Beckhoff EL3483 EtherCAT Terminal

Description

The EL3483 is an EtherCAT terminal designed for monitoring the electrical parameters of a 3-phase supply network. It internally measures voltage by directly connecting to phases L1, L2, L3, and the neutral conductor. The terminal compares these values against user-defined thresholds and provides status information directly in the process image. It detects phase sequence, phase failure, undervoltage, overvoltage, and phase asymmetry, offering a comprehensive solution for grid analysis and mains monitoring.

Features

• Mains Monitoring: Real-time monitoring of voltage, frequency, and phase data.
• Diagnostics: Detects phase order, phase failure, asymmetry, and voltage thresholds (over/under).
• Process Data: Provides digital information in the process image; the EL3483-0060 variant additionally outputs current RMS voltage values.
• Mains Quality: Calculates a mains quality factor for power supply analysis.
• Flexibility: Supports optional single-phase operation.
• Compact Design: Slim 12 mm terminal housing with integrated status LEDs.

Installation Guidelines

• Mounting: Mount on a 35 mm DIN rail (EN 60715) using the locking mechanism. Side-by-side mounting is supported via double slot and key connections.
• Wiring: Use spring-actuated terminals for solid (0.08–2.5 mm²) or flexible (0.08–2.5 mm²) conductors. Strip wires to 8–9 mm.
• Safety: Ensure proper connection of L1, L2, L3, and N. Exercise caution during installation to avoid electric shock.
• Diagnostics: Monitor the front-panel LEDs. RUN indicates the EtherCAT state, System OK represents system health, and L1/L2/L3 LEDs indicate voltage status (green for normal, flashing for warning, off for prohibited range).
