EL3356-0020 | EtherCAT Terminal, 1-channel analog input, measuring bridge, full bridge, 24 bit, high-precision, factory calibrated
Distributed Clocks: the integrated time management system in EtherCAT
For demanding applications: calibrated analog inputs
Measurement technology easily configured: Analog EtherCAT input terminals.
Measurement technology simply integrated: With the analog EtherCAT Terminals.
The analog EL3356-0020 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), dynamic filters and distributed clock support, the terminal with measuring cycles of 100 µs can be used for fast and precise monitoring of torque or vibration sensors.
The individual Beckhoff factory calibration certificate can be downloaded here for each device. Recalibration (ZS9001) is possible via Beckhoff Service.
