Electrical data
The SERCOS coupler BK7500 and BK7510 differ by virtue of their capacity
levels. The following data distinguishes between a standard and an
economy variant (BK7500 and BK7510). Compatability with the other
SERCOS components is guaranteed in any case. Contrary to the standard
bus coupler, the economy variant is limited of the number of I/O´s. Thus,
there is no possibility of connecting inputs and outputs other than digital
ones. The following table lists an overview of all data:

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
terminal, please contact Beckhoff's technical support. .
