Beckhoff Automation el5072

The EL5072 EtherCAT Terminal is used for the direct connection of up to two inductive displacement sensors, which include measuring probes in LVDT and half bridge versions or inductive angle position sensors in RVDT version. The integrated excitation source provides a further area with various excitation frequencies and voltages. By internal switching and switchable input impedances, commercially available inductive sensors such as LVDT in 4-, 5-, 6-wire technology to half-bridge in 3- and 5-wire technology can be connected and evaluated.   Special features: evaluation of inductive measuring probes in LVDT, RVDT and half-bridge versions integrated excitation source with parameterizable frequencies and voltages switchable input impedances output of the measured value as a position value digital input for setting and saving the position value   All sensor parameters such as excitation frequency, excitation voltage, measuring range and sensitivity are set directly in the terminal. The measuring signal range is automatically adjusted; the measured value is directly output as a 32-bit position value. Inversion of the measuring signal and a reference position can be parameterized via the process data. Furthermore, short circuit and overload of the excitation source as well as amplitude errors of the measuring signal are diagnosed per channel and displayed by signal LEDs. One digital input is available per channel for setting and saving the current position value; a timestamp can be generated for the stored value. Precision measuring tasks in the area of position and distance measurement with inductive measuring probes can be successfully solved in this way with the EL5072.
