Safe speed monitoring with the 480 041 H… speed monitor

Speed monitor 480041H…


Speed monitoring of machines and drives

 

Speed monitor 480041H… is used for monitoring rotational movements on, e.g., machines and drives to ensure safe operation.

It also allows safe access to the machine once it has been brought to a standstill. Additionally, an overrun can be monitored after the drives are switched off.

 

  • Standstill and rotational speed monitoring can be monitored from the one device.
  • 4 safe transistor outputs
  • Up to SIL 3 / PL e
  • Adjustable monitoring frequency depending on variant of 0.1 to 9.9 Hz or 0.5 to 99 Hz
  • Maximum input frequency 2 kHz
  • The rotary code switch enables simple installation and reduced installation time.
  • 2 signalling outputs and LEDs for simple diagnostics
  • Setup mode through safely reduced speed without additional
  • accessories such as DIP switches
  • Guarding access through speed monitoring
