NO NC Contact in PLC - Make and Break Contacts in Switches

WebThis “open” virtual contact interrupts virtual power to the virtual coil Q0.1, causing the normally-closed virtual contact M1.0 to “close,” sending virtual power to virtual coil Q0.1. When this virtual output coil “energizes,” the real-life output channel of the PLC activates, sending real power to the alarm light to turn it on, signaling a high-pressure alarm condition.
