I appreciate that the model 6ES7 321-1BL00-0AA0 follows the same pin layout we already use in panels.

What stands out about the 1769-IT6 is its straightforward compatibility with common I/O racks.

A nice touch is that the Allen Bradley 1746-NO4I SLC 500 labels line the panel.

With the 17R, the mounting holes line up very well on standard rack systems.

A nice touch with the Allen-Bradley 1746-OA16 is how easy documentation is to follow.
