*) The module with the lowest tolerance is always decisive for the permitted voltage tolerances (see
manual for relevant module or for relevant pneumatics).
Special technical specifications on the pneumatics used, on
CPX modules, connection blocks and the CPX bus node can
be found in the relevant manuals.
