Let’s look at the components needed to build a Z-Wave controlled dual high current DC relay module.
I want to be able to control 2 DC loads remotely. I use a Z-Wave home automation controller, so that will be my interface. There are DC relay modules available, but most are of a low current design. My prototype used a Z-Wave outdoor appliance module and while it worked fine, it was relatively expensive and bulky.
So my plan is to use this dual relay module from Monoprice:
and put that in an electrical box with two switches and two receptacles and make a single box that I can plug in two 12W wall warts to control 2 12V, 30A relays.
In the next video, we’ll take a look at the finished module and then try to get it talking to my home automation controller and see if it works:
As always, thanks for watching!
