The space-optimized industrial PC for automation is installed where space is at a premium, for example, in cabinets. Three sizes are available. With maintenance-free, no-fan cooling, this device with minimal dimensions extends the series of SIMATIC industrial PCs. On the front, dynamic cooling ribs are oriented toward the products identifying marking. One important objective of the design was to find an original, novel characteristic for the ribs. The LEDs highlight this variant. The design is intended to achieve an apparent reduction of the real dimensions. Optimized production costs are combined with clear usability.
