The 3-Phase Power Measurement Module (also called I/O Module) measures the<br />
electrical data in a 3-phase supply network.<br />
The 3 phase voltages are measured via connection to L1, L2, L3 and N. The<br />
currents are fed to I1+ and I1−, I2+ and I2−, I3+ and I3−, IN+ and IN− via current<br />
transformers resp. via ‘Rogowski’ coils to RC1+ and RC1−, RC2+ and RC2−,<br />
RC3+ and RC3−, RCN+ and RCN−. Based on these input signals the I/O module<br />
calculates numerous AC values like voltages, currents, powers (active, reactive<br />
and apparent), energies, power factors, phase shift angles and frequencies.<br />
Furthermore, an analysis of harmonic waves is carried out up to the 41 st harmonic.<br />
The measured values are available in the process image. Therefore, no high<br />
computing power is required from the higher-level controller.<br />
The calculated values indicate whether the load is inductive or capacitive and<br />
whether it consumes or generates energy. For this purpose a 4-quadrant display is<br />
incorporated in WAGO-I/O-CHECK.<br />
The I/O module provides a great number of measured values for a comprehensive<br />
supply network analysis via the fieldbus. By means of the measured values the<br />
operator can regulate the supply to a drive or machine in the best possible way<br />
and protect the installation from damage/failure.<br />
The I/O module 750-495 measures currents up to 1 A, 750-495/000-001 measures<br />
currents up to 5 A and 750-495/000-002 measures currents via ‘Rogowski’ coils<br />
RT500 up to 500 A or via RT2000 up to 2000 A.<br />
