Functions and features

Power quality

  • Harmonics analysis up to 63rd harmonic
  • Acquisition of short-term interruptions
  • Acquisition of transients
  • Display of waveforms (current and voltage)
  • Unbalance
  • Vector diagram

RCM (Residual Current Monitoring)

  • Continuous monitoring of residual currents (Residual Current Monitor, RCM)
  • Alarming in case a preset threshold fault current reached
  • Near-realtime reactions for triggering countermeasures
  • Permanent RCM measurement for systems in permanent operation without the opportunity to switch off
  • Ideal for the central earthing point in TN-S systems

Modern communications architecture via Ethernet

  • Ethernet interface and web server
  • Faster, better cost-optimised and more reliable communication system
  • High flexibility due to the use of open standards
  • Integration in PLC systems and BMS through additional interfaces
  • BACnet optionally available
  • Up to 4 ports simultaneous
  • Versatile IP protocols

Modbus Gateway function

  • Economical connection of devices without Ethernet interface
  • Integration of devices with Modbus-RTU interface possible
  • Data can be scaled and described
  • Minimised number of IP addresses required

Graphical programming

  • Comprehensive programming options (PLC functionality)
  • Jasic® source code programming
  • Sustainable functional expansions far beyond pure measurement
  • Complete APPs from the Janitza library

Powerful alarm management

  • Can be programmed via the graphic programming or Jasic ®source code
  • All measured values can be used
  • Can be arbitrarily, mathematically processed
  • Individual forwarding via email sending, switching of digital outputs, writing to Modbus addresses etc.
  • Watchdog APPs
  • Further alarm management functions via GridVis® -Service alarm management
