This device also functions as a web server and data logger, allowing users to access the main parameters and data easily and efficiently. The user can also transfer data via FTP.
Some of its advanced features include:

  • Universal Input: Each device can be configured to accept single-phase, three-phase, CT, CT with mV or Rogowski sensor inputs according to requirements.
  • MQTT and HTTP POST support: By integrating advanced protocols, it provides immediate access to real-time energy data wherever you are.
  • 8 MB data memory: Equipped with enhanced memory for storing data/events, harmonics up to the 55th and THD, ideal for plant analysis and optimisation.
  • Maximum Flexibility: also in the choice of power supply and Ethernet ports through which R203 provides ModBUS TCP/IP / ModBUS RTU gateway functions
  • Digital I/O Channels: It features 2 digital outputs and 2 independent inputs with 32-bit counters for active, reactive and apparent energy metering.

With our R203-WF Network Analyser, you will have a reliable and versatile instrument for monitoring and managing your electrical network.
