Hi,
I use MB026's from Peter Homan, Homan Designs, Austrailia. Near enough to local for me.
They've been great. They don't have either a digital to analogue output nor relays or 24V
outputs. I'm into electronics so any of those I prefer to design and build my own.
What they do have which I'd have to recommend, in fact would say they are mandatory is LEDs
on all inputs and outputs.
I might be into electronics but personal experience tells me the risk of me blowing something up
when trying to probe a board or connector with a multimeter is high. Don't do it! One slip and it can,
at worse case, be all over for the board your working on. LEDs on the outputs obviates the need
for it and you can see all of them at a glance, just the 'dogs dangly bits'.
I'll post a pic but may not be able to do so tonight.
