Product Description

The Mitsubishi FX3U-4AD is a high-precision analog input module designed for the MELSEC-F (FX3U) series PLCs. It features four 16-bit analog inputs capable of measuring both voltage (-10 to +10 V DC) and current (-20 to +20 mA or 4 to 20 mA DC), with each channel independently configurable for voltage or current input. This module offers a 500 µs per channel high-speed A/D conversion, making it suitable for applications requiring rapid and accurate analog signal processing. Its compact design and robust features ensure reliable performance in various industrial environments.​
