The Mitsubishi Electric FX2N-4AD analog input module expands MELSEC-FX2N PLC systems by providing four programmable A/D input channels that convert voltage or current signals into digital data for control. Each channel supports voltage input from -10 to +10 V DC or current input within 4–20 mA (±20 mA), delivering 12-bit resolution with an approximate 15 ms conversion time per channel. The module occupies 8 expansion I/O points on the bus, is powered from the PLC's 5 V DC supply (about 30 mA), and communicates via buffer memory exchange with the PLC CPU for reliable data handling. Weighing around 0.3 kg and IP20 protected, it mounts as a PLC expansion module (DIN rail/base unit connection) in industrial panels and expansion racks, supporting applications such as temperature monitoring, pressure sensing, flow measurement, and level control where precise analog input is required. Common replacements include Mitsubishi FX3U-4AD, FX2N-2AD, and Allen-Bradley 1762-IF4. Show more
