What kind of load do you need? The Krida you linked to one has 2A per
channel.

If you need more, this one has 4A per channel, but you need two of it to
reach 7 channels. More expensive, but no high voltage work required.

I guess it does the job.
It will only switch things on and off, not dim them. For that you
want something with triacs or scrs like this:

and there are "DMX interfaces" that present themselves as
MIDI devices
(either they have MIDIin and DMXout; or they show up as MIDI
devices
when connected via USB)
