That does not work.

I don't know how others use this with 3-3.3V DC. It doesn't work for me and I'm very frustrated. I hear the relay click but it does NOT close NO and COM so I can use that.

Pros
  • Controls and Indicators
Cons
  • No Instructions

High quality and good performance with 3V logic

They serve their intended purpose well. I had to find a controller that said it would work with 3V microcontrollers (like those from Adafruit). I am happy to report that this job is perfect for my needs (automatic greenhouse).

Pros
  • Industrial & Scientific
Cons
  • Very expensive

Compatible with Raspberry PI and 12V DC

I've had this running for months with no problems. I am using it to remotely control the opening and closing of a chicken coop door via a Raspberry PI. It stays active as long as there is a signal coming from the gpio pin on the Pi to the "in" connector. VCC In and GND are the side of the Pi (which gives the commands). NC, COMM and NO are for the regulated circuit. "NC normally closed" "NO normally open" and communication is where the power supply is switched. To have power only when "IN" is…

Pros
  • Industrial Electrics
Cons
  • High Price
