Options

  • MOD bus interface
  • Potential-free alarm contact with connection to an external alarm system
  • Voltage input for externally setting the set point
  • Voltage output for reading the actual value
  • Interface converter/gateway from RS485 to USB or Ethernet
  • Optional direct measurement of the application's temperature with an external gauge; by subsequently setting the set point, greater temperature stability can be achieved than with a standard system
  • stronger pump with higher flow rate and higher flow pressure on request
