y Description

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. KV-10

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.)
Example of trapezoidal control (ramp up/down control)

20 kHz max. (frequency)

The KV-10 can be mounted in two-thirds the space required by conventional 10 I/O PLCs.
Several expansion options available to increase the number of I/Os
Up to 4 expansion units can be added.

KV-8ET/R

KV-8EYT/R

KV-16EYT/R

KV-300 KV
With the KV Series, its 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.

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.

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 s 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.

y Software

The Ladder Builder for KV creates sequence programs in Windows
KV-H6WE2 User-friendly operation and high-level programming capabilities make the Ladder Builder for KV [KV-H6WE2] ideal for beginners and experienced programmers alike.

y Editor

Easy editing using Windows functions Multi-file editing
Multiple files can be edited simultaneously on the Ladder Builder for KV. You can freely cut and paste from one file to another.
Instruction selection window
The user-friendly design allows data entry from a keyboard or a mouse. You can select and specify a device or command from a list provided by device type. This ensures error-free entry of target symbols. For fast programming, you can also enter the symbol directly by typing the command from the keyboard.

UNDO function

The Ladder Builder for KV enables efficient editing. If you accidentally delete an instruction, you can undo the action simply by clicking the Undo button. Redo button cancels Undo.
Auto-save function Usage list
When creating Ladder diagrams, it can be difficult to keep track of addresses already used. The usage list displays which ones are used/available. The Ladder Builder for KV automatically backs up your program at predetermined intervals. This protects your data from being lost due to PC power loss or system crash.

y Simulator

Quick debugging without a PLC
Even without a PLC connected, the Ladder Builder for KV can simulate program execution. The execution can be checked without transferring the program to the PLC. By providing a single-step execution function (forward or reverse) in addition to a regular scan execution function, debugging efficiency is increased.
Forward/reverse single step execution
You can easily find a problem in complex operations by checking the operation process one step at a time.
Ladder Simulator enables direct checking of the ladder diagram execution

By clicking an element in the ladder diagram, the simulator screen quickly appears, allowing element setting/resetting.

Monitors All function

Timers, counters and data memories can be checked simultaneously in multiple windows. For effective debugging, you can check devices at one time, which dont directly appear in the ladder diagram.

Registration Monitor

The Ladder Builder for KV can display multiple timing charts of any devices simultaneously. This enables convenient checking of all element on/off timing.

y Monitor

Real time monitoring without stopping the machine
Ladder diagram and element on/off stands can be monitored real time. Timing charts can be monitored simultaneously.
