KV-N14AT Keyence KV Nano PLC 8 In/6 Out All-in-One Controller

Keyence KV-N14AT KV Nano Series All-in-One PLC – Compact Control with Built-In I/O

Core Technical Specifications

• Brand: Keyence
• Model: KV-N14AT
• Series: KV Nano
• Program capacity: 8k steps for ladder logic and KV Script programs
• Execution speed: Basic instructions reach 50 ns minimum, application instructions reach 170 ns minimum
• Program language: Expanded ladder, KV Script, and mnemonic formats
• Built-in I/O: 8 input points and 6 output points on the base unit

Positioning and High-Speed Counter Performance

• Two positioning pulse output axes run at a maximum frequency of 100 kHz
• Two high-speed counter points offer 32-bit auto-reset operation
• Single-phase counting reaches 100 kHz, while phase difference counting reaches 50 kHz
• These features support precise motion tasks such as stepper and servo positioning

I/O Expansion Capability

• The backplane accepts up to three expansion units for flexible system growth
• The system supports a maximum of 128 I/O points excluding the base unit
• Users can add digital I/O, analog modules, and communication modules as needed
• This expansion path keeps the initial investment low while preserving room for growth

Communication Interfaces

• A built-in RS-232C port uses a modular connector for easy wiring
• The port supports KV STUDIO programming and no-protocol serial communication
• Backplane communication modules add fieldbus and network connectivity options
• This design suits both standalone machines and networked production lines

Electrical and Output Ratings

• The supply voltage range covers 100 to 240 VAC with +10%/-15% tolerance
• A 24 VDC output power supply provides 0.6 A capacity with +/-10% tolerance
• Outputs use MOSFET transistor sink (NPN) type at 30 VDC and 0.5 A per point
• The wide AC input range suits global power environments without extra transformers

Environmental Durability and Physical Data

• Operating temperature spans 0 to +55 °C without freezing
• Storage temperature spans -25 to +75 °C for safe transport and storage
• Relative humidity ranges from 5 to 95% RH without condensation
• The unit weighs approximately 0.42 kg and carries no specific protection rating
• Keyence confirms active production status on the official product page as of September 2026

Installation Guide

• Mount the unit on a DIN rail or a flat panel inside a control cabinet
• Keep the enclosure free from condensation and maintain ambient temperature within 0 to +55 °C
• Wire the 100–240 VAC supply to the dedicated power terminals with proper grounding
• Connect input devices to the 8 input terminals and output loads to the 6 MOSFET terminals
• Use the 24 VDC output supply for sensors that draw up to 0.6 A total
• Attach expansion units to the backplane before applying power
• Configure programs through the RS-232C port with KV STUDIO software

Packing List

Frequently Asked Questions

• Q: What is the difference between the KV-N14AT and larger KV Nano models?
  A: The KV-N14AT offers 8 inputs and 6 outputs on the base unit, while larger models add more onboard I/O. All KV Nano units share the same programming environment.
• Q: Can I expand the I/O beyond 14 points?
  A: Yes. The backplane supports up to three expansion units and reaches 128 I/O points excluding the base unit.
• Q: What positioning speed does this PLC support?
  A: Two pulse output axes run at up to 100 kHz, which suits many stepper and servo positioning tasks.
• Q: Which power supply does the unit require?
  A: The unit accepts 100 to 240 VAC with +10%/-15% tolerance and also provides a 24 VDC 0.6 A output supply.
• Q: What is the operating temperature range?
  A: The controller operates from 0 to +55 °C without freezing and stores safely from -25 to +75 °C.
• Q: How do I program the controller?
  A: You program the unit through the RS-232C port using KV STUDIO software with ladder, KV Script, or mnemonic languages.
• Q: What is your stock and shipping policy?
  A: We keep brand-new original stock on hand and ship within 5 days via DHL, FedEx, or UPS. We support returns within 30 days.
