This is a continuation from my post on Mach forum. I debated about starting here Bob but I saw the other post on the Mach forum so I jumped in their. You were correct it was a noise problem. The funny thing was the only thing the K1 relay was driving when I was testing was an extension cord that has a neon light molded in the female end so you can tell it has power. As soon as I removed the extension cord it I could hear the relay click on and stay on. I should have suspected noise because a few times it did work properly when testing. That was most likely because I turned it on close to the zero crossing of the AC.
Under plugin control I selected the SS and there are adjustment for noise filtering. Everything was set to 0. I changed the limits filtering to 10 which I thick that an input has to be active for 14.3 micro seconds to valid now. It all is working now.
Thanks for your help. PMDX has the best tech support and products!!
