Introduction
Are you still distressed that industrial sensors can’t be used on the Arduino? You may need to get a converter just like this!
This 12V to 3.3V level converter module with 4-channel Optocoupler isolation features common anode / common cathode / differential signal inputs. The level shifter translates signal level from 12V to 3.3V and offers PNP output (NPN to PNP available). It can be used for signal isolation, PLC signal level conversion, NPN to PNP signal conversion, polarity conversion, signal level voltage conversion and so on.
Wiring Diagram of Common Anode Signal Input
Note: DC power supply positive is equal to signal output voltage. For example: 12V to 3.3V module, then VCC=3.3V.
