P0926GH端子模塊,P0926GH用戶手冊
6安裝接線盒PFXC 141PFXC 141通常用于連接Pressductor?稱重傳感器。電纜固定在稱重傳感器和連接至控制單元的電纜應(yīng)連接至接線盒。接線盒PFXC 141應(yīng)安裝在稱重傳感器附近，并位于易于維修的受保護位置。根據(jù)訂單特定圖紙安裝接線盒。接線盒的尺寸如圖2-10所示。未使用的孔必須堵住。電路圖見附錄A.6.4接線盒PFXC 141，共有六個模擬輸出。每個輸出可以設(shè)置為電壓或電流。
P0926GH端子模塊每個模擬數(shù)字/模擬轉(zhuǎn)換器的輸出為電壓。這被分為兩個輸出，其中一個轉(zhuǎn)換為電流輸出，另一個保持為電壓。如圖2-12所示例如，其中X4:1是電壓輸出，X4:2是電流輸出。電壓輸出的允許負載電流最大為5 mA。電流輸出的允許負載電阻最大為550歐姆。圖2-12顯示了連接電壓輸出的AO1和連接數(shù)字輸出（DO1-DO4）的電流輸出的AO2四個數(shù)字輸出DO1-DO4作為一組絕緣。見圖2-14。數(shù)字輸出為電流驅(qū)動，可以從外部24 V DC或用于PFEA113的24 V直流電源。狀態(tài)“1”下的電流最大為0.1 A/輸出。連接數(shù)字輸入（DI）數(shù)字輸入是具有以下數(shù)據(jù)的差分輸入：無源：-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)
