ELM3502-0000 | 2-channel measuring bridge analysis, full/half/quarter bridge, 24 bit, 20 ksps

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.

There are variants with factory calibration certificate and a recalibration service for the ELM series in preparation.
