Beckhoff EL5072 | EtherCAT Terminal, 2-channel displacement sensor interface, inductive

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.
