P0926GH端子模块,P0926GH用户手册
6安装接线盒PFXC 141PFXC 141通常用于连接Pressductor?称重传感器。电缆固定在称重传感器和连接至控制单元的电缆应连接至接线盒。接线盒PFXC 141应安装在称重传感器附近，并位于易于维修的受保护位置。根据订单特定图纸安装接线盒。接线盒的尺寸如图2-10所示。未使用的孔必须堵住。电路图见附录A.6.4接线盒PFXC 141，共有六个模拟输出。每个输出可以设置为电压或电流。
P0926GH端子模块每个模拟数字/模拟转换器的输出为电压。这被分为两个输出，其中一个转换为电流输出，另一个保持为电压。如图2-12所示例如，其中X4:1是电压输出，X4:2是电流输出。电压输出的允许负载电流最大为5 mA。电流输出的允许负载电阻最大为550欧姆。图2-12显示了连接电压输出的AO1和连接数字输出（DO1-DO4）的电流输出的AO2四个数字输出DO1-DO4作为一组绝缘。见图2-14。数字输出为电流驱动，可以从外部24 V DC或用于PFEA113的24 V直流电源。状态“1”下的电流最大为0.1 A/输出。连接数字输入（DI）数字输入是具有以下数据的差分输入：无源：-36 V至+5 V激活：>16 V（最大+36 V）6 Installing Junction Box PFXC 141
PFXC 141 are normally used for connection of Pressductor? load cells. The cables fixed to the
load cells and the cable to the control unit are to be connected to the junction box.
The junction box PFXC 141 shall be mounted adjacent to the load cells and located in a
protected position easily accessible for service.
The junction box is mounted according to an order-specific drawing.
The dimensions of the junction box are shown in Figure 2-10.
Holes not used must be plugged.
For circuit diagram see Appendix A.6.4 Junction Box PFXC 141There are six analog outputs. Each output can be set either for voltage or current. Each analog
output from the digital/analog converter is a voltage. This is split into two outputs, one of which
is converted into a current output and the other kept as voltage. This is illustrated in Figure 2-12
where for example X4:1 is the voltage output and X4:2 is the current output.
The allowed load current of the voltage output is max. 5 mA.
The allowed load resistance of the current output is max. 550 ohms.
Figure 2-12 shows AO1 connected for voltage output and AO2 for current outputConnecting Digital Outputs (DO1-DO4)
The four digital outputs, DO1-DO4, are insulated as a group. See Figure 2-14.
The digital outputs are current driving and can be supplied from an external 24 V DC or from
the 24 V DC supply used for PFEA113.
The current at state “1” is maximum 0.1 A per output.Connecting the Digital Input (DI)
The digital input is a differential input with the following data:
Passive: -36 V to +5 V
Active: >16 V (maximum +36 V)
