    C: DC 5V
    I0: Two pulse inputs (encoder);
    I1: INA (one input for switching input)

    Digital counter up/down input modes:
    Mode A: Up (addition)
    INA counts up. INB is GATE function. When INB is high level (or shorted with +12V), INA input is forbidden.
    Digital counter up down mode a
    Mode B: Up/down (addition or subtraction)
    INA counts up. INB is count-down control function. When INB is high level, INA turns count-up into count-down.
    Digital counter up down mode b
    Mode C: Up/down (addition and subtraction)
    INA counts up, INB counts down.
    Digital counter up down mode c
    Mode D: Up/down (for encoder)
    INA signal leads INB signal (count-up). INA signal lags INB signal (count-down). It is often used for encoder or grating input.

    Tips: Digital counter application in industrial production
    In industrial production, it is often necessary to automatically count product quantity. Digital counters are the best choice. Digital counters have the advantages of visual display and accurate counting. It has several counting trigger modes, which are determined by the actual using condition and environment. Digital counters are generally divided into contact counters and non-contact counters, of which non-contact counters with photoelectric sensor are most widely used.
    Counter with photoelectric sensor uses photoelectric sensor to form photoelectric gate, and counts objects passing through the photoelectric gate in real time. Digital counter can effectively control the number of packages in the production line through real-time monitoring, achieve automatic control, save labor costs, and efficiently complete production.

    In this video, ATO will show you how to wire a digital counter. And how to set the basic parameters of digital counter.
