Configured for precise thermal monitoring, the Mitsubishi Electric Q68TD-G-H01 delivers eight channel-isolated thermocouple inputs to high-reliability MELSEC Q Series control environments. This high-performance module is designed to eliminate ground loops and reduce noise interference in multi-point temperature measurement applications, making it highly suitable for demanding industrial processing plants. Each channel can be configured independently, allowing for versatile sensor integration across different thermocouple types within a single PLC rack footprint.

The Q68TD-G-H01 offers upgraded channel-to-channel isolation compared to non-isolated temperature modules such as the standard Q64TD. When replacing older non-isolated versions, review rack power budgets, as the internal 5 VDC current consumption is significantly higher (0.49 A) due to the onboard isolation circuitry. Ensure your system's power supply module (e.g., Q61P) has sufficient remaining overhead.
To prevent measurement drift in environments subject to rapid ambient temperature fluctuations, avoid mounting the module directly adjacent to heat-producing components like power supplies or motor starters inside the enclosure. Ensure that unused input channels are software-disabled in the module parameters to prevent false sensor wire-breakage alarms and unnecessary CPU diagnostics.
Always use dedicated thermocouple extension and compensation cables matching the thermocouple type (e.g., KX extension wire for Type K sensors). Keep these sensor wires routed away from high-voltage AC cables and variable frequency drive outputs to minimize electromagnetic induction. Ensure shield wires are terminated at a single, clean instrumentation ground point near the PLC rack.
Hook the bottom tab of the Q68TD-G-H01 module securely into the mounting slot of the MELSEC Q series base unit.
Pivot the module flush against the base plate and tighten the top securing screw to the specified torque rating to ensure solid ground plane contact.
Wire the thermocouple leads directly to the module terminals, maintaining strict attention to physical polarity indications (+ and - markings).
Configure the hardware configuration utility within your programming software (GX Works2 or GX Works3) to recognize the module and download parameter changes to the CPU.
