ELMx - Converters for infra communication with electricity meters

ELM – Converters for Electricity Meter Readings

The ELM converter is designed for remote reading of electricity consumption. It can be used with electricity meters commonly used by power distribution companies. Using the supplied cable, the converter connects to FIEDLER data loggers via an RS485 bus using the MODBUS RTU protocol.
The ELM converter enables infrared data communication with electricity meters in accordance with the ČSN EN 62056-21 standard in Protocol C mode, which defines bidirectional data exchange with switchable communication speeds.

  • Universal converter head compatible with the communication protocol of most commonly used electricity meters
  • Magnetic ring for quick installation of the converter head on the electricity meter
  • Reliable optical communication with the electricity meter
  • RS485 output signal using the standard MODBUS RTU protocol
  • Low current consumption and a wide supply voltage range from 5 to 28 V DC
  • Ability to connect multiple converters to a single data network and a single telemetry station
  • Compatible with the inputs of FIEDLER AMS data loggers and telemetry stations
  • Extensive support for data processing on the manufacturer’s server
  • Option to activate SMS alerts from a connected telemetry station when preset limit values are reached

Description

The small and simple H11 Smart Meters are designed for remote meter reading at a single consumption point. They can operate on a 2G or NB-IoT network.
To read up to several dozen electricity meters via a single RS485 data network, you can use a multi-channel telemetry station such as the H3, H7, or C8. The communication module in these units transmits the measured data to the server via an internal GSM/GPRS modem.
The server’s comprehensive software suite provides authorized users with graphical and tabular visualizations of measured data from individual consumption points, performs statistical calculations, and generates summary reports for further processing of the measured data.

Applications

  • Remote digital meter readings of electricity consumption in households, industrial facilities, or apartment buildings (the advantage of digital meter reading over conventional pulse counting is that it provides the absolute consumption value)
