The 1794-IE8xOE4 module provides 8 channels of digital I/O. These channels can be configured individually as either inputs or outputs, allowing for flexible configuration based on the application requirements. Each channel can handle a voltage range of 20.4 to 26.4 volts DC and provides isolation between field-side and system-side circuits.

In terms of input functionality, each channel can accept a 24V DC signal as a logic high, and any voltage below 5V DC is considered a logic low. As for output functionality, each channel can provide a 24V DC signal when driven high and is capable of sinking up to 2A of current when driven low.

The 1794-IE8xOE4 module is typically used in industrial automation applications where there is a need for monitoring and controlling digital signals. It can be used with various voltage levels and is commonly utilized in the oil and gas, manufacturing, and process industries.
