Three additional module racks in Aluminium design are now available for S7-400 :

The range of module racks for S7-400 has been supplemented by three additional Aluminium versions. The use of Aluminium for the racks improves their stability against adverse ambient conditions. Their weight is approx. 25% less and the racks are more warp resistant.
