Looking to interface high voltage or noisy signals with a microcontroller, Raspberry Pi, or Arduino? Look no further!
This 8 channel input optoisolator board accepts nominal voltages of 5-24V (max of 40V) on the input side, while generating clean and regulated 3.3-5V signals on the output side. Feeding an input a LOW/grounded state will produce a LOW/grounded state on the output and vice versa.
The latest revision (1.1b, shown below) now has screw holes for easy mounting.
With large screw terminals, clearly visible LEDs indicating state, and optional 2.54mm headers, this board is a breeze to work with.
While retrofitting/updating CNC machines in our shop with Arduinos and Raspberry Pis, we realized very few options existed for cleanly connecting 24V signals to our favorite low cost development boards. Rather than hacking together several smaller boards or modifying less than ideal existing solutions, we developed this robust and simple optoisolator board ourselves.
Note that this board is able to adapt to the specific voltage ranges required of your use case. The HVIN pin is used to select the voltage of input signals, while the LVIN pin is used to select the voltage of the output signals.
