What is a timer?
A timer is a simple automation component which is used to manage actions over a period of time or control how long actions last.The timer is a control device which triggers an action according to a time and a function. After a predefined time has elapsed, the timer
closes or opens one or more contacts.
Timing cycles, whether single shot or repetitive, are started by latching inputs or pulsed inputs, allowing a wide variety of functions to be created.
To execute which actions?
A timer can be used to trigger an action according to a predefined time. It can also be used to stagger actions over a period of time.
In any time-related application, the timer can play a role and can be used to:
