Ladder Diagram Example​


When the open contacts, M95.3 and M33.1, are powered OFF, the coil Y10.2 is deenergized.



When the open contact, M95.3, is powered ON, the coil, Y10.2, is energized.



Or when the open contact, M33.1, is powered ON, the coil, Y10.2, is energized.


If both open contacts, M95.3 and M33.1, are powered ON, the coil, Y10.2, is energized.
