Input and Output Parameters: NPN / PNP Input NPN Output 3.3V to 3.3V 3.3V to 5V 3.3V to 12V 3.3V to 24V 5V to 3.3V 5V to 5V 5V to 12V 5V to 24V 12V to 3.3V 12V to 5V 12V to 12V 12V to 24V 24V to 3.3V 24V to 5V 24V to 12V 24V to 24V Package Included: 1pcs NOYITO 4-Channel Optocoupler Photoelectric Isolator Module Level Voltage Converter Module

Review: Works perfectly. - Needed to swap a PNP to an NPN for a CNC project. Worked right out of the box and was simple to wire. Created a little 3D printed case for it to keep it clean and make it easy to mount.
Review: Perfect for Arduino and Geckodrive G540 - Works great to switch higher voltage logic signals with an Arduino. I'm using this on a CNC plasma cutter with an Arduino based torch height controller and Geckodrive G540. The G540 is powered by 24VDC and it's inputs are 12V logic active low. This module (5V->24V) allows the Arduino outputs to control the G540 inputs, and also provides an additional layer of isolation between the high voltage plasma source and the PC running Mach3

### ⭐⭐⭐⭐⭐ Works perfectly.
*by A***T on January 26, 2025*

### ⭐⭐⭐⭐⭐ Perfect for Arduino and Geckodrive G540

Works great to switch higher voltage logic signals with an Arduino. I'm using this on a CNC plasma cutter with an Arduino based torch height controller and Geckodrive G540.

### ⭐⭐⭐⭐⭐ Worked perfect for my DIY CNC Machine
*by M***R on October 14, 2020*

Before adding this to my DIY Arduino based CNC machine I was having jobs constantly interrupted by noise on my limit switch inputs. Twisted shielded cables and capacitors helped, but the problem didn't go away until I added this between all my limit switches and the input pins on my CNC hardware. 4 channels is perfect for X, Y, Z and even the probe.
