Using 3 channel controller to run relays.

Thanks for the reply. It's a solid state relay same as the one below in the link. Only going to be using 2 of the channels. It looks to have resisters and possibly diodes on the board so hopefully it will be ok.

Will give it a try and see what happens. Lol.
