The EL3356 EtherCAT Terminal is a 1-channel analog input module designed for measuring bridge applications. It facilitates direct connection of a resistor bridge or load cell using 4- or 6-wire connection technology. The terminal determines the ratio between the bridge voltage UD and the supply voltage UREF concurrently in the input circuit, calculating the final load value as a process value based on terminal settings.
Key features of the EL3356 include:
Support for automatic self-calibration, which can be deactivated as per requirements.
Integration of dynamic filters to ensure precise measurements, especially for slow weighings.
Measuring cycles of 10 ms, providing high precision in data acquisition.
