Keyence KV-N24ATP Programmable Controller

Keyence KV-N24ATP Programmable Controller

Product Introduction

The KV-N24ATP is a terminal-block type programmable controller in the Keyence KV Nano series. Specifically, the "P" suffix identifies source (PNP) transistor outputs, which sink current to ground and suit sensors and devices wired in positive-common configurations. In addition, the unit packs 14 input points and 10 output points into a single compact chassis. Therefore, machine builders can reduce panel size and wiring time on small machines. The KV-N24ATP also accepts up to 8 expansion units through its backplane, so users can grow the system to 256 I/O points when production needs change.

Technical Specifications

This controller runs on a supply voltage of 100 to 240 VAC with a tolerance of +10%/-15%. As a result, it connects directly to standard industrial mains without an external transformer. Besides, it delivers a 24 VDC output power supply rated at 0.6 A for powering sensors and small loads. The output circuits use MOSFET transistors in source (PNP) configuration, rated at 30 VDC and 0.5 A per point. Consequently, these solid-state outputs switch faster and last longer than mechanical relays in high-frequency applications.

Processing and Programming

Program capacity is 8k steps, with a basic instruction speed of 50 ns minimum and an application instruction speed of 170 ns minimum. Moreover, this throughput keeps scan times short even when the program includes data handling and comparison logic. Users program the KV-N24ATP with Expanded Ladder, KV Script, or mnemonic instructions through Keyence KV STUDIO software.

Positioning and Counting

For motion tasks, the KV-N24ATP supplies 2 axes of positioning pulse output at up to 100 kHz. Meanwhile, the high-speed counter block supports 2 points of 32-bit auto-reset counting at 100 kHz single-phase or 50 kHz phase-difference input. These functions cover encoder feedback, speed measurement, and simple stepper or servo indexing.

Communication and Expansion

A built-in RS-232C modular port handles KV STUDIO programming and no-protocol serial links to barcode readers or other devices. Furthermore, optional communication modules can be mounted on the backplane when the application needs additional serial channels or network connectivity.

Mechanical and Environmental Parameters

The KV-N24ATP operates from 0 to +55°C without freezing and tolerates 5 to 95% RH without condensation. Storage temperature ranges from -25 to +75°C. The unit resists vibration at 5–9 Hz with 3.5 mm amplitude and 9–150 Hz at 9.8 m/s² intermittently, plus shock of 150 m/s² for 11 ms in three axes. In addition, noise immunity meets IEC standards at 1500 Vp-p, and insulation resistance stays at 50 MΩ or higher at 500 VDC. The unit weighs approximately 0.47 kg, and Keyence confirms active production status.

Installation Guide

First, secure the KV-N24ATP to a DIN rail or a flat panel using the mounting holes. Next, wire the 100–240 VAC supply to the power terminals and confirm a solid ground connection. After that, connect input devices to the 14 input terminals and load devices to the 10 output terminals, following the source (PNP) wiring convention. Besides, leave ventilation clearance around the housing and keep signal wires apart from power cables. Finally, plug the RS-232C cable into a PC running KV STUDIO to download and test the program.

FAQ

Q1: What does the "P" in KV-N24ATP mean?
The "P" indicates source (PNP) transistor outputs. These outputs supply positive voltage to the load, which differs from the sink (NPN) outputs of the KV-N24AT.

Q2: How many I/O points can the KV-N24ATP support in total?
The base unit offers 14 inputs and 10 outputs. With up to 8 backplane expansion units, the system reaches 256 I/O points excluding the base unit's own I/O.

Q3: Which software programs the KV-N24ATP?
Keyence KV STUDIO is the standard tool. It supports ladder editing, simulation, and program transfer over the built-in RS-232C port.

Q4: Can this PLC control two axes of motion?
Yes. The KV-N24ATP provides 2-axis pulse output at up to 100 kHz, enough for simple stepper or servo positioning.

Q5: How do you ship the KV-N24ATP?
We ship each unit through Fedex, UPS, or DHL. Protective foam and a sturdy carton guard the controller against transit damage.
