December 12, 2018 – Beckhoff Automation has added the ELM314x economy line to the EtherCAT measurement module family, supplementing the ELM3x0x line with a lower cost 1 ksps class.
The ELM314x measurement modules are available in two, four, six and eight-channel versions. Measurements with an accuracy of 100 ppm are possible over a temperature range from 10 to 40 °C. Each channel in the measurement modules can be set to current or voltage measurements with a sampling rate of up to 1 ksps per channel. Analog signals in the ranges from ±1.25 to ±10 V, 0 to 10 V, ±20 mA or 0/4 to 20 mA can be processed.
The economy line provides the same range of functions as the ELM3x0x line. These include freely adjustable two-stage filters, oversampling, distributed clocks, true RMS and scaler functions. The diagnostic features for unattended, long-term use familiar from the ELM3x0x line are also implemented.
Sampling at 1 ksps per channel is suitable for a range of applications. In particular, the processes of moving machine components or the final inspection stage of inline test benches can be mapped with the economy line in order to control the processes. Typical examples include part geometry measurement on the fly, as well as weighing procedures, such as in bottling plants. In general, the ELM314x EtherCAT measurement modules are suitable for recording data from 10 V/20 mA sensors and for feeding real-time information directly back into the process.
