KCN-S / KCN-W
Merits
Single / Dual Preset Counters for Addition and Subtraction.
With the DIN standard size of only 48 mm by 48 mm, the full featured counter
incorporates an easy to read LCD display.
Integrating the latest technologies, the counter can be used for many purposes
as measuring quantities, length and time. Other options include single preset for
general purpose models, and dual preset setting for multifunction counters.
Small body and easy to see display
With its body of only 48 mm by 48 mm, the counter provides full
screen display of either four-digit or six-digit numbers with the
height of 13 mm or 10 mm.
Backlit LCD integrated in all models
Displayed values are backlit to facilicate reading in darkness.
Keypad protection cover
A keypad cover is attached to prevent erroneous operation.
DC power as thin as 55 mm
With minimum space requirement, the control board can be
installed anywhere.
Easy operation
Countup values can be set or modified independently from initial
settings. Changes can be made easily and quickly on site.
A series of models to meet all your needs
All 16 models include advanced functions such as prescaling
and decimal display. These models can be combined
appropriate to satisfy your requirements.
Multifunction
A complete series of models provide advanced functions such
as dual preset nine output modes, count disable, large capacity
sensor power (DC 24V, 60 mA) and AC 100 to 240V user-
selectable power source.
Timer option
The KCN-4S general purpose 4-digit counter can be used also
as a precise digital timer.
Addition, subtraction or both operations are available.
Twelve error codes quickly report error status.
EEPROM to avoid cell replacement
The counter uses an EEPROM to eliminate the use of cells. The
memory can store all counts, preset values and mode settings.
Water proofed front panel
The keypad on the front panel is completely coated (IP64) to
insulate dust and water.
30cps, 1kcps, 2kcps or 5kcps
(selected by digit keys)
