Basic unit Expansion I/O units

Smallest PLCs in the world

The KV-10 (with 10 I/Os) is about the same size as three
general-purpose relays. The KV-80 (with 80 I/Os) is as small
as a VHS videotape. KV Series PLCs require little space on a
control panel.

Several expansion options available to
increase the number of I/Os

Up to 4 expansion units can be added.

With the KV Series, it’s easy to expand the number of I/Os. To
achieve the input/output ratio that suits your needs, KV-16E or
KV-8E expansion units can be added in any combination of 3
to the KV-80 or KV-40. Any combination of 4 expansions units
can be added to the other models.

Analog I/O units with 12-bit resolution

The KV-DA4 (D/A connector) and KV-AD4 (A/D converter) with
4 channel I/O are available.

Support software for Windows

®

The new Ladder Builder support software enables a program
to be debugged on a PC screen without connecting a PLC or
other device.

Interrupts and counters

The interrupt input instruction receives pulse signals as short
as 25 µs regardless of the program cycle time, thus allowing
real time processing.
The KV Series also provides two 10 kHz counters that are
suitable for counting pulses with a high frequency.

Convenient analog timer

Useful during startup, the analog timer trimmer enables the
adjustment of the values for timers and counters, in real time,
based on actual operating conditions, with a range from 0 to

249. There are 2 analog timers in the KV-80, KV-40, and
KV-24, and 1 in the KV-16 and KV-10.

20 kHz clock pulse output (KV-80)

The 20 kHz clock pulse output enables positioning at varying
speeds. The KV Series is useful as a pulse generator for
stepping motors.
(The KV-10/16/24/40 has a maximum clock frequency of
2 kHz.)

Other useful features

• Built-in 1 ms timer

• Memory capacity of up to 3000 steps
(500 steps: KV-10/16)

• Serial communication function

• Relay replacement is possible. (KV-80R, KV-16EYR)

• Programs are stored in EEPROM, eliminating the need for
backup battery.
