley, a brand owned by Rockwell Automation, offers a wide range of industrial automation and control products.

Analog Inputs: The module provides a certain number of analog input channels (indicated by the product code) for measuring continuous voltage or current signals from sensors, transducers, or other analog devices. It may support different input signal types and provide high-resolution measurements.

Digital Outputs: The module also offers a certain number of digital output channels for controlling devices such as solenoid valves, motors, relays, or other discrete devices. Digital outputs provide on/off control signals.

Communication: The 1794-IE4XOE2 module interfaces with the system through a communication link, typically using an I/O bus such as DeviceNet, EtherNet/IP, ControlNet, or Profibus.

Flex I/O System: The 1794-IE4XOE2 is part of the Flex I/O product line, which is known for its modular and flexible design. The modules can be easily added, removed, or reconfigured to meet specific application requirements.

Configuration and Programming: To use the module effectively, programming and configuration software, such as the Rockwell Automation Studio 5000 environment, can be used to set up the module, define inputs and outputs, and establish communication with the overall control system.
