Knick – 830 X Loop-Powered Process Indicator


Knick – 830 X Loop-Powered Process Indicator

The Model 830 X loop-powered digital indicators are universally applicable. The range (either 0 to 20 mA or 4 to 20 mA) is simply selected via terminals. Display starts working at an operating current of only 0.3 mA. The low voltage drop of 0.5 V allows application in current loops with low load voltage.


  • Digital indication without power supplies and supply leads
  • No signal interference due to power supply coupling
  • Power failure without effect on indication
  • No parasitic voltages
  • Unproblematic, extremely low-cost application in hazardous area
  • Universal range selection
  • Exchangeable unit symbols
