Functions and features

COMTRADE and PQDIF

  • Quick analysis due to a standardized file format
  • Data exchange directly from the device via SFTP and web server

Events and transients

  • Detect transients and events with real-time monitoring
  • Quick reaction times due to flexible settings for threshold values
  • 18 μs detection of transients

Power quality

  • Avoid downtime and interruptions whilst improving operating efficiency
  • Identify potential faults and protect systems from damage due to early detection of discrepancies in the measurement circuit
  • Record flickers and harmonics up to the 63rd harmonics current
  • Capture waveforms for root cause and event analysis

Comparator

  • 125 comparators in 32 comparison groups
  • Early warning if threshold values are exceeded and if discrepancies arise in consumption
  • Avoid expensive downtime via overcurrent alarms and collective fault signals
  • Reliable data transmission via OPC UA or modbus

Modbus Whitelisting

  • Improve operational safety via the modbus protocol with intelligent firewall
  • Secure data traffic and effectively isolate threats

Modbus

  • Gateway for seamless integration of other devices from downstream measurement levels
  • Extensive scope for communications with the combination of RS485 remote communication and high-speed Ethernet
  • Fast initial commissioning due to fixed patterns on Modbus address lists
  • Customized address lists Shift each value in accordance with specific requirements and create individual modbus addresses

Ethernet

  • Dual Ethernet with switched mode and daisy chain function
  • Maximize network capacity and safely connect other devices in series
  • Double the network security and flexibility: Integration into two networks for safe and efficient data management
  • Dedicated bandwidth for optimal power during critical processes

USB connection

  • Convenient and safe fault analysis directly on site via a connectable external display
  • Quick commissioning Quickly and easily upload device configurations and updates via USB

Measuring groups

  • With virtual meters - create and combine measured variables and measurement groups – totally without additional hardware
  • Use virtual parameters and reduce hardware costs considerably (savings of up to 25% per measurement channel)
  • Monitor and analyze energy consumption and power over several modules – even for 3- and 4-phase applications

Webserver

  • Integrated web server for ease of commissioning and configuration
  • Convenient, remote monitoring, diagnostics, and maintenance

Modularity

  • Expand with up to 13 modules
  • Up to 96 current measurement inputs
  • Up to 182 digital inputs
  • Up to 100 m bridging of measurement points via a connector module

Gridded averages

  • Saves critical 200 ms min/max values in order to recognize load peaks at an early stage and avoid costly downtime
  • Gridded or sliding average values: Recognize trends in good time and make decisions to ensure sustainable energy consumption

Communication

  • OPC UA
  • NTP
  • Modbus TCP/IP Gateway for up to 31 slaves

Peripherals
