Beckhoff ELM314x Economy Line

January 15, 2019 | By MRO Magazine

Beckhoff Automation added ELM314x economy line to the EtherCAT measurement module family. This I/O system expansion simplifies the use of system-integrated precision measurement technology.

ELM314x measurement 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 of 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. Including 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.
