Digital counter has 4 digit display, 4 kinds of up/down input modes, DC 12V/24V external power supply.

Features:

• Digital counter accuracy: 0.01%, minimum resolution: 0.0001.
• Input/output signals photoelectric isolated, anti-interference ability.
• Input: 4 kinds of input modes, a variety of input signals, various waveform pulse, grating, proximity sensors, photoelectric sensors, contact switches, encoders, etc. (NPN, PNP).
• Output: 8 kinds of output modes to select, up to 3 segments control output, suitable for various control requirements.
• 4 digit display, has external power supply DC 12V/24V/30mA especially for sensor.
• Standard RS232 or RS485 MODBUS RTU communication, can be directly connected with computers, PLC or other equipments.

Selection table:

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.

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.
