FAQ for H7CC-AU

What is the difference between H7CC-AU and H7CC-A8D?
The H7CC-AU is a screw-terminal unit on AC100-240 V with multifunction counter and tachometer (1-stage + 2-stage + total + batch + dual + double + tachometer). The H7CC-A8D is an 8-pin socket plug-in on AC24 V / DC12-48 V with simpler 1-stage + total counter only. Pick AU for a screw-wired multifunction device on AC mains; pick A8D for a quick-swap 24 VDC socket device with only basic counter.
Can the H7CC-AU read a tachometer as well as a counter?
Yes. Switch the function from counter to tachometer in the parameter menu, set the pulse-period or pulse-width measurement mode, and enter a prescale value. Maximum input frequency is 10 kHz in 1-input mode (5 kHz in other modes). The 6-digit display shows the speed directly in engineering units (rpm, m/min) once prescaling is set.
Does the H7CC-AU keep its count through a power loss?
Yes. The H7CC-AU uses non-volatile memory with 100,000 rewrite cycles minimum and 10-year data retention without power. On power restore, the count resumes from the retained value. Preset values, output-mode settings, and the prescale factor are all retained as well, so no reprogramming is needed after a brownout.
