The interfaces
A Bus Coupler has six different methods of connection. These interfaces
are designed as plug connectors and as spring-loaded terminals.

BK5200, BK5210:
24 V DC to the topmost
terminals “24 V” and “0 V” The Bus Couplers require a 24 V DC supply for their operation. In the case
of the BK52x0 Bus Couplers the connection is made by means of the
upper spring-loaded terminals labelled “24 V” and “0 V”. This supply
voltage feeds not only the Bus Coupler electronics via the K-Bus, but also
the Bus Terminals. In the BK52x0 Bus Couplers the voltage supply for the
bus coupler electronics and that of the K-bus are electrically isolated from
the field level potentials.
