ELM3702-0000 | EtherCAT Terminal, 2-channel analog input, multi-function, 24 bit, 10 ksps

The EtherCAT Terminals from the ELM series were developed in order to enable the high-quality measurement of common electrical signals in the industrial environment. Flexibly usable measurement modules are especially useful in laboratory and testing technology environments. Therefore the ELM370x multi-function modules feature an input circuit that can be set to over 30 different types of electrical connection via EtherCAT: from voltages of ±60 V to ±20 mV, thus supporting thermocouples and IEPE, a current of ±20 mA, a resistance measurement of 5 kΩ and thus also temperature RTDs (Pt100, etc.), measuring bridges and potentiometers, and all of this with a 2- to 6-wire connection, depending on the type. Thus, most electrical measuring tasks can be solved with just a single module. There is a choice of different connection types: The ELM3704-0001 with its high-quality LEMO connectors is mainly designed for laboratory use, where sensor configurations are changed on a daily basis, but a stable and reliable plug connection is nevertheless required. The 6-pin version with push-in (ELM3704-0000/ELM3702-0000) on the other hand is ideal for industrial use where a plug is unplugged less frequently for maintenance purposes and fast wiring is much more important.

The other ELM3x0x modules are price-optimized versions of the ELM370x universal module and thus ideal for use in machines with planned and foreseeable usage scenarios in which the measurement method of an analog input channel does not need to be changed at runtime. In return, they may have advanced features, like the ELM360x modules (IEPE evaluation), which offer a switchable feed.

Available as ELM3702-0020 (or ELM3704-0020) variant with factory calibration certificate, with ISO 17025/DAkkS certificate on request. Support by Beckhoff recalibration service ZS9001 on request.
