EL3413 | Beckhoff EtherCAT Terminal

The EL3413 EtherCAT power measurement terminal is a further development of the EL3403. With up to 690 V AC the voltage inputs are optimized for direct monitoring of high-performance generators, as used in the wind power industry, for example. No upstream voltage transformer is required. The current inputs are galvanically isolated so that the terminal can be used in all common grounded current transformer configurations such as 2- or 3-transformer configurations with star or delta connection. The EL3413 can deal with simple network analysis up to the 21st harmonic analysis. Like all measured terminal data, the harmonic content can be read via the process data.The EL3413, EL3413-0001 and EL3413-0120 power measurement terminals have neutral conductor current measurement as standard since the 3rd quarter of 2015. At no additional cost to the end user, the terminals feature a shunt between pin 4 and pin 8, in order to enable direct neutral conductor analysis.
