that could be what going on with regards to the mechanical realy but what about the solid state relay failing? They're going to get me all the pertinate data so I can look deeper in to it.
it's typically just signal to "start cycle" of the accesory. I actually thought the same thing but it even happens with solid state relays. I'll find out the max current draw and let you know.
I have a customer that is having an issue with a relay staying closed. They are using this relay to allow their customer to get a "go" signal to another piece of equipment. Sometimes the secondary signal is DC and sometimes it's AC. It doesn't always happen. They've tried solid state relays...
