I have L1 from 120 AC wired into the com for the relay outputs 12, 13, 14 and 15. Number 12 and 13 have become permanently stuck on. There is only a light 125XBRIRGA120AB from Edwards signaling hooked to it. I can't imagine this is pulling very much. Why are my relays stuck permanatly closed now. When connected in Connected Components Workbench and go to Global variables and click the Logical value for those ports I see the light on the plc for that port light up but no click. Can switching these too fast on and off break them? I have a Red Lion G304K hooked to it and 2 push buttons on the screen to turn the plc global variable on and off.
