西门子分源型(PNP)或漏型(NPN)。
1，漏型逻辑：当信号输入端子流出电流时，信号变为ON，为漏型逻辑。 电流是从端子流进去的，具NPN晶体管输出特性。
2，源型逻辑：当信号输入端子流入电流时，信号变为ON，为源型逻辑。 电流是从端子流出来的，具PNP晶体管输出特性。
以正电源为例：
当信号端子发出“ON”信号时，如果此时其电压为低电平（0V），则为漏型逻辑；
当信号端子发出“ON”信号时，如果此时其电压为高电平（PLC、变频器等一般为24V），则为源型逻辑。
源型输入就是高电平有效，意思是电流从输入点流入，漏型输入是低电平有效，意思是电流从输入点流出。
三菱现在的FX3U是可以选择源型和漏型的。
