The 1794-OB8EPXT module provides eight digital output channels. Each channel can be independently controlled and provides a sinking output type. It supports a wide range of voltages, including 24V DC and 120/240V AC.

The "EP" in the module's name stands for EtherNet/IP, which means it can be connected to an EtherNet/IP network for communication and control purposes. This module uses EtherNet/IP as its communication protocol, allowing it to integrate into larger automation systems.

The "XT" in the module's name refers to the extended temperature range capability of the module. It means that this module is designed to operate in environments with higher temperature ranges, providing increased reliability and performance.
