The ELM3002-0205 EtherCAT Terminal of the basic series is designed for high-voltage measurement on batteries and generators and supports the measuring ranges 60/120/500 and 1200 V. The measuring range is selected in the CoE, as are the other setting options such as the filter parameters. Irrespective of the signal configuration, all ELM modules have the same technological properties. The ELM3002-0205 with oversampling offers a maximum sampling rate of 50,000 samples per second. The terminal is equipped with 4 mm lab jacks.

This terminal is also available as a variant with an individual calibration certificate. (See related products)

Extensive documentation is available from Beckhoff sales, support or measurement@beckhoff.com.

This ELM3xxx series measurement terminal enables efficient implementation of complex system-integrated data acquisition systems (DAQ) that place high demands on measurement accuracy and time synchronization.
