NOTICE
Overheating if ventilation clearances are too small
Insucient 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.

Characteristics
The DMC20 and DME20 DRIVE‑CLiQ hub modules are used to implement point-to-point
distribution of a DRIVE‑CLiQ line.
• DMC20 is the hub for the control cabinet conguration
• DME20 is the hub for use without a control cabinet (IP67 degree of protection).
The modules are particularly well suited to applications that require DRIVE-CLiQ link nodes to be
removed in groups without interrupting the DRIVE-CLiQ link and therefore the data exchange.
The DMC20/DME20 is also used with a SIMOTION D410‑2 when a second encoder is required.
As an SMx Sensor Module and a motor with DRIVE-CLiQ interface only have one DRIVE-CLiQ
interface, a DMC20/DME20 must be used for a second encoder via DRIVE-CLiQ. If a CUA31/
