EtherCAT Terminals for mains monitoring, process control and power monitoring

Beckhoff’s four new EtherCAT I/O terminals cater to the demands of energy management in machine operation and in the energy industries.

 Together with the proven EL37x3 power monitoring oversampling terminals, Beckhoff’s four new EtherCAT Terminals provide a comprehensive product portfolio for a wide range of applications.

 

  • As the new standard power measurement terminal, the EL3443 3-phase EtherCAT Terminal is universally suitable for all process control tasks. It offers numerous new functions such as mains monitoring functionality, precise determination of zero voltage crossing and harmonics analysis. In addition, it is also suitable for DC systems.
  • The EL3453 3-phase EtherCAT Terminal for measuring voltages up to 690 V AC focuses on more demanding process control tasks. For this purpose, the terminal updates its process values with every half-wave, which corresponds to an interval of 10 min at 50 Hz. Four electrically isolated current measuring channels with freely adjustable measurement ranges for 100 mA, 1 A or 5 A, with a surge current capability of 60 A, are available.
  • As an economy version, the new EL3423 3-phase power measurement terminal is intended for cost-sensitive energy management solutions, especially in IoT applications. The parameters that can be measured are energy, power and a mains quality factor. These are recorded with an update interval that is adjustable from 10 sec to 1 hr. As a special feature, the measured parameters are available as average, minimum and maximum values.
  • The EL3483 3-phase mains monitoring terminal for voltage, frequency and phase enables optimum monitoring of the power supply to a machine, which is particularly advantageous for systems that are sensitive to voltage variations. The functions include threshold value monitoring of the internal measured values, and setting of warning and error bits in the process image.
