The module SK CU4-MBR
generates an output voltage on
Terminals MB+/MB- for control of
an electromechanical brake. This
depends on the supply voltage and
the connection of the supply cable
to the one-way (L1
E
) or bridge
rectification (L1
B
) of the module.
The assignment of the correct
brake coil voltage must be taken
into account in the selection.
