ELM3002-0205 | EtherCAT Terminal, 2-channel analog input, voltage, ±60 V…±1200 V, 24 bit, 50 ksps, electrically isolated, 4 mm socket
ELM3002-0205 | EtherCAT Terminal, 2-channel analog input, voltage, ±60 V…±1200 V, 24 bit, 50 ksps, electrically isolated, 4 mm socket
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.
In preparation as variant with factory calibration certificate or ISO 17025-/DAkkS-compliant certificate including Beckhoff recalibration service.
Extensive documentation is available from Beckhoff sales, support or measurement@beckhoff.com.
