If you need the same logo sized for different sizes of screens, you can choose "export for screens" from the file menu. But, I personally prefer to manually do it in Illustrator by scaling the logo up or down.
You can create multiple artboards and size each to the specific pixel dimensions. Copy the logo into the new artboards and scale it to fit. Then, choose "export" from the file menu, click on the check box to choose "all artboards," and pick the file format.
