Mitsubishi Electric Q68ADV Analog Voltage Input Module

The Mitsubishi Electric Q68ADV is an 8-channel analog voltage input module for Mitsubishi Q Series PLCs, designed to convert and process field-sensor signals for precise monitoring and control. It mounts in a Q Series rack and connects via the backplane bus, accepting analog voltage inputs (0–10 V or model-dependent) with a high-impedance input design and sequential sampling for reliable data capture. Key specifications include MPN Q68ADV, IP20 protection, operating temperature 0–55 °C, storage -20 to 70 °C, and model-dependent resolution and accuracy. Typical applications are temperature monitoring, pressure sensing, flow control, level measurement, process feedback loops, and HVAC system control in industrial automation panels. As a scalable expansion for Mitsubishi Q Series controllers, the module helps expand PLC capabilities and replace or upgrade existing analog input interfaces in environments requiring reliable voltage signal handling.
