Information About EL3702
The EL3702 is part of Beckhoff’s EL3xxx EtherCAT analog input terminal family, optimized for precision data acquisition and signal processing in automation systems. It features two differential voltage inputs capable of measuring ±10 V signals with 16-bit resolution, offering high accuracy and repeatability. The terminal’s oversampling technology allows multiple measurements per EtherCAT bus cycle, improving temporal resolution and enabling detailed signal analysis. Using distributed clocks, the EL3702 achieves sub-microsecond synchronization with other EtherCAT devices, making it suitable for applications requiring precise timing, such as motion control and vibration monitoring. The module’s high sampling rate, wide bandwidth, and robust electrical isolation ensure reliable performance in industrial measurement environments.
Key Features:
- Dual Differential Inputs: Provides two independent ±10 V analog input channels with high accuracy and electrical isolation.
- High-Speed Sampling: Supports sampling rates up to 100 ksamples/s per channel for real-time signal analysis.
- 16-Bit Resolution: Ensures fine measurement granularity across the full input range for precise voltage acquisition.
- Advanced Oversampling: Selectable oversampling factors (n = 1…100) enhance signal fidelity and timing resolution.
- Distributed Clock Synchronization: Enables sub-microsecond synchronization with other EtherCAT devices for coordinated system performance.
- Wide Bandwidth: Recommended input bandwidth of up to 30 kHz for dynamic signal capture.
- Low Measurement Error: Achieves < ±0.3% error up to 10 Hz, ensuring consistent accuracy across measurement ranges.
- Robust Industrial Design: Provides 500 V electrical isolation and operates from -25°C to +60°C for reliable use in harsh environments.
The EL3702 delivers the reliability and precision required for high-speed analog data acquisition, motion control, and signal monitoring in EtherCAT-based automation systems.
