Digital counter has 4 digit display, 4 kinds of up/down input modes, DC 12V/24V external power supply.Features:
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.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.Mode C: Up/down (addition and subtraction)INA counts up, INB counts down.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.Wiring diagram:Tips: Digital counter application in industrial productionIn 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.
