Mitsubishi Q68RD3-G Temperature Input Module for MELSEC-Q Series

The Mitsubishi Q68RD3-G (Q68RD3-G) is a channel-isolated temperature input module designed for use with MELSEC-Q series programmable logic controller systems. As part of the MELSEC-Q automation platform, this module connects directly to resistance temperature detector sensors, converting analog temperature readings into digital values for automated monitoring and regulation. It installs onto a standard MELSEC-Q base unit, enabling seamless data exchange with the central processing unit across the high-speed system bus. Engineered for industrial process control, the Q68RD3-G supports critical temperature measurement tasks across manufacturing lines, thermal processing machinery, and environmental test chambers. Its isolated channel design reduces electrical interference in demanding factory environments, ensuring stable data acquisition and dependable operational accuracy. The unit serves as a reliable replacement module for routine maintenance and control panel retrofits, helping sustain long-term system uptime and performance.
