TR2439 ifm electronic Temperature Evaluation Unit with Display

Technical Description: ifm electronic TR2439

The ifm electronic TR2439 is a sophisticated temperature evaluation unit designed for the precise monitoring and processing of signals from Pt100 and Pt1000 temperature sensors. This unit serves as a bridge between high-precision process sensors and the control system, providing a local alphanumeric display for real-time monitoring and IO-Link communication for advanced digital integration. It is widely used in cooling circuits, hydraulic units, and pasteurization processes.

Advanced Signal Evaluation and IO-Link

The TR2439 converts resistance signals from Pt sensors into digital data and switching outputs. Featuring a 4-digit alphanumeric display, it allows operators to check current temperature values on-site. The integrated IO-Link interface enables remote parameterization and transmits diagnostic data, making it a critical component for Industry 4.0 infrastructures. It supports two independent switching outputs or one switching and one analog signal, providing high flexibility for system designers.

Key Technical Characteristics

  • Part Number: TR2439.
  • Sensor Input: Pt100 or Pt1000 (standard).
  • Measuring Range: -100 to 600 °C (depending on sensor).
  • Operating Voltage: 18…30V DC.
  • Output Function: 2x switching (PNP/NPN) or 1x switching + 1x analog.
  • Communication: IO-Link interface.
  • Display: Red/Green 4-digit alphanumeric.
  • Protection: IP67.

Operational Benefits and Safety

The TR2439 is engineered for reliability in demanding industrial environments. The housing is made of high-quality stainless steel and PBT, ensuring high chemical resistance. The two-color display can be configured to change color (e.g., from green to red) when a temperature threshold is exceeded, providing immediate visual warnings to the maintenance team. Its high measurement accuracy of ± 0.3 K (for the electronics) ensures precise process control even in critical thermal applications.
