4.3.6 Input /Output signal connection figure
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.
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.
Installation Guidelines
