Digital Counter/Tachometer
H7CC
New and improved design for easier use,
programming, maintenance and user feedback
The improved user interface is intuitive and
offers better overall visibility. Replacement
time notification function notifies the user of
potential preventive maintenance
Basic Features
• The white-color display offers better visual clarity and visibility, and the color universal
design is used.
• Up/Down Keys are provided for all six digits, which reduces the number of button
operations during setup and other processes.
• An easy operation is realized by the operation guide on which each key lights up.
• The progress can be easily understood at one glance from the status indicators
of the present value and the measurement value.
• The body depth of all models with screw terminals has been reduced to 59 mm.
Safety and Reliability
• The replacement time is notified in advance by predicting the service life.
• The power supply circuit and input circuits are isolated in all models, and therefore, there is no need of any wiring restrictions.
Other Features
• Follows the ratings, characteristics, and functionality of the H7CX-N.
• Equipped with the Output Allocation and Output ON/OFF Inversion Function.
• Equipped with a Memory Backup and H7AN Compatibility Function to facilitate problem-free conversion from H7CN/H7AN.

Basic Features
Better visual feedback and operation
The white-color display offers better visual clarity and visibility, and
the color universal design is used. The keys of all six digits can be
operated up/down for easier use. The LED indicator of the operable
keys lights up to support setup.
Status Notification by Status Indicator
The status can be indicated by the ratio of the present value or measurement
value to the set value, which makes it easy to understand the status.
Shortened Body
The body depth of all models with screw terminals has been reduced
to 59 mm, which contributes to thinner control panels!
Safety and Reliability
Notification of Replacement Time
The service life prerequisites of the counter include the relay output
count and the deterioration of the electrolytic capacitors. In the H7CC,
in addition to the relay output count, an alarm is displayed when the
deterioration of electrolytic capacitors due to the cumulative run time
reaches the standard value, and planned maintenance is supported.
Note:
For details, refer to
Replacement Time Notification Function
on
pages 41 and 57.
Isolated Power Supply and Input Circuits
In all models, the power supply circuit and input circuits are isolated.
Previous non-isolated counters had wiring restrictions and could be
damaged if wired incorrectly. The H7CC removes these worries.
