Information About EL3351
The EL3351 is part of Beckhoff’s EtherCAT I/O system and is designed to acquire measurement signals from resistor bridges in full bridge configuration. It integrates a 5 V DC bridge supply, eliminating the need for external excitation sources, and supports freely selectable nominal sensitivities calculated within the PLC. With a default input filter at 50 Hz and a configurable conversion time ranging from 2.5 to 800 ms, it ensures precise and adaptable measurement performance. The terminal consumes 170 mA from the E-bus, provides up to 400 samples per second, and is optimized for reliable signal acquisition under industrial conditions.
Key Features:
-
High-Resolution Measurement: 16-bit resolution with 32-bit presentation for detailed signal acquisition.
-
Full Bridge Support: Designed for connecting one resistor bridge in full bridge technology.
-
Configurable Measuring Range: ±20 mV input range and ±12 V reference range with high internal resistance.
-
Integrated Bridge Supply: Provides 5 V DC bridge excitation up to 20 mA without external hardware.
-
Flexible Conversion Time: Adjustable from 2.5 ms to 800 ms, allowing up to 400 samples per second.
-
Filter Options: Default 50 Hz input filter, fully parameterizable for application-specific needs.
-
Low Measurement Error: Accuracy within ±0.1% of full scale at 50 Hz filter.
-
Industrial Reliability: Conforms to EN standards for EMC, vibration, and shock resistance, with approvals including CE, UL, ATEX, CCC, and IECEx.
The EL3351 delivers the reliability and precision required for accurate strain gauge and sensor measurement in demanding industrial environments.
