clem k posted:penn station posted:The relay board in Clem's picture is very neatly laid out. The power flows from bottom to top with four similar circuits. A close up of the relays in each of the three rows and a shot of the back would probably be sufficient to work out the circuit. My first question is what to the toggle switches do?
Toggles turn the system off
There are 4 switches at the bottom of photo.
So to be clear, does each switch turn off (i.e., force OFF) 1 of the 4 blocks irrespective of the shutdown feature of your system?
And those are the ONLY switch/configuration controls to your "Safety Relay" system?
We're trying to help the OP here! In absence of diagrams/schematics/parts-lists from your custom built system since the OP wants what you have, I think we can get there if you let us know exactly what your system does. In my opinion that is...
