## Description

Quickly converts 3.3V logic signals to 12V for safe control of industrial loads, ideal with Arduino and other development boards. It has 4 channels, optoisolation for electrical separation, PNP input with common cathode and 12V output proportional to the logic level. It is powered by 12V on VCC and GND, screw terminal connections.
Logic level converter module, from 3.3VDC to 12VDC, with optoisolator, compatible with Arduino and other development boards, with common cathode, PNP.
It has 4 channels and is used when you want to convert a 3.3V to 12VDC logic signal.
Power supply required for the output voltage, in the case of this module, of 12VDC connected to the VCC and GND pins (they are easily recognized because they have the Blue connector.
For each separate input, the Plus and Minus of the 3.3V signal will be connected, and on the output there will be only the output pin of the signal modified to 12V.
A High Level signal of 3.3V on the input corresponds to a signal of 12V on the output. A Low Level signal of 0V on the input corresponds to a signal of 0V on the output.
