Re: sherline motor/speed control wiring IT WORKS!

hey Alan
I tired several different relays but there is not enough current to
trigger it. I did not try a SSR however. Have you connected a relay
to yours and had it click over? If so which relay did you use. If so
then connecting that to I1 and I2 on the sherline board is all that
is needed to start and stop the motor. I asked my brother (he is the
electronic guru) and he is coming up with a circuit using and opto-
coupler. Will let you guys know if it works.
thanks
