FX3U-4DA 4-Channel Analog Output Module 16-Bit | Mitsubishi

The Original New Mitsubishi FX3U-4DA is a 4-channel analog output module from the MELSEC-F FX3U series, designed for high-precision analog signal generation in compact machine control and industrial automation systems. Each channel can be independently configured for voltage (-10 to +10 V DC) or current (0 to 20 mA DC, 4 to 20 mA DC) output, providing flexible control of variable frequency drives, proportional valves, actuators, and other analog field devices. Featuring 15-bit + sign resolution for voltage and 15-bit resolution for current, the module delivers precise signal generation for process control and monitoring applications. The FX3U-4DA communicates with the PLC via buffer memory (BFM) and connects through a screw-clamp terminal block.

Core Engineering Highlights:
4 analog output channels (voltage/current, per-channel configurable) | Voltage: -10 to +10 V DC (15-bit + sign, 0.32 mV resolution) | Current: 0 to 20 mA / 4 to 20 mA (15-bit, 0.63 µA resolution) | Occupies 8 I/O points | 5 V DC 110 mA (internal) + 24 V DC 90 mA (external) power supply | 55 × 90 × 87 mm | 0.2 kg
