12V to 3.3V 2/4-Channel Photoelectric Isolation Level Converter Module

SKU: DFR0911

Are you distressed industrial sensors can't be used on Arduino? Try this 12V to 3.3V level converter with 2/4-channel photoelectric isolation (common anode/cathode/differential inputs). It shifts 12V to 3.3V, offers PNP output (NPN to PNP), and works for signal isolation, PLC conversion, NPN-to-PNP/polarity/voltage changes. NOTE: Module VCC equals signal output voltage (e.g., 3.3V for 12-3.3V module).
