Please use U-shaped contact tag to set NPN mode or PNP mode and the internal or external power supply.
The default setting is NPN internal mode.
Figure 3-11 U-shaped contact tag
If the signal is from NPN transistor, please set the U-shaped contact tag between +24V and PW as below
according to the used power supply.
