H7BR
Teaching for the Set Value 1
1. Press the MODE key to teach for set value 2 (on double
preset model only).
2. Input the count signal from external sensor.
3. Press the TEACH key to register the present count value as
the set value.
• The set value is displayed by teaching while pressing the
TEACH key.

First and second outputs of
double preset model
Reset operation at SET = 0
Reversible D, E, and F input modes
Permissible limits of count speed
One-shot output time
Contact form of single preset models
Precautions
EXTERNAL POWER SUPPLY
The capacity of the power supply from the counter is 160 mA at
12 V or 80 mA at 24 V. For models with 24 VAC/12 to 24 VDC
specifications, loads must be established between the following
limits.
H7AN
H7AN-WE executes the first output followed by
the second output.
The order of first and second outputs executed
by H7AN-W depends on the first and second
output set values; whichever is closer to the
primary counting value takes precedence, and
the corresponding output is executed first.
Outputs when reset input is OFF.
Yes
Up to 505 over setting, e.g., 50 cps for
30 cps counting speed
Approximately 0.1 to 1 s
SPDT

Teaching for the Set Value 2 (double preset model only)
• Set the same operation as before. (Press the DISPLAY
key to return from teaching mode to run mode.)
H7BR
First and second outputs are executed
in no particular order by H7BR.
No output is made when reset input is
OFF.
No. (Possible to compensate the
count value with compensation input.)
Limited to 10% max. over setting
10 to 1,000 ms
SPST-NO
POWER SUPPLIES
An unstable region is generated whenever the power supply is
turned on or off. Although these regions vary depending on the
power supply voltage and load conditions, they will fall within
the limits shown below.

A switching regulator is used in the counter's internal circuits,
causing rush current to flow when power is turned on. If the
capacity of the power supply to the counter is insufficient, the
counter may not start operation. Be sure the power source
meets the current consumption requirements of the counter.
Connect the power supply voltage through a relay or switch in
such a way that the voltage reaches a fixed value immediately.
