Super-small Programmable Logic ControllersKV447y DescriptionConvenient analog timerThe KV-10 (with 10 I/Os) is about the same size as threegeneral-purpose relays. The KV-80 (with 80 I/Os) is as smallas a VHS videotape. KV Series PLCs require little space on acontrol panel.KV-10Useful during startup, the analog timer trimmer enables theadjustment of the values for timers and counters, in real time,based on actual operating conditions, with a range from 0 to249. There are 2 analog timers in the KV-80, KV-40, andKV-24, and 1 in the KV-16 and KV-10.PLCsSmallest PLCs in the world20 kHz clock pulse output (KV-80)The 20 kHz clock pulse output enables positioning at varyingspeeds. The KV Series is useful as a pulse generator forstepping motors.(The KV-10/16/24/40 has a maximum clock frequency of2 kHz.)The KV-10 can be mounted in two-thirds thespace required by conventional 10 I/O PLCs.Several expansion options available toincrease the number of I/OsExample of trapezoidal control(ramp up/down control)20 kHz max. (frequency)1500Up to 4 expansion units can be added.500Basic unitExpansion I/O unitsI/O 4 each8 inputs16 inputs8 outputsTimeSpeed- Constant Speedupspeeddowntimetimetime16 outputsBuilt-in DisplayVisual V-16EXKV-300KV-16EYT/RKVWith the KV Series, it’s easy to expand the number of I/Os. Toachieve the input/output ratio that suits your needs, KV-16E orKV-8E expansion units can be added in any combination of 3to the KV-80 or KV-40. Any combination of 4 expansions unitscan be added to the other models.Analog I/O units with 12-bit resolutionOther useful featuresThe KV-DA4 (D/A connector) and KV-AD4 (A/D converter) with4 channel I/O are available. 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 forbackup battery.Support software for Windows The new Ladder Builder support software enables a programto be debugged on a PC screen without connecting a PLC orother device.* Windows is a registered trademark of Microsoft Corporation of U.S.A.(America).Interrupts and countersThe interrupt input instruction receives pulse signals as shortas 25 µs regardless of the program cycle time, thus allowingreal time processing.The KV Series also provides two 10 kHz counters that aresuitable for counting pulses with a high frequency.TECHNICAL GUIDE : P.779CAD DATA Download : www.keyence.com/CADGwww.keyence.com447

Super-small Programmable Logic ControllersInstruction selection windowUNDO functionThe user-friendly design allows data entry from a keyboard ora mouse. You can select and specify a device or commandfrom a list provided by device type.This ensures error-free entry of target symbols. For fastprogramming, you can also enter the symbol directly by typingthe command from the keyboard.The Ladder Builder for KV enables efficient editing. If youaccidentally delete an instruction, you can undo the actionsimply by clicking the “Undo” button. “Redo” button cancels“Undo”.KV449PLCsAuto-save functionUsage listWhen creating Ladder diagrams, it can be difficult to keeptrack of addresses already used. The usage list displayswhich ones are used/available.The Ladder Builder for KV automatically backs up yourprogram at predetermined intervals. This protects your datafrom being lost due to PC power loss or system crash.Built-in DisplayVisual KVAnalog-I/OKLCompactKV-300y SimulatorKVQuick debugging without a PLCForward/reverse single step executionEven without a PLC connected, the Ladder Builder for KV cansimulate program execution. The execution can be checkedwithout transferring the program to the PLC. By providing asingle-step execution function (forward or reverse) in additionto a regular scan execution function, debugging efficiency isincreased.You can easily find a problem in complex operations bychecking the operation process one step at a time.Ladder Simulator enables direct checkingof the ladder diagram executionBy clicking an element in the ladder diagram, the simulatorscreen quickly appears, allowing element setting/resetting.Monitors All functionTimers, counters and data memories can be checkedsimultaneously in multiple windows. For effective debugging,you can check devices at one time, which don’t directlyappear in the ladder diagram.Registration MonitorThe Ladder Builder for KV can display multiple timing chartsof any devices simultaneously. This enables convenientchecking of all element on/off timing.y MonitorReal time monitoring without stopping the machineLadder diagram and element on/off stands can be monitored real time.Timing charts can be monitored simultaneously.TECHNICAL GUIDE : P.779CAD DATA Download : www.keyence.com/CADGwww.keyence.com449
