THREE-PHASE ENERGY METERS APPLICATION
Energy meters have built-in optical (IR) communication port on the side.
It can be used for controlling Bistable switch – or in combination with SG smart gateway.
It can be used for direct communication with a PC to change settings of devices without any communication installed.
Optional the meter can be equipped with the following communications:
•
RS485
serial communication with the MODBUS protocol
•
M-BUS
serial communication
Communication modules enables data transmission and thus connection of the measuring places into the network for the
control and management with energy.
Besides of communication modules, there are also tariff input and built-in pulse output.
Tariff input provides measurement of two tariffs for selected energy registers.
Pulse output S01,2 is sending data to the devices for checking and monitoring consumed energy.
Energy meters are equipped with NFC communication for easy setting and downloading data via mobile app.
NFC communication is implemented for parametrization as well as for reading data (e.g. counters, measurements, etc.)
from the smart meter. Special application available from our internet site has to be used to perform such operations.
