Current consumption on the
K-Bus
For operation of the K-bus electronics, the bus terminals require energy
from the K-bus that is supplied by the bus coupler. Refer to the catalog or
the corresponding data sheets of the bus terminals for details of the K-bus
current consumption. In doing so, pay attention to the maximum output
current of the bus coupler that is available for powering the bus terminals.
Using a special power supply terminal (KL9400), power can be fed back
into the K-bus at any chosen point. If you wish to use a power supply ter-
minal, please contact Beckhoff’s technical support. .
