TB20 Energy Meter

Das Funktions-Modul Energy Meter nimmt alle wesentlichen Messwerte aus AC 230 V-Netzen bezüglich der Strom- und Spannungsmessung auf. Die Eingangsspannungen (3 Phasen + N) können direkt an das Modul angeschlossen werden.
Neben allgemeinen Statusinformationen können bis zu 7 Messwerte im Eingangsabbild durch die Parametrierung eingeblendet werden.
Der steuerbare Stromzähler wird bei Ausfall des Systems nichtflüchtig gespeichert.

Parameters for the module
