NOTICE
Overheating if ventilation clearances are too small
Insufficient ventilation clearances result in overheating and therefore in more failures and a 
shortened life of the component.
Maintain 50 mm ventilation clearances above and below the component. The ventilation 
openings may not be covered by connecting cables.

7.11 DMC20 DRIVE-CLiQ hub
Features  
The DMC20 and DME20 DRIVE‑CLiQ hub modules are used to implement point-to-point 
distribution of a DRIVE‑CLiQ line. With the DMC20/DME20, an axis grouping can be expanded 
with four DRIVE‑CLiQ sockets for additional subgroups.  
● DMC20 is the hub for the control cabinet configuration
● DME20 is the hub for use without a control cabinet (IP67 degree of protection).
The modules are especially suitable for applications which require DRIVE-CLiQ nodes to be 
removed in groups, without interrupting the DRIVE-CLiQ line and therefore the data exchange.
