Multi-function measurement terminal

06 Jul 2016

With the new EL3751 EtherCAT Terminal, Beckhoff presents a new generation of I/Os for measurement applications. At 10,000 samples per second, a measurement accuracy of ±0.01 % and 24 bit resolution, the EL3751 with eXtreme Fast Control technology (XFC) provides measurement technology as part of the standard I/O system. Added to this is long-term stability, flexible filter configurations, and parameterization options for the analog input, which supports the measurement functions U, I, R, DMS (strain gauge) and RTD. Reliable and precision acquisition of measurement data offers potential to optimize machine efficiency and production quality. The EL3751 1-channel EtherCAT Terminal for analog measurement technology combines measurement accuracy: ±0.01 % of the full scale value for most interfaces, at 25°C (±5°C), with a sampling rate of up to 10,000 samples per second and 24 bit resolution (incl. sign). Other factors include long-term hardware stability through pre-aging, as well as configuration options for the nominal measuring range of the input channel. The integrated distributed clocks ensure synchronized sampling across the EtherCAT system. The "Extended Range" feature in the EL3751 enables effective measurement beyond the nominal measuring range, with possible extension up to 107%. To suppress aliasing effects, the input channel features two configurable numeric software filters up to 39th order FIR / 6th order IIR. The filters can be preselected or freely defined, so a band stop or a band pass can be implemented.
