Description:

When Input TRG is Status 1, Output Q is changed at once to Status 1. When Input TRG is changed from 1 to 0 (when the descending edge comes), the internal time delay timer of MiniPLC is activated and Output Q is still remained in Status 1.

When the set time T is up, Output Q becomes 0 and the timer is reset l .

If Input TRG changes from Status 1 to Status 0 again, the timer is activated again.

Before the set time T is up, the timer and output can be reset via R (Reset) input.

This function is applicable to the lighting of staircase, the control of barriers in park, the control of water throttling valve, etc.

The assignment range of T is 0.01 ~ 99.99, and the time units can be set respectively to hour (H), minute (M) and second (S). Its time accuracy can reach 0.5% S.
