官方文档中不同DO板卡输出类型不同,有Sink(NPN)和Source(PNP)两种。 图1 DO板卡的两种输出模式 问题: 按照下图接好板卡和继电器线路,在labview程序中控制IDO1为数字量“1”,则右侧继电器管脚5 接9or悬空? 图2 1734外接继电器原理图 分析: 下面是1734板卡内部原理图,虚线左侧为内部电路,右侧为板卡外部电路。 由...
But, in each of these, there are common components and concepts. Sink & Source connections are these types of connections presented in most of PLC’s vendors. Today we are going to learn how to make aSink or Source connectionand also, we will clarify the difference between both the connect...
since both modules allow thecompletion of a circuitfrom + to -. It is rare to encounter output devices that are restricted to either PNP or NPN, but it can be seen on some light towers and other devices, so it’s still important to understand the relationship. ...

一组IN。对于sourceandsink只是叫法不同而已。欢迎10115292哪位朋友对选电机 有经验的请教了。“请教如何选择电机容量?机械功率怎么确定呢?比如要给一般物料 (物料按1吨计,不考虑提升台自重)提升机配两台电机(一变频器驱动双电机双链提 升),如何选择电机额定功率(普通三相异步电机)呢” 2个PN结的方向不一致。 PN...
Manual saysSink/Source (IEC Type 1 Sink, except I0.3 to I0.5) so it should be possible to use both types by connecting negative to common for PNP or positive for NPN. The drawback is that all inputs connectet to that common have to be of the same type. Suggestion To thank Quote ...
PNP is a Bipolar Junction Transistor or BJT in which holes are the major current carriers, while electrons are minor. The arrangement of the PNP transistor is in such a way that the P-type dopedsemiconductoris separated by a thin layer of N-type doped semiconductor material. ...
