The 2-Channel Level Converter translates 12V signals down to 3.3V using optocoupler isolation, making it easy to interface industrial sensors and PLC signals with 3.3V microcontrollers like Arduino. It supports common anode, common cathode, and differential signal inputs with PNP output (NPN to PNP conversion available).

The module includes SMD LED indicators for each channel and comes in a DIN rail-compatible enclosure for clean installation in industrial and prototyping environments.
