ELM3102-0100 | EtherCAT Terminal, 2-channel analog input, multi-function, ±60 V, ±20 mA, 24 bit, 20 ksps, electrically isolated
ELM3102-0100 | EtherCAT Terminal, 2-channel analog input, multi-function, ±60 V, ±20 mA, 24 bit, 20 ksps, electrically isolated
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.
Available on request 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.
