This device, also called INTEGRAL TIMER, accumulates the sum of the time for the periods where the IN input is in assert state. This means that the computed time is the sum of the ON times of the IN input.
If the computed sum reaches the programmed time, applied to the PT input, the Q output become TRUE.
At this point, the only way to reset the integral timer can be performed asserting the R ( RESET ) input.
The ET output pin reports the current elapsed time.

Description |
IN |
The timer accumulates the time when this input is TRUE |
|
|
R |
The integral timer may be resetted using this input |
|
|
PT |
To this input user must apply the programmed time. User should use an IDENT object to enter a time constant |
|
|
Q |
After that the pre-programmed time threshold is reached, this output become TRUE |
|
|
ET |
This output reports the current elapsed time |
