PLC Training

If it is a relay then it is not energized. If it is a switch, then it is off. If it is a high limit such as a temperature alarm then the current temperature is below the limit. Normally open - Is a contact that does not flow current in its normal state. Energizing it and switching it on will close the contact, causing it to allow current flow.

NO SPST Relay

The NO Normally-Open SPST (Single Pole Single Throw) relay has an opened circuit state when no current is applied to its coil so basically it disconnects the power to the load in the inactive state. When current is applied to its coil the generated magnetic field switches the armature and closes the contact so you can say that it turned ON the load (fan, light bulb, etc).
