Product Description:
The Beckhoff EL3403-0000 is an EtherCAT terminal designed for connecting a 3-phase current transformer. It provides accurate measurement of current in industrial applications, supporting a wide range of transformer inputs. This terminal is designed to support 3 inputs for current measurements and 3 inputs for voltage measurements. This allows for comprehensive monitoring of both current and voltage in a 3-phase system. The terminal can handle measuring voltages of up to 500 V AC for three-phase systems, with a maximum of 288 V AC for phase-to-neutral measurements (ULX-N). This makes it suitable for detailed monitoring and analysis of electrical systems.
The EL3403-0000 measures current with a maximum input of 1 A (AC) through the use of measuring transformers configured for x A/1 A. This setup allows for flexible integration with different current ranges. It offers high resolution, with measurement accuracy down to 1 µA for current, 0.1 mV for voltage, and 10 mW for power. The terminal is optimized for accuracy and comes with true RMS value calculation, which ensures accurate measurement of the effective value of AC currents. It also offers users flexibility in application with the option for single-phase operation, providing flexibility for applications that may not require three-phase monitoring.
This terminal has a current consumption of 120 mA from the E-bus, ensuring energy efficiency. It is designed to operate in temperatures ranging from -25°C to +60°C and can withstand relative humidity levels of up to 95% without condensation. This versatile terminal offers flexibility in installation accommodating both DIN rail mounting or side-by-side installation through a double slot and key connection. It comes with CE and UL approvals, indicating that it offers exceptional reliability in terms of performance and safety per industry standards.
