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 terminal controller. 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 terminal controller 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 terminal, please contact Beckhoff’s technical support.
