ELM3002-0235 | EtherCAT Terminal, 2-channel analog input, voltage, ±60 V…1200 V, 24 bit, 50 ksps, electrically isolated, 4 mm socket, externally calibratedNew

The ELM3002-0235 EtherCAT Terminal of the basic series is designed for high-voltage measurement on batteries and generators and supports the measuring ranges ±60/360/600 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 ELM3002-0235 with oversampling offers a maximum sampling rate of 50,000 samples per second. The terminal is equipped with 4 mm lab jacks.

The individual calibration certificate for each device, in accordance with ISO 17025 or DAkkS, depending on the device variant, can be downloaded here. These calibration certificates are issued for Beckhoff by an accredited service provider. Recalibration on request.

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.
