Features

  • Universal Low-Voltage Power (WR2): Operates on 24V AC or 24V DC, adapting to any modern low-voltage control environment.

  • Potential-Free Relay Output: Versatile switching contact capable of handling independent signal or power loads.

  • Integrated Fixed Cable (-K): 2-meter factory-sealed cable ensures a high-integrity connection and an IP 67 protection rating.

Applications

  • Control Cabinet Protection: Verifying that 24V cooling fans are actually moving air to prevent overheating of sensitive electronics.

  • Small Exhaust Systems: Monitoring airflow in laboratory fume hoods or localized chemical extraction points.

  • Heater Safety Interlocks: Using the relay to ensure airflow is present before a 24V-controlled heating element can activate.
