Bus Coupler power supply总线耦合器电源
The Bus Couplers require a 24 V DC supply for their operation. The connection is made by means of the upper spring-loaded terminals labelled 24 V and 0 V. The supply voltage feeds the Bus Coupler electronics and, over the K-Bus/E-Bus, the Bus Terminals. The power supply for the Bus Coupler electronics and that of the K-Bus/E-Bus are electrically separated from the potential of the field level. 总线耦合器需要一个24V DC电源的操作。连接是由上弹簧型端子的方式作出标记24 V和0 V的电源电压供给总线耦合器电子和，在K-总线/ E总线，总线端子模块。 K总线/ E总线的电源为总线耦合器的电子和电从现场级的潜在分离。
Input for Power Contacts输入电源触点
The bottom six connections with spring-loaded terminals can be used to feed the supply for the peripherals. The spring-loaded terminals are joined in pairs to a power contact. The feed for the power contacts has no connection to the voltage supply for the Bus Coupler. The design of the feed permits voltages of up to 24 V. The assignment in pairs and the electrical connection between feed terminal contacts allows the connection wires to be looped through to various terminal points. The current drawn from the power contacts 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.
用弹簧型端子的底部6连接可以用于饲料对于周边的供应。弹簧式接线端子加入对到电源的接触。进料为电触头具有到电压源的总线耦合的连接。进料的设计允许多达24 V电压在对所述分配和进料端触头之间的电连接允许连接线通过各种终端点被环。从电力接触吸收的电流不能超过10甲长时间。两个弹簧加载的终端之间的载流容量是相同的，在连接电线。
Power contacts电源触点
On the right hand face of the Bus Coupler there are three spring contacts for the power contact connections. The spring contacts are hidden in slots so that they can not be accidentally touched. By attaching a Bus Terminal the blade contacts on the left hand side of the Bus Terminal are connected to the spring contacts. The tongue and groove guides on the top and bottom of the Bus Coupler and of the Bus Terminals guarantees that the power contacts mate securely.
在右边的总线耦合器的存在对于电源触点连接三接触。弹簧触头隐藏在时隙使得它们不能被意外触摸。通过将一个总站的左侧的刀片触点连接到弹簧触点。在总线端子的总线耦合器的顶部和底部的榫槽导轨保证了电源触点配合牢固。
Configuration Interface (not for BK1250)配置界面（不适用于BK1250）
The standard Bus Couplers have an RS232 interface at the bottom of the front face. The miniature connector can be joined to a PC with the aid of a connecting cable and the KS2000 configuration software. The interface permits the Bus Terminals to be configured, for example adjusting the
amplification factors of the analog channels. The interface can also be used to change the assignments of the Bus Terminal data to the process image in the Bus Coupler. The functionality of the configuration interface can also be reached via the fieldbus using string communication facility.
标准总线耦合器具有在正面底部的RS232接口。微型连接器可以连接到PC的连接电缆的帮助和KS2000组态软件。该接口允许将配置的总线端子模块，例如调节模拟通道的放大系数。该接口还可以用来改变在总线耦合器的过程映像总线端子模块数据的分配。配置接口的功能，也可以通过使用串通信设施现场总线到达。
Electrical isolation电气隔离
The Bus Couplers operate by means of three independent potential groups. The supply voltage feeds the K-Bus/E-Bus electronics in the Bus Coupler and the K-Bus/E-Bus itself, which are electrically isolated. The supply voltage is also used to generate the operating voltage for the fieldbus.
该总线耦合器通过三个独立的潜在群体的手段。电源电压供给K总线/ E总线电子在总线耦合器以及K总线/ E总线本身，这是电隔离。电源电压还用于产生工作电压为现场总线
Remark: All the Bus Terminals are electrically isolated from the K-Bus/E-Bus. The K-Bus/E-Bus is thus electrically isolated from everything else.
