Two notes on it. There is room in that enclosure to have scooted the chassis over and bought identical racks rather than mixing sizes. And there is no switch visible, which is unusual at that scale, though it works if the single controller runs one port to the remote rack over EtherNet/IP and the other to the plant network. No cooling either, which is defensible with no VFDs in the cabinet but is not what I would normally expect.\nThe worst panel is the one that makes the point. Someone acquired a cabinet holding ten Festo servo drives with a Weidmuller ProTop supply feeding 24 volts at 40 amps, and every motor and feedback cable has been cut off at the drive. Those terminal blocks release with a small screwdriver into the blue notch. It takes seconds. Instead the whole harness was severed, so whoever bought that equipment now has to strip and re-terminate every conductor before anything runs. It is recoverable and it was unnecessary, and it tells you what kind of shop handled the teardown. If you are buying used industrial hardware, look at how it came out of the building.\nA...","thumbnail_url":"https://img.transistorcdn.com/bLSthDC6mLkQ3vEghIEbytYZBvBBofsfsFEpsA-BvSs/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS83ZDg0/MTRlOGJkNzQxN2Ex/M2NlNjg4N2EwMzI1/MmM4NS5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
