If I supply 12VDC to the RelayISOx16 and don’t have it hooked up to my spider, all the relays come on. Is there a way of changing this default condition? Basically if my spider fails, it’s going to act like I turned on everything, which seems completely backwards. I would think default state would be “off”.
Right now having an issue with turning on solenoids. As soon as I have one hooked up and turn it on, all the relays clack on. If I don’t have the solenoid connected, the solenoids turn on and off as expected pragmatically. Headed to the store to pick up some diodes to hopefully take care of the solenoid issue, but the back of my head is worried about what happens if my control system goes black, suddenly every solenoid would turn on and do something entirely nasty.
