ELM3002-0000 | 2-channel analog input terminal ±30 V…±20 mV, 24 bit, 20 ksps

The ELM300x EtherCAT Terminals are designed for flexible voltage measurement from 20 mV to 30 V in eleven measuring ranges. 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 ELM300x modules for voltage measurement offer a maximum sampling rate of 10,000 or 20,000 samples per second. The 2-pin plug (push-in) can be removed for maintenance purposes without releasing the individual wires.

There are variants with factory calibration certificate and a recalibration service for the ELM series in preparation.
