Mitsubishi FX3U-4DA-ADP MELSEC-F 4‑Channel Analog Output Adapter

Mitsubishi Electric FX3U‑4DA‑ADP is an analog output adapter for the MELSEC‑F FX3U series PLC system. It connects to the left side of the CPU module and provides four independent analog output channels. Each channel is configurable for voltage output (0‑10 V DC, ±10 V DC) or current output (4‑20 mA DC). Data transmission does not require dedicated instructions, simplifying integration.

Applications:

• Speed reference control for variable frequency drives and servo motors

• Positioning of proportional valves and electric actuators

• Process control signal generation for temperature and pressure regulation

• Analog instrument interfacing in factory automation and OEM equipment

Technical Specifications:
