Functionality: The EL3351 is a 1-channel analog input terminal designed for measuring bridge circuits (full bridge).
Measurement Capability: It directly connects to a resistor bridge, acquiring both bridge voltage (U_D) and supply voltage (U_REF) with 16-bit resolution.
Precision: The measurement is calculated using the formula U_D / U_REF, ensuring compensation for long-term and temperature drift.
Power Supply: Integrated 5V DC bridge supply, with an option for external power.
Filtering & Conversion: Features a configurable input filter (default 50 Hz) and a conversion time ranging from 2.5 ms to 800 ms.
Electrical Isolation: Provides 500V isolation between the E-bus and signal voltage.
Installation & Compatibility: Mounts on a 35mm DIN rail, supports TwinCAT System Manager for configuration.
Environmental Conditions: Operates within 0°C to 55°C, with 95% relative humidity (non-condensing).
Certifications: CE, CCC, UL, ATEX, IECEx approvals.
