Product Description:
The Beckhoff EL3443 is an EtherCAT terminal developed for accurate voltage and current measurement in three-phase industrial systems. This terminal is a variant of the EL EtherCAT Terminals series and can measure AC voltage of up to 690 V and alternating current within a range of 1 A to 5 A. Due to its ability to measure electrical parameters like voltage, current, power, energy, and power factor, it can be used for measuring and controlling power systems. It works with the frequency band of 45 Hz to 65 Hz and offers 16 bits of resolution for precise data acquisition. It measures only 15 mm in width; therefore, it can effectively optimize the spaces within control panels. It communicates using EtherCAT interface to ensure flexibility and high speed, and it is designed to be rail-mounted.
The EL3443 terminal has a protection class of IP20 to protect it against solid objects greater than 12mm in size in the form of fingers or any tools, but it does not offer water protection. This makes the terminal suitable for use in control cabinets or enclosures, so that it is not exposed to dust or moisture. This is important to provide proper protection so that the components are safe to use and last for relatively long periods.
The terminal uses a 24 V DC voltage source with an allowed fluctuation of -15 % to +20 % of the nominal value, which allows the input voltage to vary from 20.4 V to 28.8 V. It offers high flexibility in input power, making it suitable for industrial applications where the voltage may vary slightly from standard levels. A constant supply voltage of 24 VDC is required to power the terminal to provide reliable measurement and consistent power.
