ModBUS Energy power meter with universal input and FTP, Post http, MQTT communication, UL listedR204 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. Some of its advanced features include: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 functionsDigital I/O Channels: Features 2 digital outputs and 2 independent inputs with 32-bit meters for active, reactive, and apparent energy metering.With our 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.
