The high speed counter can count the CH maximum pulse signal of 100kHz starting from
-2147483648 to 2147483647 (32 bits).
Some high speed counters are single-phase counters that have one input terminal and ohter are 2-phase counters that have two input termanils. Depending on the counter type, the relevant features and termanal No. to allocate differ as shown below. For more information on the single-phase counters and 2-phase counters, please see below.
