Bus Couplers for all usual bus systems The Beckhoff Bus Terminal system unites the advantages of a bus system with the possibilities of the compact series terminal. Bus Terminals can be driven within all the usual bus systems, thus reducing the controller parts count.

When converting to a different bus system it is necessary to bear in mind the need to change the timeout periods if the bus cycle time is longer. The interfaces A Bus Coupler has six different methods of connection. These interfaces are designed as plug connectors and as spring-loaded terminals. BK7150 Version: 1.0.0...
Complex signal processing for analog I /Os, position measurement, … The BK7150 Bus Coupler supports the operation of all Bus Terminals. As far as the user is concerned, handling of the analog inputs/outputs is no different to other series. The information is available in the process image of the controller for processing in the form of a byte-array.

3.1.1 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.

PE power contact The power contact labelled PE can be used as a protective earth. For safety reasons this contact mates first when plugging together, and can ground short-circuit currents of up to 125 A. Version: 1.0.0 BK7150...
3.2.1 Potential groups, insulation testing and PE Potential groups A Beckhoff Bus Terminal block usually has three different potential groups: • The fieldbus interface is electrically isolated (except for individual Low Cost couplers) and forms the first potential group. • Bus Coupler / Bus Terminal Controller logic, K-bus and terminal logic form a second electrically isolated potential group.
Bus Coupler / Bus Terminal Controller can also be used for supplying the power contacts. PE power contacts The power contact labelled PE can be used as a protective earth. For safety reasons this contact mates first when plugging together, and can ground short-circuit currents of up to 125 A. Version: 1.0.0 BK7150...
10 mm out from the connected group of other terminals. In that case, the PE conductors do not have to be disconnected. The power contact with the label PE must not be used for other potentials. 3.2.2 CC-Link Fig. 7: CC-Link-Anschluss CC-Link wiring Use a resistor (R = 110 Ω) to terminate open ends.

• from an isolated source protected by a fuse of max. 4A (according to UL248) or DANGER • from a voltage supply complying with NEC class 2. An NEC class 2 voltage source must not be connected in series or parallel with another NEC class 2 voltage source! Version: 1.0.0 BK7150...
The current load from the power contact must not exceed 10 A for long periods. The current carrying capacity between two spring-loaded terminals is identical to that of the connecting wires. BK7150 Version: 1.0.0...

Bus Terminal the blade contacts on the left hand side of the Bus Terminal are connected to the spring contacts. The tongue & groove design of the top and bottom of the Bus Coupler / Bus Terminal Controller and Bus Terminals enables secure fitting of the power contacts. Version: 1.0.0 BK7150...
80 DI/80 DO and/or 12 channel in/out (24 Byte in/out) 112 DI/112 DO and/or 16 channel in/out (32 Byte in/out) On start up, the BK7150 reads the terminals and configures the CC-link interface. The I/O error LED the coupler shows which mapping is active.
