The Beckhoff EL3443 EtherCAT Terminal Analog Input features 3 current and 3 voltage inputs, enabling high-precision monitoring of electrical signals. With a maximum measuring voltage of 480 V AC and measuring current up to 1 A (via transformers), it supports both AC and DC measurement. Accuracy is maintained with an error margin of just 0.3% for voltage and current and 0.6% for calculated values, ensuring reliable results in industrial environments. The terminal supports net-synchronous updates with an update interval of one mains period (20 ms at 50 Hz), allowing precise mains monitoring and zero-crossing detection. Built with 2500 V electrical isolation, the EL3443 provides robust safety between signals and the E-bus. Its lightweight polycarbonate housing (12 × 100 × 68 mm, approx. 75 g) with LED indicators simplifies diagnostics and DIN rail mounting.
This EtherCAT Terminal Analog Input is engineered for harsh conditions, with an operating range of -25°C to +60°C, storage down to -40°C, and humidity tolerance up to 95%. It meets EMC immunity standards EN 61000-6-2/6-4 and conforms to vibration and shock resistance per EN 60068, ensuring durability in demanding environments. IP20 protection, CE and UL certifications, and optional distributed clocks further strengthen its suitability for industrial projects. Its efficient current consumption (120 mA on the E-bus) makes it a practical solution for high-density systems.
Applications of the EL3443 EtherCAT Terminal Analog Input include three-phase mains monitoring, energy measurement in process automation, and voltage/current analysis in building systems. Engineers use it for real-time power monitoring, while maintenance teams value its LED indicators and simple wiring for reduced downtime. For OEMs, it offers scalability within Beckhoff’s EtherCAT ecosystem, supporting integration into energy-efficient control architectures. Students and junior engineers also benefit from hands-on training with this module, gaining insights into industrial power measurement. With proven Beckhoff engineering, the EL3443 delivers long-term accuracy, reliability, and trust in advanced automation projects.
