The FX2N-4DA is a special‑function analog module for Mitsubishi FX series PLCs. It provides up to four output channels that convert digital signals to voltage (‑10 V to +10 V) or current (0 mA to 20 mA) with 12‑bit resolution.
The guide covers mechanical dimensions, power requirements, I/O point usage, buffer‑memory configuration, programming examples, I/O characteristic adjustment, and error‑checking procedures. It also lists environmental ratings and safety precautions for reliable integration into automation systems. This manual is written in Chinese.
| Resolution | 12 bits |
|---|---|
| Voltage output range | -10 V to +10 V DC |
| Power consumption | 5 V, 30 mA |
Up to eight special modules can be connected in order No.0 to No.7 on a single FX2N unit.
The module consumes 5 V at 30 mA from the PLC’s internal power supply or an active expansion unit.
Use the FROM command to read the error status registers for detailed error information.
The analog conversion has a 12‑bit resolution, giving a voltage step of about 5 mV.
