Which Electromechanical relay
-
Hi
I want to use an Electromechanical relay to switch the current on and off going to the 24v power supply using the PS_ON connecter on the Duet Ethernet.
The problem is that I'm a Machinist and not an Electrician and I don't know which relay to use!
There are so many different ones out there.
Maybe someone could recommend a good relay to use.Thanks

So you'll be supplying 5v power permanently using a USB supply or similar, so you need a relay with a 5v coil on the low side. Search for 5v power relay module.
These type of units often have transistors, diodes and opto couplers to protect your duet board from either high-voltage or flyback voltage from coils de-energising. They need to be powered from your USB power source also.

Thank you Simon!
That helped tremendously! Using the right words in a search changes everything.
When I was searching for " Electromechanical relay " I was only coming up with the relays by themselves,
but when you search for " 5v power relay module " you get a total different results .Thanks again
