Thecurrents are fed to IL1, IL2, IL3 and IN via current transformers. Based on theseinput signals the I/O module calculates numerous values like voltages, currents,powers (active, reactive and apparent), energies, power factors, phase shift anglesand frequencies. Furthermore, an analysis of harmonic waves is carried out up tothe 41st harmonic. The measured values are available in the process image.Therefore, no high computing power is required from the higher-level controller.The calculated values indicate whether the load is inductive or capacitive andwhether it consumes or generates energy. For this purpose a 4-quadrant display isincorporated in WAGO-I/O-CHECK.The I/O module provides a great number of measured values for a comprehensivesupply network analysis via the fieldbus. By means of the measured values theoperator can regulate the supply to a drive or machine in the best possible wayand protect the installation from damage/failure.The I/O modules 750-494, 750-494/025-000 measure currents up to 1 A and 750-494/000-001, 750-494/025-001 measure currents up to 5 A.Pos : 24 /D okumentation allgemei n/Glieder ungs elemente/---Seitenwechs el--- @ 3\mod_1221108045078_0.doc x @ 21810 @ @ 1
