I am having an issue with a Automation Direct 110V AC Input Card(D2-16NA). This is connected to a Automation Direct D205 CPU. I am experiencing an Input Node failure. I am on my third Input card in the last month. This is on my safety circuit which contains 7 solid state switches. The backplane seems fine and I do not see any cracks in the switches. Has anyone come accross a similar problem?
