Mitsubishi A/D CONVERTER UNIT Q68ADI FREE

Description:

The Mitsubishi A/D Converter Unit Q68ADI FREE is an analog‑to‑digital signal interface module used in PLC and automation systems to convert analog field signals into digital data for processing by the controller. Commonly installed in Mitsubishi PLC racks and distributed I/O configurations where precise analog signal acquisition is required. Maintenance teams and system integrators use this unit for replacement, retrofit, and system expansion to support reliable measurement and control of analog inputs.

Applications:

The Q68ADI FREE A/D converter unit is used in industrial automation to monitor process variables such as temperature, pressure, level, flow, and other analog signals. It is deployed in manufacturing lines, water/wastewater treatment systems, HVAC controls, packaging machines, and process plants where analog sensors must be interfaced with the PLC. With accurate conversion and isolation, it supports real‑time data acquisition for process control and monitoring.
