2. Key Selling Points

1. Integrated Smart Temperature Sensor – Easy Installation & Reliable Wiring:The TN2531 is a fully integrated temperature transmitter with built-in Pt100/Pt1000 sensing element and signal conditioning electronics. Features M12 plug-in connection for plug-and-play operation, minimizing wiring errors and accelerating commissioning.

2. High-Precision Temperature Measurement – Up to 1/5 B Accuracy:Utilizes high-stability platinum RTD elements with accuracy up to Class B (±0.3 °C @ 0 °C) or optional 1/3 B and 1/5 B ultra-high precision, ensuring reliable and accurate data in critical process applications.

3. IO-Link Digital Communication – Enables Smart Connectivity & Remote Configuration:Equipped with IO-Link interface (V1.1 or higher) for bidirectional communication. Allows remote access to real-time temperature, device status, diagnostics, and enables parameter setting, unit selection, and calibration—ideal for Industry 4.0 and digital process management.

4. Dual Output: Analog + Digital – Compatible with Legacy and Modern Systems:Provides both 4–20 mA or 0–10 V analog output and IO-Link digital output, enabling seamless integration into traditional control systems as well as modern fieldbus networks—perfect for system upgrades and flexible automation.

5. Configurable Output Functions – NO/NC and Analog Mode Selection:Both outputs can be freely configured as switching signals (NO/NC selectable) or analog outputs, supporting alarms, control logic, and monitoring—reducing the need for multiple sensors.
