Information About EL3356
The EL3356 is part of the Beckhoff EtherCAT I/O system and is engineered specifically for bridge-based sensing technologies, including strain gauges and load cells. It determines the ratio of bridge voltage (UD) to supply voltage (UREF) within the input circuit, generating precise digital load values based on module configuration. The terminal provides automatic self-calibration, optional deactivation, and multiple dynamic filter options to ensure accuracy even during slow or gradual weighing processes. Designed for industrial environments, the module integrates seamlessly via the EtherCAT E-bus, supports full-bridge measurement technology, and delivers stable, high-resolution data suitable for advanced automation tasks.
Key Features:
- Full-bridge measurement support: Direct connection for load cells and strain gauge bridges.
- 4-wire and 6-wire compatibility: Ensures accurate compensation and stable sensor readings.
- Simultaneous UD/UREF evaluation: Enables precise ratio-based load calculation.
- Self-calibration function: Maintains measurement accuracy; can be disabled if required.
- Dynamic filtering: Improves stability for slow or high-precision weighing operations.
- 10 ms measuring cycles: Provides fast response for real-time measurement tasks.
- 16-bit resolution with 32-bit output: Ensures high-fidelity digital representation of sensor signals.
- Wide measuring ranges: Supports ±27 mV bridge signals and ±13.8 V reference levels.
- High input impedance: >1 MΩ for UD and >200 kΩ for UREF for minimal sensor loading.
- Robust EMC and vibration resistance: Conforms to EN 61000-6-2/6-4 and EN 60068-2-6/27.
- E-bus powered: Simplifies system wiring within EtherCAT terminal arrays.
- ATEX and IECEx approved: Suitable for use in hazardous industrial environments.
The EL3356 delivers the reliability and precision required for high-accuracy weighing, force measurement, and bridge-sensor monitoring in EtherCAT automation systems.
