This device also functions as a Web Server and datalogger, enabling users to access the main parameters easily and retrieve data efficiently. Users 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.
- 8MB data memory: Equipped with enhanced memory for storing data/events, harmonics up to the 55th order and THD, ideal for plant analysis and optimisation.
- Maximum Flexibility: including the choice of power supply and Ethernet ports through which R203 offers 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 R204 Power Analyser, you will have a reliable and versatile instrument for monitoring and managing your electrical network.
