KCV
Single Preset Counters for Addition and Subtraction/Total Counters for
Addition and Subtraction
30 Hz/10 Hz (with Dipswitch selected)
High-speed
200 Hz/1 kHz (with Set-up Mode selected)
A preset counter that aggregates counts with
functions that provide a large, two-color LED for
display that is easy-to-read in a small DIN48x48 body.
Dual output of predicted output and preset output can
be set with settings for predicted output.
Merits
●Large, easy-to-see display
A large LED for display with character height of 12 mm (4 digits)
and 10 mm (6 digits) is used in a small DIN48x48 body.
12mm
●Easy operation
Setting and changing of preset values with individual setting keys
has the feel of digital switches.
●User configurabe digit number
User can configure the no. of digit.
●Battery-less memory retention
EEPROM is used to retain values in memory, so there is no need
for battery maintenance.
●Removable terminals
Maintenance has been reduced via terminals that can be removed.
After wiring, the terminal cover provides a safe surface for worry-
free use.
●Tamper proof
Key protection can be set for individual keys to prevent
tampering.
●Power source for a large-capacity sensor (AC
P/S type only)
You can source the power for sensor from the built-in P/S 24VDC,
60mA.
●Free power supply for the AC type
The operating AC voltage is wide as 85VAC〜264VAC.
●Various types of counts
[Prescaling]
・The input pulse can be converted to any values and displayed.
[Dual phase addition/subtraction by individual input]
・The counting range can be from positive to negative.
10mm
However, settings are in the positive range.
[Addition-Subtraction]
・Counts can be selected for positive or negative display.
●Dual output with alarm output
Dual setting is possible with alarm output.
Alarm values are values prior to reaching preset values.
●High-speed response with 10 kcps
The input response frequency for this class is a maximum of 10
kHz. Input operational speed can be adjusted to switch to 30, 200,
1 k, or 10 kHz.
●IP65
Membrane is used to protect from operation with wet or dirty
hands, A special cover is also provided as an option to enhance the
protective structure.
●Designed in compliance with CE and UL
CE Mark
B-5
