The Mitsubishi PLC Extension Module FX2N-2AD / FX2N-4AD is a critical analog input expansion for the FX2N and FX2NC PLC families, delivering exceptional 12-bit resolution on up to four isolated channels. Designed for precision process control, these modules convert voltage (0–10V) or current (4–20mA) signals into digital values for real-time monitoring and closed-loop regulation. With a scan time of only 0.08 ms per basic instruction and a robust 8000-step program capacity, the FX2N system ensures deterministic performance even when integrating multiple analog inputs. Below are the full technical specifications for the FX2N-2AD / FX2N-4AD and its supporting PLC platform.
