Here are some key features of the 1746-NO8I module:

Isolation: Each output is electrically isolated from the other outputs, which helps prevent common-mode noise and interference.

Low-side switching: The module uses low-side switching, meaning it can sink current from the load devices to the common power supply. It is important to ensure that the load devices are properly wired for this type of control.

Current rating: The 1746-NO8I module is capable of sinking up to 0.5 Amps of current per channel.

LED indicators: Each output channel has an LED indicator that provides status indication for easy troubleshooting and diagnostics.

Configuration: The module can be configured and programmed using RSLogix 500 software or other compatible programming tools. The programming allows you to define the behavior of each output channel and set various parameters.

The 1746-NO8I module is commonly used in industrial automation and control applications where discrete digital outputs are required.
