Three phase electronical electric energy meter
EM Series Janitza Electronics

Electronic energy meters are mainly used for collecting data on effective and reactive consumption. Their standard area of application is in the field of energy management for cost centre analysis. There are various communication possibilities available in order to avoid time-consuming manual readings at site.

The effective pulses can be connected via two impulse outputs e.g. DDC, PLC, SCADA systems or the data logger ProData®. In the area of central building control systems the protocols M-Bus, EIB-KNX and Modbus RTU are available through additional communication modules which read the actual meters using an optical interface and which provide the respective value on the field bus through the interface.

The selection of additional values such as voltage, current, power, power factor and frequency together with effective and reactive energy are available on the bus cable through the communication modules. For consumption data collection, the EM meters can also be used as instruments for sub-metering for the UMG604 through Modbus RTU.
