Multifunction counter/timer module (QD65PD2)
●Channel isolated pulse input module QD60P8G
This module is appropriate for the measurement of input pulse counts (related to speed, revolution, instantaneous flow rate, etc.) and the measurement of quantities (length, cumulative flow, and so forth). The QD60P8G operates on a 10 ms control cycle, thus the minimum value refresh time is 10 ms. The count cycle setting can be changed to the desired time for cumulative count values and moving average pulse counts (sampling pulse counts).
Model  QD60P8G  

Number of channels  8 channels  
Count input signal  Phase  1phase input 
Signal level  5 V DC/12...24 V DC, ≥ 4 mA
