    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 positioning and speed regulation of elevator
    The leveling signal of elevator is obtained by the position sensors installed in the elevator well. When there are many floors, the number of such signals is large, and there are certain difficulties in equipment installation and maintenance. At the same time these signals take up a lot of PLC input port. If using PLC and high-speed counter for positioning, it can not only solve these problems, but also can achieve frequency control of elevator.
    When the elevator is running, digital counter completes the counting work driven by the optical encoder. When the elevator car rises, digital counter counts up. When the elevator car goes down, digital counter counts down. The current value of the counter is the exact position of the car in the elevator well. In this way, the accurate positioning of the elevator is realized. This positioning method has the following functions: It realizes the floor digital display of the elevator lobby and car, determines the running direction, and determines the braking time of leveling.

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

    Digital counter for calculating cloth length
    We use the digital counter with 6 digit to calculate the length of the cloth. We have a lot of questions in the process of installation and debugging, and the customer service staff answers us carefully. Now the digital counter works well. The length calculated by the digital counter is very accurate.

    Very accurate
    The up/down digital counter has good quality and high accuracy. It is very simple to operate and easy to install. We have used it for a long time, the counting function is still very accurate. We are also satisfied with fast delivery and tight packaging.

    Digital counter measure number of motor rotations
    Can we connect your digital counter to proximity sensor so that they can measure the number of motor rotations?
    From: Bryan | Date: 09/04/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, you can choose the digital counter with the Function C (number/length) to count numbers. We recommend that you use a photoelectric sensor or a rotary encoder to measure high-speed rotating motors. If you want to measure the rotational speed of the motor, we suggest you choosing another model ATO-DIGC-FA6D Frequency/Rev/Speed Digital Counter.

    Slot Type Photoelectric Sensor

    Slot-type photoelectric sensor is also known as U-type photoelectric sensor. It's a type of through beam photoelectric sensor and easier to align through beam. Slot type photoelectric sensor can distinguish opaque objects, with power supply DC 12V-24V (6-36V), small installation space, reverse power protection.

    Through Beam Photoelectric Sensor

    Through beam photoelectric sensor consists of a light projector and a light receiver, both of which are separated in structure. The supply voltage is DC 12V-24V or AC 110V-220V. Infrared photoelectric sensor can distinguish the opaque reflective object, with long effective detection distance 5/15/50m, less susceptible to interference, long life, and high reliability.

    Retro-reflective Photoelectric Sensor

    Retro-reflective photoelectric sensor consists of light projector and light receiver in one, has long effective distance range with the help of reflective board. The supply voltage is DC 12V-24V (6-36V) or AC 110V-220V (90-250V). Infrared photoelectric sensor can distinguish the opaque reflective object, with less susceptible to interference, fast reaction, long life, high resolution and high reliability.
