Review on πŸ’‘ Enhanced Power Relay Module for Advanced Control Voltage Management by Johnnie Bowlan

Revainrating 4 out of 5

Was working to fix an issue with the Nest thermostat.

Bought to control the heater relay on my stove. I have a nest thermostat and the heater relay pulls through an amplifier which caused the nest to fail because it's only rated for about 250mA. I first bought a standard relay box that could be controlled with an outlet and loaded the relay instead. The relay box I bought was supposed to work on 24V AC, but after trying three different relays they all had a rattling problem, probably due to the AC control voltage and because the relays were cheap. I bought this relay because it specifically states that the control signal can be 24VAC or DC. Plugged it in where I had my old relay and it works like a charm. EDIT: The device failed in less than two weeks. I'm waiting for a replacement from Revain. I'm deducting a star and will keep updating if a second device fails in a similar way. EDIT 2: The 2nd works great.

Pros
  • This is a simple and practical passive relay module, very convenient to use. It can support both normally open and normally closed modes. Two screw mounting holes are convenient for mounting on a wall or wooden board. Of course, you can also choose not to block the screw.
Cons
  • Not trendy
