Hello,
I used the TCT201-2ABC counter to read an input from a flow meter with aound 20 pulses per second.
By connecting the flowmeter to the counter and at the same time to a fast entry PLC I noticed that there is a big difference.
168 pulses in the PLC corresponds to 53 pulses in TCT201 although I put the input frequency (inF.1)to the maximum. I need to know if the counter has a frequency limit F <20HZ?

Hi,
the max frequency of the digitals input is 100Khz and there isn't limits for the min frequency.
How did you connect your digital input counting signal to TCT201-2ABC? Are you sure that by connecting the input together with your PLC there is no electrical noise interfering with the counting? Can you post the parameterization of your TCT201-2ABC and the electrical connections you have used?

Best regards.
