## Customer Reviews

### ⭐⭐⭐⭐⭐ Does the job perfectly
*by A***X on 21 February 2025*

Good quality, you can choose high and low trigger voltage. Terminals could be a bit bigger. Well-packed, individually in antistatic bags.

### ⭐⭐⭐⭐⭐ Good value
*by P***. on 25 December 2022*

These relays work well with both high and low level inputs. One thing that lets them down is the quality of the screw terminal blocks - I have seen better.

### ⭐⭐⭐⭐ Works fine, but not isolated - useless optocoupler, apart from using the manufacturer's inventory.
*by C***D on 15 March 2025*

Works as expected, though, like for a lot of other modules coming from China, claiming optocoupler isolation is pure nonsense in the way it is designed. To have an isolated module, there shall be two completely separated connections points, at the LED side of the optocoupler, with no common ground to the supply. Other than this, the device can be designed very well without an optocoupler, being as "isolated" without the optocoupler, as it is with the optocoupler. This module is, of course, non isolated, but it does the job I need it for.
