TB20 Energy Meter
TB20 Energy Meter
Das Funktions-Modul Energy Meter nimmt alle wesentlichen Messwerte aus AC 230 V-Netzen bez?glich der Strom- und Spannungsmessung auf. Die Eingangsspannungen (3 Phasen + N) k?nnen direkt an das Modul angeschlossen werden.
Neben allgemeinen Statusinformationen k?nnen bis zu 7 Messwerte im Eingangsabbild durch die Parametrierung eingeblendet werden.
Der steuerbare Stromz?hler wird bei Ausfall des Systems nichtfl?chtig gespeichert.
Parameters for the module
- Overvoltage / undervoltage threshold
- Overcurrent threshold
