The Mitsubishi FX2N-5A is a specialized analog input/output expansion module designed for use with Mitsubishi FX series programmable logic controllers (PLCs). It features 4 analog input channels and 1 analog output channel, making it suitable for applications requiring both measurement and control of analog signals.

The module supports a wide range of input voltage signals, including an ultra-low voltage range of -100 mV to +100 mV. This capability eliminates the need for external signal converters or amplifiers when handling low-level signals such as those from thermocouples, strain gauges, or other micro-voltage sensors.

The FX2N-5A offers high-resolution analog-to-digital conversion with 15-bit binary plus 1 sign bit for input channels, and 14-bit binary plus 1 sign bit for the output channel. This ensures precise measurement and accurate control signal generation.

Each of the four input channels can be independently configured for different input ranges, providing flexibility to accommodate various sensor types and signal levels within a single module. The module also includes built-in input filtering, internal arithmetic processing, and scaling functions, which allow users to perform signal conditioning, linearization, and engineering unit conversion directly within the module, reducing the programming load on the PLC CPU.

When used with FX3GC or FX3UC series PLCs, the FX2N-5A requires an additional interface adapter, such as the FX2NC-CNV-IF or the FX3UC-1PS-5V, to ensure proper connection and power supply compatibility.

Overall, the FX2N-5A is a compact and versatile analog expansion module that enhances the analog processing capabilities of Mitsubishi FX series PLCs, particularly in applications involving low-voltage signals and multi-range measurement requirements.
