5.10 CHARACTERISTIC VALUES

5.10.1 MEASURING RANGES

5.10.2 INPUTS, OUTPUTS AND INTERFACES

The energy meters are equipped with two pulse outputs or one bus output depending on model and variant.

5.10.3 TARIFF INPUTS

All instruments are equipped with 4 hardware-controlled tariff inputs. The tariffs are controlled via these tariff inputs by ap-

plying a certain voltage level:

 Level 0 = < 12 V

 Level 1 = 45 … 265 V

Depending on the combination of levels 0 and 1, the values measured at the instrument are recorded in the corresponding

tariff. Recording is thus possible in a daytime and a nighttime tariff, for example.

Instruments with bus (features W1, W2, W4, W7) have 4 additional software-controlled tariffs (not included in the scope of

MID approval). Further information can be found in the respective interface description. See chapter "Bus Connections (fea-

tures W1 / W2 / W4 / W7 / W8)" 52.

The active tariff appears at the display 33.

5.10.4 PULSE OUTPUTS

Pulses are transmitted via the pulse outputs (pulses per kWh). One of 4 pulse sources can be selected for each output: active

energy import, active energy export, reactive energy import or reactive energy export. Pulse frequency and duration can also

be adjusted on some models and variants.

Direct connection: Pulse frequency is proportional to measured energy.

Transformer connection: The permitted energy values are transmitted. In the case of feature Q0 and Q1, these are the sec-

ondary energy values. However, in the case of feature Q9, the primary energy values in consideration of the CT and VT value

are transmitted.

The pulse outputs are electrically isolated from the measuring circuit by means of an optocoupler.
