About Energy Monitoring

Comtac connects existing and additional meters to energy-monitoring systems through interfaces such as S0 and Modbus. Wireless, battery-powered devices can collect consumption readings without extensive signal cabling. For machine-level electricity measurements, current transformers and Rogowski coils can connect through Modbus or low-power networks such as LoRaWAN. The product range includes GRIDALYZER for low-voltage power monitoring, CLUEY MB for analog and digital field signals, and LPN Modbus Bridge devices for integrating Modbus equipment into LoRaWAN networks. These components support consumption monitoring across machines, production areas and buildings.

Questions and answers

Q: Must an existing meter be replaced?

A: Suitable meters can be connected through interfaces such as S0 or Modbus.

Q: Can machine consumption be measured separately?

A: The source describes current transformers and Rogowski coils for equipment-level measurement.

Q: Is a wired connection the only option?

A: No. The offering includes wireless collection and LoRaWAN integration options.
