This assembly is in great used physical condition with normal installation and handling wear. There is a slight chip in the blue plastic cover and the slot 8 label panel guard is missing (clearly photographed). The internal CPU battery features a label reading "10/20/2021"—due to its age, the remaining charge has not been verified, so please budget for a standard battery replacement if retaining program memory without line power matters to your system.While this specific rack was not separately bench-tested, it was removed from the exact same control panels supplying my listed Siemens Servo Motors and Spindle Motors, which have all successfully passed our rigorous bench testing.(Please Note: Front connectors, bus connectors, terminal blocks, CP configuration software, or external cabling are not included unless they are clearly visible in the photos.)
