Keyence KV-N40ATP AC Power PNP Transistor PLC

Keyence KV-N40ATP Programmable Logic Controller

The KV-N40ATP belongs to the Keyence KV Nano series. This terminal block type PLC serves as a versatile base unit for medium automation tasks. Engineers select this model when they need direct AC power connection and source-type transistor outputs. Its design saves panel space while delivering fast instruction execution.

Technical Specifications

The processing power of this unit meets demanding industrial needs. Basic instruction execution takes only 50 ns, while application instructions require a minimum of 170 ns. Furthermore, the program capacity reaches 16k steps, which provides ample room for complex logic sequences. The controller supports expanded ladder, KV Script, and mnemonic programming languages.

Built-in I/O and High-Speed Features

The base unit includes 24 input points and 16 output points. Outputs use MOSFET transistor technology with a source (PNP) configuration. Each point handles up to 30 VDC at 0.5 A. For motion control tasks, the KV-N40ATP provides 3 axes of positioning pulse output. The maximum output frequency reaches 100 kHz, enabling precise control of stepper or servo drives. Additionally, two high-speed counter inputs handle 32-bit auto-reset operation at 100 kHz single phase or 50 kHz phase difference.

Communication and Expansion

A built-in RS-232C port (modular connector) supports KV STUDIO programming and no-protocol serial communication. Moreover, the system accepts up to 8 expansion units through the backplane. This scalability allows the total I/O count to reach 256 points, excluding the base unit. Therefore, the controller grows with your application requirements without a full replacement.

Mechanical and Environmental Parameters

The unit operates on a 100 to 240 VAC supply with a tolerance of +10%/-15%. An output power supply delivers 24 VDC at 0.6 A capacity for external loads. It functions reliably in temperatures from 0 to +55 °C without freezing. Storage temperature ranges from -25 to +75 °C. Relative humidity stays within 5 to 95% RH without condensation.

Installation Guide

Mount the KV-N40ATP on a standard DIN rail or directly onto a panel surface using mounting holes. First, ensure the power supply is disconnected before wiring. Next, connect the AC power lines to the designated terminals. For output wiring, use the source configuration to drive loads. Always separate high-voltage power lines from signal lines to minimize electrical noise. Finally, verify all connections before applying power.
