The ELM370x multifunction terminals have a flexible input circuit that can be set to over 30 different electrical connection types via EtherCAT: from voltage ±60 V to ±20 mV and thus also thermocouple and IEPE, current ±20 mA, resistance measurement 5 kΩ and thus also temperature RTD (Pt100 etc.), measuring bridges and potentiometers, and all of these in turn in 2- to 6-wire connection depending on the type. Thus, most electrical measurement tasks can be solved with only one terminal.

The ELM3702-0101 adds helpful functions to this series: The two channels are not only independently adjustable as in all ELM3xxx terminals, but also galvanically isolated from each other and from the EtherCAT bus. Furthermore, it can also query TEDS data in the sensor, among other things, and supports 1000 Ω quarter bridges. With the LEMO plugs, the ELM3702-0101 is primarily designed for laboratory use, where sensor configurations are changed on a daily basis and a stable and reliable plug connection is still required.
