The IFM TR2439 is a high-quality temperature transmitter designed to interface with Pt100 and Pt1000 resistance temperature detectors (RTDs) in industrial applications. By combining flexible sensor compatibility, IO-Link communication, and robust electrical design, the TR2439 provides engineers and operators with a reliable and efficient solution for precise temperature monitoring and integration into automation networks.

One of the standout features of the TR2439 is its IO-Link interface, which enhances traditional temperature monitoring with smart functionality. IO-Link enables remote configuration, advanced diagnostics, and transparent communication with higher-level control systems. This allows operators to not only receive accurate temperature signals but also benefit from predictive maintenance insights and simplified sensor management—hallmarks of Industry 4.0-enabled systems.

The TR2439 is built for compatibility with both Pt100 and Pt1000 elements, two widely used standards for precision temperature sensing. This versatility means operators can deploy the transmitter across multiple applications and systems without needing separate models for different RTD types. It provides flexibility in system design while maintaining accuracy and reliability across a broad spectrum of temperature monitoring tasks.

The device incorporates a G 1/2 external thread process connection, offering a secure, leak-free, and standardised interface for integration into industrial piping or equipment. The use of gold-plated contacts ensures excellent electrical conductivity and long-term resistance to corrosion, guaranteeing stable signal transmission and reducing maintenance over time.

Engineered with robust electrical specifications, the TR2439 operates within an 18…32 V DC supply range and complies with cULus Class 2 source requirements, ensuring safety and compliance in North American industrial installations. Its low current consumption of less than 50 mA makes it energy-efficient while supporting reliable performance during continuous operation. With a protection class III rating, the device provides additional assurance of electrical safety in industrial environments.

Compact and easy to install, the TR2439 is ideal for industries such as food and beverage, chemical processing, HVAC, and water treatment—applications where accurate, stable, and efficient temperature monitoring is critical. By bridging high-accuracy RTD sensing elements with modern automation networks, the TR2439 supports system optimisation and long-term operational reliability.

In summary, the IFM TR2439 combines IO-Link connectivity, versatile RTD compatibility, and robust electrical design in a compact and reliable transmitter. With gold-plated contacts, secure process connection, low power consumption, and smart integration capabilities, it is an excellent choice for engineers seeking a dependable solution for precise temperature measurement in industrial automation.
