The EtherCAT terminal module el5072 of Beifu can directly connect up to two inductive displacement sensors, including LVDT and half bridge sensor or rvdt angular displacement sensor. Therefore, it can achieve accurate position and distance measurement in a compact, accurately scalable and cost-effective way (for example, in process control or controlled bonding process application scenarios). El5072 is only 12mm wide and can be installed in a standard EtherCAT I / O system to save space.
The excitation source integrated in el5072 can provide various parameterizable excitation frequency and voltage ranges. Its features include the ability to adaptively measure the signal range and switch the input impedance according to different probe types, And each channel has a digital input for setting and storing location values (including time stamp). This terminal module uses a 24 bit analog-to-digital converter to obtain high-precision measured values and directly output them as 32-bit position values that can be easily integrated into the control program. In addition, the terminal module also has the function of short circuit and overload diagnosis of excitation source, as well as the amplitude error of measured signals of each channel.
