Mitsubishi Electric Q68DAI Analog Input Module

The Mitsubishi Electric Q68DAI Analog Input Module is an 8-channel analog input interface for MELSEC-Q PLC systems, converting field sensor signals into PLC data. It mounts in a MELSEC-Q rack slot and supports voltage and current signals (model dependent, e.g., 0–10 V, 4–20 mA) with high‑resolution A/D conversion and industrial analog input accuracy (platform dependent); it also includes status LEDs for module health and overvoltage/transient protection (platform dependent). Widely used for distributed I/O expansion and process monitoring in manufacturing and process control environments—HVAC systems, chemical and water treatment plants, batching processes, and material handling equipment—where sensor feedback like temperature, pressure, and flow is fed to PLC logic for monitoring and regulation.
