How to wire the DH48J counter

1. First of all, you need to determine the power supply end, as shown in the figure below.

2. If you use a proximity switch.

or photoelectric switch, then the switch brown wire (some are red) is connected to the instrument 12V (some are marked as VCC or U0), the blue wire is connected to the instrument GND (some are marked as COM), and the black wire is connected to the IN terminal (some are marked as CNT). If a two-wire mechanical contact switch is used, then the two wires should be connected to the IN and GND ends mentioned above, as shown in the figure below.

The 8-pin has no power output and cannot be used directly with a proximity switch unless you use an external 24VDC (or 12VDC) power supply. I also bought an 11-pin one, and I can connect the proximity switch.

Counter wiring method:

First of all, determine the power terminal, if you use a proximity switch or photoelectric switch, then the switch brown wire (some are red) connected to the instrument 12V (some are marked as VCC or U0), the blue wire is connected to the instrument GND (some are marked as com), and the black wire is connected to the IN terminal (some are marked as CNT); If a two-wire mechanical contact switch is used, then the two wires should be connected to the IN and GND terminals mentioned above.

Introduction: counting is the simplest basic operation, the counter is the logic circuit that realizes this operation, the counter is mainly counting the number of pulses in the digital system, in order to realize the function of measurement, counting and control, and has the function of frequency division, the counter is composed of the basic counting unit and some control gates, and the counting unit is composed of a series of various triggers with the function of storing information, these triggers have RS triggers, T triggers, D triggers and JK triggers.

1. First of all, you need to determine the power supply end, as shown in the figure below.

2. If you use a proximity switch or a photoelectric switch, then the brown wire of the switch (some are red) is connected to the instrument 12V (some are marked as VCC or U0), the blue wire is connected to the instrument GND (the one with a shape is marked as COM), and the black wire is connected to the IN terminal (some are marked as CNT). If the mechanical contacts of the two wires are used to open the branches, then the two wires should be connected to the In and GND ends mentioned above, as shown in the figure below.

The steps for wiring the DH48J counter are as follows:

1. First determine the power supply end.

2. If you use a proximity switch or photoelectric switch, then the brown wire of the switch (some are red) is connected to the instrument 12V (some are marked as VCC or U0), the blue wire is connected to the instrument GND (some are marked as COM), and the black wire is connected to the IN terminal (some are marked as CNT). If a two-wire mechanical contact switch is used, then the two wires should be connected to the IN and GND terminals mentioned above.

Counting is the simplest and most basic operation, the counter is the logic circuit that realizes this operation, the counter is mainly to count the number of pulses in the digital system, so as to realize the function of measurement, counting and control, and at the same time has the function of frequency division.

The counter is composed of a basic counting unit and a number of control gates, and the counting unit is composed of a series of various triggers with the function of storing information, such as RS trigger, T trigger, D flip-flop and JK flip-flop.

Summary. Wiring method of the power supply and travel switch of the DH48J preset number counter Power wiring of the preset number counter Connect the power supply 2 and 7 of the DH48J preset number counter to the AC 380V power supply. Wiring method between the preset number counter and the travel switch The counting pins 1 and 3 of the DH48J preset number counter are connected to the normally open contacts of the travel switch, respectively.

In this way, when a moving part collides with the travel switch, its normally open contact closure causes the DH48J preset counter to count once.

Wiring method of power supply and travel switch of DH48J preset number counter Pre-delay the power wiring of which set number counter Connect the power supply 2 and 7 of the DH48J preset number counter to the AC 380V power supply. Wiring method between the preset number counter and the travel switch The counting pins 1 and 3 of the DH48J preset number counter are respectively connected to the normally open contact of the travel switch. In this way, when the moving parts collide with the travel switch, its normally open contact closure causes the DH48J preset counter to count once.

After powering on, the set counting value must be rented to press the panel reset button Zheng He; Otherwise, the given count value is invalid. Compared with the door, the XOR door has an output, which can operate the next step, or you can call the type to clear zero.

There is a terminal function mark next to the relay. Pin 2,7 is the power input. The use of normally open or normally closed contacts depends on the function of use.

8 Pin Counter Pin Connected Power Pin Input Equivalent to one pulse for each short pin is displayed, which is displayed as 1

Pin 1 and pin 3 do not add voltage, there is a pulse signal on it.

8 Pin Counter Pin Connected Power Pin Input Equivalent to one pulse for each short pin is displayed, which is displayed as 1

Pin 1 and Pin 3 can no longer be voltaged, there is a pulse signal on it.

Counting is a kind of simple and basic operation, the counter is the logic circuit that realizes this operation, the counter is mainly counting the number of pulses in the digital system, so as to realize the function of measurement, counting and control, and has the function of frequency division at the same time, the counter is composed of the basic counting unit and some control gates, and the counting unit is composed of a series of various triggers with the function of storing information, these triggers have RS flip-flop, T flip-flop, D flip-flop and JK flip-flop, etc. Counters are widely used in digital systems, such as counting the instruction address in the controller of the electronic computer, so that the next instruction can be taken out sequentially, the number of additions and subtractions is recorded when multiplying and dividing in the combinator, and the counting of pulses in digital instruments, etc. The counter can be used to show the working status of the product, and is generally used to indicate how many copies of the product have been folded and folded.

Its main indicator is the number of digits of the counter, which is common with 3 digits and 4 digits. Obviously, a 3-digit counter can be displayed up to 999, and a 4-digit counter can be displayed up to 9999.

You can only connect a phase wire or neutral wire at pin 8, and then lead a wire to your appliance at normally closed pin 5 or normally open pin No. 6.

In general, you can't normally open and close the foot to add voltage, that can only play the role of a switch, the same as the temperature control meter.

Just get an intermediate relay for the counter control.
