The Mitsubishi Electric Q68RD3-G is an 8-channel temperature input module for the MELSEC-Q PLC platform, engineered for precise RTD measurement in industrial automation, process control, and energy applications. Supporting Pt100, JPt100, and Ni100 sensors, it enables reliable, scalable temperature monitoring in distributed I/O architectures and compact control panels.

Designed for seamless integration on the Q-series backplane, the module provides consistent, noise-robust signal acquisition for RTD inputs while keeping engineering and maintenance straightforward. With 0.54 A internal current consumption and a slim 27.4 mm width, it simplifies panel power budgeting and space planning, and its CE, UL/cUL, and UKCA certifications plus marine class approvals (ABS, BV, DNV GL, LR, NK, RINA) support deployment in global machine building and maritime control systems.

Choose the Q68RD3-G to standardize temperature measurement across your MELSEC-Q installations, reduce commissioning time, and ensure dependable operation throughout the lifecycle, with the added assurance of a 1-year warranty that protects your investment during integration and service.
