Beckhoff EL5072 EtherCAT terminal

Displacement measurement is one of the most important metrological tasks, both in the industrial production environment and in infrastructure monitoring. Examples include the measurement and inspection of workpiece geometry, the monitoring of press-fit and joining processes, inline quality assurance and building monitoring. The Beckhoff EL5072 EtherCAT terminal is designed to allow all commercially available inductive measuring probes to be integrated into the standard control platform and evaluated without great effort.

The integrated excitation source of the terminal provides a wide range of parameterisable excitation frequencies and voltages. Further features include an automatically adapted measuring signal range, switchable input impedances for different probe types, and one digital input per channel for setting and storing the position value (including time stamp). The measured value is determined with high precision by a 24-bit A/D conversion and output directly as a 32-bit position value that can be integrated into the control program. In addition, the terminal features diagnostics for short circuit and overload of the excitation source as well as amplitude errors of the measuring signal per channel.
