ELM3102-0120 | EtherCAT Terminal, 2-channel analog input, multi-function, ±60 V, ±20 mA, 24 bit, 20 ksps, electrically isolated, factory calibrated
ELM3102-0120 | EtherCAT Terminal, 2-channel analog input, multi-function, ±60 V, ±20 mA, 24 bit, 20 ksps, electrically isolated, factory calibrated
The ELM3102-0120 EtherCAT Terminal in the basic series is a reduced version of the ELM3702-0101 intended for voltage and current measurement. It offers measuring ranges from +60 V to -20 mV and ±20 mA at a rapid sampling rate of 20 kSps per channel. The electrical isolation between channels allows it to detect signals that are at different or fluctuating potentials with high accuracy in complex environments.
The individual Beckhoff factory calibration certificate can be downloaded here for each device. Recalibration (ZS9001) is possible via Beckhoff Service.
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.
