Multifunction Preset Counter
H7CX
Counters
• Highly visible display with backlit negative transmissive LCD.
• Programmable PV color to visually alert when output status
changes (screw terminal block models).
• Intuitive setting enabled using ergonomic up/down digit keys (4digit models) and DIP switch.
• Configurable as 1-stage counter, 2-stage counter, total and preset counter, batch counter, dual counter, or tachometer. (Configurability varies with model.)
• PNP/NPN switchable input.
• Finger-safe terminals (screw terminal block models).
• Meets a variety of mounting requirements:
Screw terminal block models, and pin-style terminal models.
• NEMA4/IP66 compliance.
• Six-language instruction manual.

CP1, CP2
• In general (except for dual counter mode)
Reads counting signals
Increment, decrement, command, individual, and quadrature inputs accepted.
• When used as a dual counter
Reads CP1 count signals with CP1 input and CP2 count signals with CP2 input.
Increment signals can be input.
Reset or Reset 1
• In general (except for dual counter mode)
Resets present value and outputs (OUT2 when using the batch counter). (See note 1.)
Counting cannot be performed during reset/reset 1 input.
The reset indicator is lit during reset input.
• When used as a dual counter
Resets the CP1 present value (to 0).
Counting for CP1 input cannot be performed during reset 1 input.
The reset indicator is lit during reset 1 input.
Total Reset or
Reset 2
(See note 2.)
• When used as a 1-stage/2-stage counter
Does not operate (Not used).
• When used as a total and preset counter
Resets the total count value.
Holds the total count value at 0 during total reset input.
• When used as a batch counter
Resets the batch count value and batch output (OUT1).
Holds the batch count value at 0 during reset 2 input.
• When used as a dual counter
Resets the CP2 present value.
Counting for CP2 input cannot be performed during reset 2 input.
OUT1, OUT2
Outputs take place according to designated output mode when corresponding preset is reached.
Note: 1. In increment mode or increment/decrement mode, the present value returns to 0; in decrement mode, the present value returns to the
set value with 1-stage models, and returns to set value 2 with 2-stage models.
2. The reset indicator will not be lit when the total reset or reset 2 input is ON.
Using as a Tachometer
Inputs
Outputs
CP1, CP2
Reads counting signals. (CP2 input is not used.)
Reset 1, Reset 2
Holds the measurement value and outputs. (Reset 2 input is not used.)
The reset indicator is lit during hold.
OUT1, OUT2
Outputs signals according to the specified output mode when a set value is reached.

Note: 1. The mounting panel thickness

2. To allow easier operability, it is
recommended that Adapters are
mounted so that the gap between
sides with hooks is at least 15 mm
(i.e., so that the panel cutout interval
is at least 60 mm).
3. It is possible to mount counters
side by side, but only in the
direction without the hooks.
If they are mounted side-by-side,
water-resistant specifications
cannot be ensured.

Hard Cover
Y92A-48
Note: 1. Depending on the operating environment, the condition of
the Soft Cover may deteriorate, and it may shrink or become
harder. Therefore, it is recommended that the Soft Cover is
replaced regularly.
2. The H7CX’s panel surface is water-resistive (conforming to
IP66) and so even if drops of water penetrate the gaps between the keys, there will be no adverse effect on internal
circuits. If, however, there is a possibility of oil being present
on the operator’s hands, use the Soft Cover. The Soft Cover
ensures protection equivalent to IP54F against oil. Do not,
however, use the H7CX in locations where it would come in
direct contact with oil.

Precautions
■ Transistor Output
The service life of the output relays depends on the switching
capacity and switching conditions. Consider the actual application
conditions and use the product within the rated load and electrical
service life. Using the product beyond its service life may result in
contact deposition or burning.
The transistor output of the H7CX is isolated from the internal circuitry by a photocoupler, so the transistor output can be used as both
NPN and PNP output.
NPN output
Do not disassemble, repair, or modify the product. Doing so may
result in electric shock, fire, or malfunction.
Do not allow metal objects or conductive wires to enter the product.
Doing so may result in electric shock, fire, or malfunction.
Load
Load
+
+
Power for load
Power for load
The diode connected to the collector of the output transistor is used
to absorb inverted voltage that is generated when an inductive load is
connected to the H7CX.
■ External Power Supply
The capacity of the external power supply is 100 mA at 12 V. When
using a 24 VAC/12 to 24 VDC power supply, reduce the load with the
power supply voltage, as shown in the following diagram (DC power
supplies only).
