This product is a complete waste of money in the Industrial and Scientific category. Based on our own experience, this product failed to work as advertised and actually caused more problems than it solved. The only positive thing we can say about it is that it is easy to install. However, the cons massively outweigh the pros, with the product not delivering on its promise of optocoupler isolation support. Save your time and find a different product that actually delivers what it says it will.
