Understanding the FCT18-Ata Timing Function
The FCT18-Ata features an ON-delay timing function with pulse summation capability, making it ideal for applications requiring cumulative timing:
Ata: ON-delay with Summation Control
When the control input (S) receives pulses, the timer accumulates the duration of all valid pulses. The timing diagram illustrates how multiple input signals (t1, t2, t3, …, tx) are summed together, with the output relay (R) activating when the total accumulated time (T = t1 + t2 + … + tx) is reached. This feature is particularly valuable in processes where multiple events need to trigger a response based on their cumulative duration.
