The Mitsubishi FX3U-3A-ADP is an analog input/output adapter designed for the FX3 series programmable logic controllers (PLCs). It features two analog input points and one analog output point, providing a compact and cost-effective solution for analog signal processing. The unit weighs approximately 0.1 kg, making it lightweight and easy to integrate into control panels.

This adapter supports analog voltage inputs in the range of DC 0 to 10V and current inputs of DC 4 to 20mA for both input channels. Similarly, the single analog output channel can be configured for either voltage output (DC 0 to 10V) or current output (DC 4 to 20mA). Each channel can be independently set to accept either current or voltage signals, offering flexibility for various sensor and actuator requirements.

One of the key advantages of the FX3U-3A-ADP is that it requires no special programming to operate with FX3 series PLCs, simplifying installation and reducing setup time. However, when connecting to FX3SA, FX3S, FX3GA, FX3G, or FX3U main units, a conversion adapter or function extension board is necessary to ensure proper compatibility and communication. This adapter is ideal for applications requiring basic analog I/O capabilities without the need for additional, more complex analog modules.
