Product Description

​The KEYENCE KV-N14AR is a compact, AC-powered programmable logic controller (PLC) from the KV Nano series, designed for small-scale automation applications. It features 8 DC inputs and 6 relay outputs, offering a total of 14 I/O points in a space-saving form factor. The controller supports programming in expanded ladder logic, KV Script, and mnemonic languages, with a program capacity of 8,000 steps. It also includes high-speed input capabilities with a response time of 2 µs and a high-speed output frequency of 100 kHz. The KV-N14AR is equipped with a built-in RS-232C serial port for communication and offers a 24 VDC output power supply with a capacity of 0.6 A. Its robust design ensures reliable performance in environments with temperatures ranging from 0°C to 55°C and humidity levels between 5% and 95% RH.​
