Functions and features

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

High quality measurement

  • Constant true RMS measurement
  • Measurement process in accordance with IEC 61000-4-30
  • Certified accuracy of measurement according to class A
  • Continuous sampling of the voltage and current measurement inputs at 25,6 kHz
  • 512 measurement points per period
  • Recording of over 2,000 measured values per measurement cycle
  • Accuracy of active energy measurement: Class 0.2S
  • Fast measurement even enables the logging of rapid transients from 39 µs
  • Logging of currents and voltages (15 – 440 Hz)

User-friendly, colour graphical display with intuitive user guidance

  • High resolution colour graphical display 320 x 240, 256 colours, 6 buttons

  • Free name assignment for the digital IOs, e.g. if used as data logger
  • Modbus
  • Profibus
  • Ethernet (TCP/IP)
  • Digital IOs
  • BACnet (optional)
  • Configurable Firewall

Modern communications architecture via Ethernet

  • Simple integration in an Ethernet network
  • Reliable and cost-optimised establishment of communication
  • Ideal for Master-Slave structures
  • High flexibility due to the use of open standards
  • Integration in PLC systems and BMS through additional interfaces
  • Various IP protocols: SNMP, ICMP (Ping), NTP, FTP …
  • Up to 4 ports simultaneous

Programming / PLC functionality

  • Further processing of the measurement data in the measuring device (local intelligence)
  • Monitoring and alarm functions simple to program
  • Sustainable functional expansions far beyond pure measurement
