Keyence KV-N14AT PLC Controller 8-In 6-Out

Keyence KV-N14AT PLC Controller – Compact Control for Small Machines

The KV-N14AT brings reliable logic control to small automation projects. Keyence designed this KV Nano unit as a terminal-block type controller. It offers 8 input points and 6 transistor output points on a single housing. Engineers use it for packaging machines, assembly stations, and simple test fixtures. Moreover, the built-in RS-232C port connects easily to HMIs and host devices.

Technical Specifications

The KV-N14AT provides an 8k program capacity. Instruction execution starts at 50 ns for basic commands. Application instructions run at 170 ns. Furthermore, the controller supports expanded ladder, KV Script, and mnemonic programming. Two positioning pulse outputs reach 100 kHz per axis. Besides that, two 32-bit high-speed counters handle 100 kHz single-phase or 50 kHz phase-difference signals.

I/O and Communication Details

The base unit includes 8 inputs and 6 outputs. Users can add up to 3 expansion units through the backplane. This raises total capacity to 128 I/O points. Meanwhile, the RS-232C modular connector supports KV STUDIO and no-protocol serial links. Communication modules also expand options via the backplane.

Electrical and Environmental Data

The KV-N14AT accepts 100 to 240 VAC input power with +10%/-15% tolerance. A 24 VDC output supply delivers 0.6 A. Outputs use MOSFET transistors in sink (NPN) mode, rated 30 VDC at 0.5 A per point. Operating temperature ranges from 0 to +55 °C without freezing. Storage temperature spans -25 to +75 °C. In addition, humidity tolerance covers 5 to 95% RH without condensation.

Installation Guide

First, mount the unit on a DIN rail or panel inside a clean enclosure. Next, wire the AC supply to the designated terminals. Then connect input signals and output loads according to the terminal diagram. Keep high-voltage cables away from signal lines to reduce noise. Finally, set the communication parameters in KV STUDIO and run a test program.
