The time relay lets you delay an output switching on or off, or leave it switched on for a certain time.
The time relay has two types that you can configure under “select used times”.
Delay switching on/off
If the input is true, the output is only set to true after the selected ON time delay. If the input jumps from true to false, the output is set to false after the selected OFF time delay.
Switch on delay and duration
This enables the option “input as flank”. If you have not activated this option, then the input must be true for at least the switch on delay time in order for the output to be set true for the defined duration and after this duration (independently of the input) reset to false. If you have activated this option then a flank is sufficient on the input and the output is set to true for the defined duration and then reset to false.
