The Mitsubishi Q68AD-G is a high-performance analog-to-digital (A/D) conversion module designed for the MELSEC Q Series of Programmable Logic Controllers (PLCs). This module is engineered to receive analog voltage or current signals from field instruments (such as sensors and transmitters) and convert them into high-resolution digital values for processing within the CPU. It is a critical component for industrial automation applications requiring precise monitoring and control of process variables like temperature, pressure, flow, and level. The Q68AD-G offers high accuracy, fast conversion speeds, and robust reliability, making it suitable for complex and demanding industrial environments.
