digitalDIN railsingle-phase

Product Overview:R204 is an extremely versatile Universal Input Energy power meter with UL certification and a wide range of current measurement inputs. It can handle voltage-transduced currents, direct voltages, and Rogowski sensors with voltage output up to 333 mV. This instrument offers multiple insertion modes, including single-phase and three-phase 3/4-wire types. It is fully compatible with a range of communication protocols, including ModBUS RTU, ModBUS TCP-IP, and Peer-To-Peer.The module features a compact design with a depth of only 32 mm, enabling daisy-chain connection with automatic fault-bypass protection. The power meter provides voltage (0-10Vdc) and current (0-4-20mA) output signals. In addition, it offers advanced capabilities for measuring and recording harmonics up to the 55th order, with THD (total harmonic distortion) calculation, enabling a complete understanding of power quality.This device also performs the function of a Web Server and datalogger, allowing users to easily access key parameters and access data efficiently. The user also has the option of transferring data via FTP.Universal Input: Each device can be configured to accept single-phase, three-phase, TA, and TA with mV or Rogowski sensor inputs as required.MQTT and HTTP POST Supported: Integrating advanced protocols, it offers instant access to real-time energy data wherever you are.8MB Data Memory: Equipped with enhanced memory for data/event storage, harmonics up to 55°A and THD, ideal for system analysis and optimization.Maximum Flexibility: Also in the choice of power supply and Ethernet ports through which R204 offers ModBUS TCP-IP / ModBUS RTU gateway functions.Digital I/O Channels: Features 2 digital outputs and 2 independent inputs with 32-bit meters for active, reactive, and apparent energy metering.With the R204 power meter, you get a reliable and versatile tool for monitoring and managing your power grid.Technical Specifications:Power Supply: 10..30 VdcMax Power Consumption: 2.8 WIsolation: 3,500 Vac (to/from power circuits); 1,500 Vac (other circuits)Status Indicators: Power supply, digital channels, RS485 communication, data logger status, wiring error, Ethernet ports activityInstallation category: 600 V CAT IIIProgramming: via Web Server.
