Product information

Description

The Siemens 3RS2500-1AW30 is a professional temperature monitoring relay engineered for precise thermal management within industrial automation environments. This device is designed to measure temperatures in solid, liquid, and gaseous media, providing a reliable solution for process control and the protection of motors and plants against overheating. Operating across a versatile voltage range of 24-240V AC/DC, it integrates seamlessly into diverse electrical configurations, ensuring consistent performance and safety in critical control circuits.

Advantages

This temperature monitoring relay offers exceptional flexibility by supporting various sensor types, including Pt100 and Pt1000 resistance sensors, as well as type J and type K thermocouples. The device features an intuitive design that allows for straightforward operation using rotary and slide switches, enabling users to adjust settings such as hysteresis with ease. Its compact 22.5 mm width saves valuable space in control cabinets, while the quiescent current principle ensures reliable monitoring. By providing a dedicated change-over contact, the relay facilitates immediate safety responses when temperature thresholds are exceeded or undershot, effectively preventing equipment damage.

Suitable for

  • Monitoring temperatures in industrial processes
  • Protecting motors and machinery from excessive heat
  • Thermal management of solid, liquid, and gaseous media
  • Integration into automated control systems

When it may not be suitable

This relay is not intended for applications requiring multi-channel monitoring or complex digital communication protocols like IO-Link, as this specific model is designed for single threshold value monitoring. It may also not be suitable for environments where extreme vibration or non-standard electrical interference exceeds the specified operational limits of the device.

Key specifications

  • Voltage range: 24-240V AC/DC
  • Sensor compatibility: Pt100, Pt1000, Thermocouple J, Thermocouple K
  • Width: 22.5 mm
  • Output: 1 change-over contact
  • Functionality: 1 threshold value, overshoot and undershoot monitoring
  • Connection type: Screw terminal

How to use

Installation should be performed by qualified personnel in accordance with local electrical standards. The relay is designed for mounting on standard DIN rails. Connect the appropriate temperature sensor to the designated terminals and wire the change-over contact into your control circuit to trigger the desired safety action. Use the integrated rotary and slide switches on the front panel to configure the required temperature thresholds and hysteresis settings according to your specific application requirements.

What to consider before purchase

  • Verify that your temperature sensor type is compatible with the relay
  • Ensure the control cabinet has sufficient space for a 22.5 mm wide module
  • Confirm that the power supply voltage matches the 24-240V AC/DC range
  • Check if your application requires a single threshold or if a more complex monitoring system is needed
Usage recommendations: Regularly inspect the screw terminal connections to ensure they remain tight and free from corrosion. Periodically test the threshold settings to confirm that the relay triggers the safety response as expected during routine maintenance cycles.
