Beckhoff recently extended the EtherCAT measurement modules by introducing ELM314x economy line that supplements the established ELM3x0x line with a lower cost 1 ksps class. This simplifies the use of the system-integrated precision measurement technology, which taps significant optimisation and efficiency potentials, both in production machines and inline test benches. The new ELM314x measurement modules are available in 2, 4, 6 and 8-channel versions. It is possible to have high-precision measurements with an accuracy of 100 ppm, in a wide temperature range from 10 to 40 °C at that. Each channel of the measurement modules can be set to current or voltage measurements, with a sampling rate of up to 1 ksps per channel. Also, it is possible to process the analogue signals in the ranges from ±1.25 to ±10 V, 0 to 10 V, ±20 mA or 0/4 to 20 mA. The economy line offers considerablyreduced channel costs but provides the same wide range of functions as the ELM3x0x line. These include freely adjustable two-stage filters, oversampling, distributed clocks, true RMS and scaler functions.
