Mounting and Panel-cutout Dimensions Diagram

Mounting Dimensions (Unit: mm)

Front panel dimensions are the same 

for all models.

*These dimensions vary with the 

type of DIN track (reference value).

Surface Mounting

Standard panel cutout is shown in the 

following diagram (conforms to DIN 43700). 

A space of 15 mm or greater (a panel 

cut-out distance of 60 mm or greater) is 

recommended towards the Adapter's 

hook side to enable easier mounting work.

Twin Counter

One-shot output 2 time

One-shot output 2 time

One-shot output 1 time

For details, refer to the latest datasheet (Cat. No. M079).

10) Do not leave the Counter for long periods at a high temperature with output current in the ON state. Doing 

so may result in the premature deterioration of internal components (e.g., electrolytic capacitors).

11) EEPROM is used as memory when the power is interrupted. The write life of the EEPROM is 100,000 

writes. The EEPROM is written when the power is turned OFF or when switching from function setting 

mode or configuration selection mode to run mode.

12) Dispose of the product according to local ordinances as they apply.

13) Attach the front panel when using the Counter. The latches in the middle of each of four sides secure the 

front panel to the main body. To remove the panel, widen the four latches and pull the panel toward you. 

To mount the panel, fit all four latches correctly into the slots on the main body.

1) H7CX models with a 12 to 24-VDC power supply use a transformer-free power supply method in which the power 

supply terminals are not isolated from the signal input terminals. If a non-isolating DC power supply is used, 

unwanted current paths may occasionally burn or destroy internal components depending on the wiring. Always 

check the wiring sufficiently before use. 

2) An inrush current of approx. 10 A will flow for a short time when the power supply is turned ON. If the capacity of 

the power supply is not sufficient, the Counter may not start. Be sure to use a power supply with sufficient 

capacity.  

3) Maintain voltage fluctuations in the power supply within the specified operating voltage range.

Do not allow pieces of metal, wire clippings, or fine metallic 

shavings or fillings from installation to enter the product. Doing so 

may occasionally result in electric shock, fire, or malfunction. 
Minor injury due to explosion may occasionally occur. Do not use 

the Counter where subject to flammable or explosive gas.
Fire may occasionally occur. Tighten the terminal screws to the rated torque. 

H7CX terminals: 6.55 to 7.97 lb-in (0.74 to 0.90 N

m)

P2CF Socket terminals: 4.4 lb-in (0.5 N

m)

Minor injury due to electric shock may occasionally occur. Do not 

touch any of the terminals while power is being supplied. Be sure 

to mount the terminal cover after wiring.

3)  Mounting the Counter side-by-side may reduce the life expectancies of internal components.

4)  Use the Counter within the specified ranges for the ambient operating temperature and humidity.

5)  Do not use in the following locations:

 Locations subject to sudden or extreme changes in temperature.

 Locations where high humidity may result in condensation.

 Locations with excessive vibration or shock. 

 Locations subject to water. 

 Locations subject to oil. 

6)  Do not use the Counter outside of the rated ranges for vibration, shock, water exposure, and oil exposure.

7)  Do not use this Counter in dusty environments, in locations where corrosive gasses are present, or in locations subject 

to direct sunlight.

8)  Install the Counter well away from any sources of static electricity, such as pipes transporting molding materials, 

powders, or liquids.

9)  Internal elements may be destroyed if a voltage outside the rated voltage range is applied.

10)  Separate the Counter from sources of noise, such as devices with input signals from power lines carrying noise, 

and wiring for I/O signals.

11)  Do not connect more than two crimp terminals to the same terminal.

12)  Up to two wires of the same size and type can be inserted into a single terminals.

13)  Use the specified wires for wiring. Applicable Wires: AWG 18 to AWG 22, solid or twisted, copper

14)  Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to 

clearly indicate its function.

15)  When the Counter is operated with no-voltage input (NPN input), approximately 14 V is output from the input 

terminals. Use a sensor that contains a diode. 

16)  Use a switch, relay, or other contact so that the rated power supply voltage will be reached within 0.1 seconds.  

If the power supply voltage is not reached quickly enough, the Counter may malfunction or outputs may be 

unstable.

17)  Use a switch, relay, or other contact to turn the power supply OFF instantaneously. Outputs may malfunction 

and memory errors may occur if the power supply voltage is decreased gradually.

18)  When changing the set value during operation, because the H7CX uses a constant read-in system, output will 

turn ON if the set value is equal to the present value. 

19)  If the set value and present value are both 0, the output will turn ON for the default setting. The output will turn 

OFF during a reset operation.

20)  Do not use organic solvents (such as paint thinners or benzine), strong alkali, or strong acids. They will damage 

the external finish.

21)  Confirm that indications are working normally, including the backlight LED, and LCD. The indicator LEDs, LCD, 

and resin parts may deteriorate more quickly depending on the application environment, preventing normal 

indications. Periodic inspection and replacement are required. 

22)  The waterproof packing may deteriorate, shrink, or harden depending on the application environment. Periodic 

inspection and replacement are required. 

1)  When mounting the Counter to a panel, tighten the two mounting screws alternately, a little at a time, so as 

to keep them at an equal tightness. If the panel screws are tightened unequally, water may enter the panel.

2)  Store the Counter at the specified temperature. If the Counter has been stored at a temperature of less than 

10

°

C, allow the Counter to stand at room temperature for at least 3 hours before use.

Note:

   The location of the DIP switch is shown on the left. 

Also, read the precautions provided on the left.

*1:

After reaching the last set value, the 

U

Key will return to the first set value. 

*2:

When the tachometer input mode is F2 (2 inputs), set tachometer output modes 1 and 2 

     using the 

U

 Key.

*3:

Even if 10 kHz is selected when the tachometer input mode is F2 to F5, the counting 

speed will be 5 kHz.

 When conforming to EMC standards, refer to the information provided in this Instruction Manual for 

cable selection and other conditions.  

 This is a class A product. In residential areas it may cause radio interference, in which case the user 

may be required to take adequate measures to reduce interference. 

 Basic insulation is provided between power supply and input terminals, between power supply and 

output terminals, and between input and output terminals. (No insulation is provided between the 

power supply and input terminals for the H7CX-A

@

D.)

 Basic insulation is provided between power supply and output terminals, and between input and 

output terminals. When double insulation or reinforced insulation is required, apply double insulation 

or reinforced insulation as defined in IEC 60664 that is suitable for the maximum operating voltage 

with clearances or solid insulation. 

 Connect the input and output terminals to devices that do not have any exposed charged parts. 

Conformance to EN/IEC Standards

The life expectancy of the output relay varies considerably according to its 

usage. Use the output relay within its rated load and electrical life 

expectancy. If the output relay is used beyond its life expectancy, its 

contacts may become fused or there may be a risk of fire. Also, be sure 

that the load current does not exceed the rated load current and when 

using a heater, be sure to use a thermal switch in the load circuit.
Minor electric shock, fire, or malfunction may occasionally occur. Do not 

disassemble, modify, or repair the Counter or touch internal components.
