G4SR480V5A02CAA 1- or 3-phase voltage-, current-, power- and energy meter with Modbus RTU interface

  • Precise and fast universal energy meter for applications with high accuracy
  • The eCap measures voltages, currents, power, energy, and frequency along with the power factor and allows fully galvanically isolated transmission via the integrated Modbus RTU / RS485 interface
  • The required Modbus addresses for the measured values are listed in a separate Modbus register address document available on the website along with the eCap product
  • A single digital input and two digital outputs can be read and both outputs can be separately written via the Modbus RTU interface
  • All communication parameters may be set on the front of the device without any additional software
  • The status LEDs on the front of the eCap give a convenient indication about the device and communication condition
  • Indirect measurement via external current transformers. Nominal CT output current: 5 A

eCap – Performance sensor helps to save energy

  • The eCap from TELE Haase is a communication-enabled performance sensor for the accurate measurement of analog values for digital data processing
  • It transmits the measured data via Modbus to a PLC or via IoT module to the cloud and can be used universally with its flexible functionality
  • Retrofitted without great effort, the performance sensor collects all relevant digital data for the optimization of machines and systems, and helps customers save energy – which is easy on both the machines and the budget

Measuring and optimizing energy consumption

  • The TELE eCap helps customers use energy wisely and reduce operational expenses
  • The precise measurement of analog electrical values, which are read out from the machine by means of eCap, provides the user with a reliable database that can be digitally processed, prepared for analysis and visualized
  • Universally applicable, the eCap provides the right information for many different areas of application
  • Due to its fast data transfer, the eCap enables an immediate reaction to changing circumstances
  • In this way, the digital data obtained not only protects the equipment from damage or failure, but also helps to optimize efficiency and performance.

Data as a decisive factor

  • The eCap measures voltage and current with very high resolution and calculates many other values, such as power, power factor, energy or frequency
  • Communication takes place via Modbus RTU
  • Once measurement data from machines and plants are digitized, threshold values and functions of the plant can be set via the cloud or a PLC via software
  • In addition, the data can be recorded and used for data mining
  • This gives the user the ability to perform analysis, make forward-looking decisions to optimize the performance of their application
  • The eCap can be combined with PLCs, IoT gateways or similar systems, depending on the application
