Descripción
The analog EL3356 input terminal enables direct connection of a resistor bridge or load cell in a 4- or 6-wire connection technology. The ratio between the bridge voltage U. D, and the supply voltage U. REF, is determined simultaneously in the input circuit and the final load value is calculated as a process value on the basis of the settings in the terminal. With automatic self-calibration (can be deactivated) and dynamic filters the terminal with measuring cycles of 10 ms can be used for slow weighings with high precision.
