Product Description

The **Mitsubishi Q68TD-G-H01** is a **Melsec Thermocouple Module** designed for the **Q Series Temperature Input** system, supporting 8 channels for thermocouple signals (K, J, R, S, etc.). It integrates seamlessly with Q-series PLCs via the high-speed **MELSECNET/H** or **Q bus interface**, ensuring real-time data accuracy. Operating at **24 VDC ±10%**, it functions reliably within **0–55°C** (operating) and **-25–75°C** (storage). Ideal for industrial automation, manufacturing, and energy sectors, this module excels in precise temperature monitoring for processes like chemical reactors or furnace control. Key strengths include robust noise immunity, configurable cold junction compensation, and easy scalability. However, it requires compatible Q-series base units and lacks onboard isolation. Sensor compatibility defines detection ranges, typically spanning **-200–1800°C** depending on thermocouple type. No built-in battery or display, emphasizing its role as a dedicated input module.
