Frequency Threshold Trigger

The output is switched on and off depending on two frequencies which can be specified.

The threshold trigger measures the signals at input Fre. The pulses are captured across a measuring interval which can be specified. If the frequency measured within the measuring interval higher than the input frequency, the output Q is switched to “Hi”. Q is switched again to “Lo” when the measured frequency has reached the value of the output frequency or if it is lower.

Adjustable parameters

                On frequency:         0,1 ... 10 pulses/sec        (6)

                Off frequency:         0,1 ... 10 pulses/sec        (2)

                Time interval:         0,1 ... 100 s         (5)
