The ELM350x EtherCAT Terminals are designed for the evaluation of measuring bridges in full-bridge, half-bridge and quarter-bridge configuration. The terminals feature internally switchable supplementary resistors. The feed is integrated. Like all other parameters, the supply voltage is adjustable in the CoE. Irrespective of the signal configuration, all ELM modules have the same technological properties. The ELM350x modules for the evaluation of measuring bridges offer a maximum sampling rate of 10,000 or 20,000 samples per second. The 6-pin plug (push-in) can be removed for maintenance purposes without releasing the individual wires.

The individual calibration certificate for each device, in accordance with ISO 17025 or DAkkS, depending on the device variant, can be downloaded here. These calibration certificates are issued for Beckhoff by an accredited service provider. Recalibration on request.

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.
