Dimensions
The system of the Beckhoff Bus Terminals is characterized by low physical volume and high modularity. When
planning a project it must be assumed that at least one Bus Coupler and a number of Bus Terminals will be used.
The mechanical dimensions of the Bus Couplers are independent of the fieldbus system.
The total width in practical cases is composed of the width of the Bus Coupler with the KL9010 Bus End Terminal and
the width of the Bus Terminals in use. Depending on function, the Bus Terminals are 12 or 24 mm wide. The front
wiring increases the total height of 68mm by about 5 to 10 mm, depending on the wire thickness.
