FX5-8AD 8-Channel Analog Input Module Pt100/Ni100/K/J/T/B/R/S | Mitsubishi

The Original New Mitsubishi FX5-8AD is an 8-channel multi-input analog input module for the MELSEC iQ-F series, designed to handle a versatile mix of analog signals including voltage, current, thermocouple, and RTD temperature sensors. With a single module covering 8 analog inputs across multiple signal types, it simplifies system design by reducing the need for separate dedicated modules. The module features a wide input range, high-resolution 1/32000 conversion, and a spring clamp terminal block for tool-free wiring. It is an ideal solution for machine automation, process control, and temperature monitoring applications requiring flexible and precise analog signal acquisition.

Core Engineering Highlights:
8 analog input channels (voltage, current, thermocouple, RTD) | 1/32000 conversion resolution (16-bit signed binary) | Voltage inputs: 0–10V, 0–5V, 1–5V, -10 to +10V | Current inputs: 0–20mA, 4–20mA, -20 to +20mA | Thermocouple types: K, J, T, B, R, S | RTD types: Pt100, Ni100 | Conversion speed: 1 ms/channel (voltage/current), 40 ms/channel (thermocouple/RTD) | Spring clamp terminal block | 8 occupied I/O points | 24V DC external power supply | 0°C to +55°C operating temperature | Approx. 0.3 kg weight
