I bought a relay module and after working for a few months, it jitters when it sucks in. The output indicator is normal and I can hear the relay ring a few times before it sucks in. Do you have any recommendations for a reliable relay module?
 

Hi,

This doesn't sound like a relay problem. To me it sounds like a control or power supply problem.

But without details about exact relay type, circuit, power supply... all we can do is guess.
