I was curious about what to do if you have to convert a smaller panel to DIN rail. I know there is the PD-PNL-8-SUB that has the sub panel and cover, but what about the smaller 5 RPM panel? Is there a solution for that other than putting in a whole new panel? I'm sure I could just screw on some din rails and make it happen that way but I'm guessing the UL rating would be gone if I did. Or just use the new link translator and keep the RPMs.
