FX5-4AD-ADP 4-Channel Analog Input Adapter 14-bit 24V DC | Mitsubishi

The Original New Mitsubishi FX5-4AD-ADP is a 4-channel analog input expansion adapter for the MELSEC iQ-F series, designed to add high-precision analog measurement capability to FX5U, FX5UC, FX5UJ, and FX5S CPU modules. Each of the 4 channels is independently configurable for voltage (–10 to +10V DC) or current (–20 to +20mA DC) signals with 14-bit binary resolution. The adapter connects to the left side of the CPU module and supports programless data transfer — no dedicated instructions are required. With 14-bit resolution, ±0.1% accuracy, and fast conversion up to 450 µs, it delivers reliable analog signal acquisition for industrial automation, process control, and machine monitoring applications.

Core Engineering Highlights:
4 analog input channels (voltage/current configurable) | –10 to +10V DC voltage range (1 MΩ input resistance) | –20 to +20mA DC current range (250 Ω input resistance) | 14-bit binary digital output | 625 µV to 1250 µV voltage resolution / 1.25 µA to 2.5 µA current resolution | ±0.1% accuracy at 25°C (±0.2% over 0–55°C) | 450 µs max conversion speed | Photocoupler isolation between input terminals and PLC | 0 occupied I/O points | 17.6 mm width | 0.1 kg weight | 0°C to +55°C operating temperature
