BECKHOFF EL3356 1CHANNEL ANALOG INPUT PRECISE LOAD CELL ANALYSIS
Quick Overview
Manufactured By: BECKHOFF
Manufacturer Part Number: EL3356
IMS Product Code: 1786708
Packaging: Sold Individually
Description:
Beckhoff EL3356 EtherCAT Terminal, 1-channel analog input, measuring bridge, full bridge, 16 bit
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 UD and the supply voltage UREF 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.
