MITSUBISHI FX3U-4DA PLC, FX3U Analog Output Module 16 Bit 4 Analog Outputs

The Mitsubishi FX3U‑4DA is a special‑function analog output expansion module for MELSEC‑F FX3U / FX3UC series PLC systems. It converts digital values calculated by the PLC CPU into standard industrial analog voltage or current signals, to drive external field devices such as frequency inverters, proportional valves, servo drives and regulators. It connects to the right‑side expansion bus of FX3U CPU unit, delivers 4 independent analog output channels. Each channel can be set to voltage or current mode separately, supporting closed‑loop process control, speed adjustment and set‑point output for small‑medium automation equipment.

• 4 independent configurable channels: Each channel freely selectable for voltage output (-10~+10V) or current output (0‑20mA /4‑20mA), flexible for multi‑device control.
• High‑precision D/A conversion: 16‑bit high‑resolution output, stable signal for demanding process applications.
• Multiple built‑in functions: Buffer memory (BFM) parameter configuration, output hold function, limit alarm and table output function for easy programming.
• Strong anti‑interference performance: Isolated circuit design, suitable for noisy industrial cabinet environment.
• Simple installation: DIN‑rail mounting, quick bus connection with FX3U base unit, occupies 8 I/O points on PLC system.
• Wide operating temperature: 0~+55℃, with CE certification for global machine export projects.

• Packaging machinery: control proportional valves, variable‑speed drives for filling & labeling equipment
• Water & wastewater treatment: adjust flow / pressure regulating valves
• General OEM automation: assembly machines, test benches, material conveyor lines
• Plastic & rubber machinery: speed control for extruder auxiliary drives
• Textile & food machinery: multi‑parameter analog set‑point control
• Production‑line retrofitting & upgrade projects
