The Mitsubishi FX3U-4AD is an analog input extension module designed for the FX series of programmable logic controllers (PLCs). It operates with a dual power supply configuration: DC5V 110mA (internally supplied by the PLC) and DC24V 90mA (externally supplied).

This module provides 4 analog input channels, each independently configurable for either voltage or current input. The supported input ranges include:

●Voltage input: DC -10 to +10V

●Current input: DC -20 to +20mA or 4 to 20mA

With a compact form factor measuring 55mm × 90mm × 87mm and a weight of approximately 0.2kg, the module is designed for space-efficient installation.

Key features of the FX3U-4AD include:

●High-speed AD conversion at 500µS per channel

●Built-in digital filter function for noise reduction

●Peak hold function for capturing signal maximum values

●Flexibility for mixed input types across channels (voltage or current per channel)

The module is compatible with FX3GA, FX3G, FX3GE, and FX3U series PLCs. When connecting to FX3GC or FX3UC series PLCs, an additional interface adapter—such as the FX2NC-CNV-IF or FX3UC-IPS-5V—is required.

Overall, the FX3U-4AD offers versatile and high-performance analog signal acquisition for industrial automation applications, enabling precise monitoring and control of voltage and current signals.
