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.
