Yes Eddy,
I very much thought so me sen. I only bought it for the spindle 0-10v output, as I have got a couple of these boards http://www.embeddedtronics.com/image/opto/opto_new.jpg. I shall be using one to click relays and sense some inputs. I made 'em up myself so I have spare optos and I have the Eagle files, so I know the circuit.

I just wish I had a circuit diagram for the cheap chinese board - Ah well !

Cheers,

Rob

Now back to the Jim Beam therapy for this persistent cold I have had on and off (mainly on) for the last three months :)
