ELM3504-0030 | 4-channel measuring bridge analysis, full/half/quarter bridge, 24 bit, 10 ksps, with external calibration certificate

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.

For the ELM350x-0030, an individual calibration certificate is available, currently as a choice of DAkkS or IS0 17025-compliant certificate. The certificate is issued by an accredited service provider in collaboration with Beckhoff. The desired calibration certificate can be downloaded from www.beckhoff.com/certificates using the respective serial number.
