Review: CNC router noise isolation - Was getting feed back on my arduino uno from the end stop sensors and alarming up as soon as I started the router. Put this module in and working great. Would recommend for noise isolation and false triggers. Have 24 volt inductive sensors switching to 5 volts onto the arduino inputs through the module.
Review: Didn't work properly - This item reduced TTL voltage signal to 5v OK... but when switch to off 3v still showing. Which makes it useless.

## Features

- WIDELY USED: It can be used for signal isolation, PLC signal level converting, PNP/NPN signal to NPN signal and signal level voltage converter.
- EASIER TO RECOGNISE: Each channel has been equipped with indicator which is easier to recognise the working status.
