Beckhoff latest EL3783 power monitoring oversampling terminal module for high-precision diagnosis of AC voltage, up to 690VAC monitoring.
Traditional automation and power measurement technologies are increasingly integrated, and Beckhoff will integrate the latest EL3783 power monitoring oversampling terminal module into a standard control system, making high-precision power grid analysis now also available for power generation systems and, most importantly, for voltages of 690V Within the three-phase AC system, you can directly in the PLC to achieve three-phase voltage and three-phase current synchronization analysis, analysis of data sampling frequency of up to 20k per second.
Beckhoff's EtherCAT Terminals The EL3783 measures the instantaneous value of each of three phases, measuring voltages up to 400/690 Vrms, measuring currents of 1 or 5 Arms and resolution of 16. This module measures six simultaneous measurements based on the principle of EtherCAT oversampling Channel, with a time resolution of up to 50 μs, significantly faster than the controller's mission cycle.The EtherCAT Distributed Clock feature allows simultaneous measurements with other EtherCAT devices in the system as well as accurate detection of grid linkage failures, regardless of system size How big
The control system can also provide exhaustive data with relevant details, for example, detailed calculations of the true RMS value for the analysis of the power and current curves, or for specific algorithms used by the user. In addition, EtherCAT Terminal module EL3783 with automatic current range switching function, the rated current of 1A signal can achieve 650% of the range and high accuracy, the maximum error of only 0.2% (full scale value).
The EL3783 terminal module can be used in conjunction with the TwinCAT 3 Power Monitoring Software Library TF3650 to provide a highly dynamic measurement system integrated into a standard PC control system for detailed power grid analysis. This ensures that voltage sags (low voltage ride throughs) should be taken For example, harmonic analysis can be used to enable condition monitoring without the additional cost of accelerating the sensor.
