The ELM3102-0100 EtherCAT Terminal of the basic series is a version of the ELM3702-0101 that is reduced to voltage and current measurement. It offers the measuring ranges +60 V…-20 mV and ±20 mA at a fast sampling rate of 20 ksps per channel. Due to the galvanic isolation between the channels, it can detect signals that are at different or fluctuating potentials with high accuracy in complex environments.

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.
