| About product | The EL3483 EtherCAT Terminal enables the monitoring of relevant electrical data of the supply network. The voltage is measured internally via direct connection of L1, L2, L3 and N. The internal measured values are compared with threshold values preset by the user. The result is available as digital information in the process image. The EL3483 checks for the correct phase order L1, L2, L3, phase failure, undervoltage and overvoltage, and possible phase asymmetry. An error bit is set in the case of an incorrect phase order or the failure of a phase. Should, for example, an asymmetry or voltage error occur, only a warning bit is set initially. In addition, an internally calculated mains quality factor provides information about the quality of the monitored voltage supply. The EL3483 offers basic functionality for mains monitoring and analysis. |
