Functional Description:
The Timer Delay operator triggers its output upon expiration of a user-defined delay period. The operator can be configured to function as either an "ON Timer" or an "OFF Timer".
When configured as an "ON Timer", the output y will switch from LOW to HIGH d seconds after input switches from LOW to HIGH and remains HIGH for at least d seconds:

When configured as an "OFF Timer", the output y will switch from HIGH to LOW d seconds after input switches from HIGH to LOW and remains LOW for at least d seconds:

The delay time d can be dynamically adjusted via input or fixed by operator property Delay Value. If input is connected the operator property value is ignored.
