The ELM314x economy line has been added to the EtherCAT measurement module family. This I/O system expansion simplifies the use of system-integrated precision measurement technology, which taps optimization and efficiency potentials both in production machines and for inline test benches. The modules are available in two, four, six and eight-channel versions. High-precision 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.
