Description

To analyze three-phase AC power networks directly within the industrial fieldbus segment, the Beckhoff EL3403 provides precise, high-performance measurement values. This 3-channel analog input power measurement terminal is designed to calculate comprehensive electrical grid status parameters, including effective power, reactive power, apparent power, energy consumption, phase angle (cos phi), and frequency for each connected phase. Processing inputs up to 500 V AC directly, the module supports highly detailed diagnostics of energy distribution systems and industrial machinery. Non-intrusive current sensing up to 1 A (AC) is executed through external measuring transformers (such as x A/1 A), enabling flexible integration into existing power distribution frameworks.

Features

Mains-synchronous conversion with 16-bit resolution for premium signal acquisition.
Direct RMS value calculation for all applied voltage and current waveforms.
Comprehensive data calculation: delivers current, voltage, active/reactive/apparent power, energy, frequency, and phase angle values directly over the E-bus.
Optional single-phase operation mode for simplified monitoring on isolated lines.
Galvanic electrical isolation rating of 1500 V to isolate low-voltage logic from high-voltage measuring points.
Compact 12 mm design form factor optimizing space layout on industrial DIN rails.

Applications

Real-time energy management and sub-metering in industrial production facilities.
Dynamic load monitoring and diagnostic tracking on high-power three-phase AC motors.
Integration within power distribution plants and substation cabinets for utility tracking.
Predictive maintenance analytics based on power signature variations.
